+
+<p>The <em>action bar</em> is arguably the most important structural element of an Android app. It's a
+dedicated piece of real estate at the top of each screen that is generally persistent throughout the
+app.</p>
+<p><strong>The main purpose of the action bar is to</strong>:</p>
+<ul>
+<li>Make important actions (such as <em>New</em> or <em>Search</em>, etc) prominent and accessible in a predictable
+ way.</li>
+<li>Support consistent navigation and view switching within apps.</li>
+<li>Reduce clutter by providing an action overflow for rarely used actions.</li>
+<li>Provide a dedicated space for giving your app an identity.</li>
+</ul>
+<p>If you're new to writing Android apps, note that the action bar is one of the most important design
+elements you can implement. Following the guidelines described here will go a long way toward making
+your app's interface consistent with the core Android apps.</p>
+<h2>General Organization</h2>
+<p>The action bar is split into four different functional areas that apply to most apps.</p>
+<img src="../static/content/action_bar_basics.png">
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-7 with-callouts">
+
+ <ol>
+ <li class="value-1"><h4>App icon</h4>
+ <p>
+
+The app icon establishes your app's identity. It can be replaced with a different logo or branding if
+you wish.
+Important: If the app is currently not displaying the top-level screen, be sure to display the Up
+caret to the left of the app icon, so the user can navigate up the hierarchy. For more discussion of
+Up navigation, see the "Navigation" pattern.
+
+<div class="figure">
+ <img src="../static/content/action_bar_pattern_up_app_icon.png">
+ <div class="figure-caption">
+ App icon with and without "up" affordance.
+ </div>
+</div>
+
+ </p>
+ </li>
+ </ol>
+
+ </div>
+ <div class="layout-content-col span-6 with-callouts">
+
+ <ol>
+ <li class="value-2"><h4>View control</h4>
+ <p>
+
+If your app displays data in different views, this segment of the action bar allows users to switch
+views. Examples of view-switching controls are drop-down menus or tab controls.
+
+ </p>
+ <p>
+
+If your app doesn't support different views, you can also use this space to display non-interactive
+content, such as an app title or longer branding information.
+
+ </p>
+ </li>
+ <li class="value-3"><h4>Action buttons</h4>
+ <p>
+
+Show the most important actions of your app in the actions section. Actions that don't fit in the
+action bar are moved automatically to the action overflow.
+
+ </p>
+ </li>
+ <li class="value-4"><h4>Action overflow</h4>
+ <p>
+
+Move less often used actions to the action overflow.
+
+ </p>
+ </li>
+ </ol>
+
+ </div>
+</div>
+
+
+<h2>Adapting to Rotation and Different Screen Sizes</h2>
+<p>One of the most important UI issues to consider when creating an app is how to adjust to screen
+rotation on different screen sizes.</p>
+<p>You can adapt to such changes by using <em>split action bars</em>, which allow you to distribute action bar
+content across multiple bars located below the main action bar or at the bottom of the screen.</p>
+
+<img src="../static/content/action_bar_pattern_rotation.png">
+<div class="figure-caption">
+ Split action bar showing action buttons at the bottom of the screen in vertical orientation.
+</div>
+
+<h2>Layout Considerations for Split Action Bars</h2>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-8 with-callouts">
+
+<p>When splitting up content across multiple action bars, you generally have three possible locations
+for action bar content:</p>
+<ol>
+<li><strong>Main action bar</strong></li>
+<li><strong>Top bar</strong></li>
+<li><strong>Bottom bar</strong></li>
+</ol>
+<p>If the user can navigate up the hierarchy from a given screen, the main action bar contains the up
+caret, at a minimum.</p>
+<p>To allow the user to quickly switch between the views your app provides, use tabs or a spinner in
+the top bar.</p>
+<p>To display actions and, if necessary, the action overflow, use the bottom bar.</p>
+
+ </div>
+ <div class="layout-content-col span-3">
+
+ <img src="../static/content/action_bar_pattern_considerations.png">
+
+ </div>
+</div>
+
+<h2>Contextual Action Bars</h2>
+<p>A <em>contextual action bar (CAB)</em> is a temporary action bar that overlays the app's action bar for the
+duration of a particular sub-task. CABs are most typically used for tasks that involve acting on
+selected data or text.</p>
+
+<img src="../static/content/action_bar_cab.png">
+<div class="figure-caption">
+ Contextual action bar shown in Browser and Gmail
+</div>
+
+<p>The selection CAB appears after a long press on a selectable data item triggers selection mode.</p>
+<p><strong>From here the user can</strong>:</p>
+<ul>
+<li>Select additional elements by touching them.</li>
+<li>Trigger an action from the CAB that applies to all selected data items. The CAB then
+ automatically dismisses itself.</li>
+<li>Dismiss the CAB via the navigation bar's Back button or the CAB's checkmark button. This removes
+ the CAB along with all selection highlights.</li>
+</ul>
+<p>Use CABs whenever you allow the user to select data via long press. You can control the action
+content of a CAB in order to insert the actions you would like the user to be able to perform.</p>
+<p>For more information, refer to the "Selection" pattern.</p>
+<h2>Action Bar Elements</h2>
+<h4>Tabs</h4>
+<p><em>Tabs</em> display app views concurrently and make it easy to explore and switch between them. Use tabs
+if you expect your users to switch views frequently.</p>
+
+<img src="../static/content/tabs_youtube.png">
+
+<p>There are two types of tabs: fixed and scrollable.</p>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-6">
+
+<h4>Scrollable tabs</h4>
+<p><em>Scrollable tabs</em> always take up the entire width of the bar, with the currently active view item in
+the center, and therefore need to live in a dedicated bar. Scrollable tabs can themselves be
+scrolled horizontally to bring more tabs into view.</p>
+<p>Use scrollable tabs if you have a large number of views or if you're unsure how many views will be
+displayed because your app inserts views dynamically (for example, open chats in a messaging app
+that the user can navigate between). Scrollable tabs should always allow the user to navigate
+between the views by swiping left or right on the content area as well as swiping the tabs
+themselves.</p>

+
+<div class="layout-content-row">
+ <div class="layout-content-col span-6">
+
+<h4>Fixed tabs</h4>
+<p><em>Fixed tabs</em> are always visible on the screen, and can't be moved out of the way like scrollable
+tabs. Fixed tabs in the main action bar can move to the top bar when the screen orientation changes.</p>
+
+ </div>
+ <div class="layout-content-col span-7">

+</div>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-6">
+
+<h4>Spinners</h4>
+<p>A <em>spinner</em> is a drop-down menu that allows users to switch between views of your app. </p>
+<p><strong>Use spinners rather than tabs in the main action bar if</strong>:</p>
+<ul>
+<li>You don't want to give up the vertical screen real estate for a dedicated tab bar.</li>
+<li>You expect your app's users to switch views infrequently.</li>
+</ul>

+ <div class="layout-content-col span-7">

+ <img src="../static/content/action_bar_pattern_spinner.png">
+ <div class="figure-caption">
+ Action bar spinner from Calendar application.
+ </div>
+
+ </div>
+</div>
+
+<h4>Action buttons</h4>
+<p><em>Action buttons</em> on the action bar surface your app's most important activities. Think about which
+buttons will get used most often, and order them accordingly. Depending on available screen real
+estate, the system shows your most important actions as action buttons and moves the rest to the
+action overflow.</p>
+
+<img src="../static/content/action_bar_pattern_action_icons.png">
+<div class="figure-caption">
+ A sampling of action buttons used throughout the Gmail application.

+<p>For guidance on prioritizing actions, use the FIT scheme.</p>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-4">
+
+<p><strong>F &mdash; Frequent</strong></p>
+<ul>
+<li>Will people use this action at least 7 out of 10 times they visit the screen?</li>
+<li>Will they typically use it several times in a row?</li>
+<li>Would taking an extra step every time truly be burdensome?</li>
+</ul>
+
+ </div>
+ <div class="layout-content-col span-4">
+
+<p><strong>I &mdash; Important</strong></p>
+<ul>
+<li>Do you want everyone to discover this action because it's especially cool or a selling point?</li>
+<li>Is it something that needs to be effortless in the rare cases it's needed?</li>
+</ul>
+
+ </div>
+ <div class="layout-content-col span-4">
+
+<p><strong>T &mdash; Typical</strong></p>
+<ul>
+<li>Is it typically presented as a first-class action in similar apps?</li>
+<li>Given the context, would people be surprised if it were buried in the action overflow?</li>
+</ul>
+
+ </div>
+</div>
+
+<p>If either F, I, or T apply, then it's appropriate for the action bar. Otherwise, it belongs in the
+action overflow.</p>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-6">
+
+<h4>Action overflow</h4>
+<p>The action overflow in the action bar provides access to your app's less frequently used actions.
+The overflow icon only appears on phones that have no menu hardware keys. Phones with menu keys
+display the action overflow when the user presses the key.</p>
+
+ </div>
+ <div class="layout-content-col span-7">
+
+ <img src="../static/content/action_bar_pattern_overflow.png">
+ <div class="figure-caption">
+ Action overflow is pinned to the right side.
+ </div>
+
+ </div>
+</div>
+
+<p>How many actions will fit in the main action bar? Action bar capacity is controlled by the following
+rules:</p>
+<ul>
+<li>Action buttons in the main action bar may not occupy more than 50% of the bar's width. Action
+ buttons on bottom action bars can use the entire width.</li>
+<li>The screen width in density-independent pixels
+ (<acronym title="Density-independent pixels. One dp is one pixel on a 160 dpi screen.">dp</acronym>)
+ determine the number of items that will fit in the main action bar:<ul>
+<li>smaller than 360 dp = 2 icons</li>
+<li>360-499 dp = 3 icons</li>
+<li>500-599 dp = 4 icons</li>
+<li>600 dp and larger = 5 icons</li>
+</ul>
+</li>
+</ul>
+
+<img src="../static/content/action_bar_pattern_table.png">
+<div class="figure-caption">
+ In the above table "o" denotes an action bar item and "=" an overflow icon.
+</div>
+
+<h4>Sharing data</h4>
+<p>Whenever your app permits sharing of data, such as images or movie clips, use a <em>share action
+provider</em> in your action bar. The share action provider is designed to speed up sharing by
+displaying the most recently used sharing service next to a spinner button that contains other
+sharing options.</p>
+
+<img src="../static/content/action_bar_pattern_share_pack.png">
+<div class="figure-caption">
+ The Gallery app's share action provider with extended spinner for additional sharing options.
+</div>
+
+<h2>Action Bar Checklist</h2>
+<p>When planning your split action bars, ask yourself questions like these:</p>
+<h4>How important is view navigation to the task?</h4>
+<p>If view navigation is very important to your app, use tabs (for fastest view-switching) or spinners.</p>
+<h4>Which of the app's actions need to be consistently available directly from the action bar, and which can be moved to the action overflow?</h4>
+<p>Use the <acronym title="Frequent, Important or Typical">FIT</acronym> scheme to decide if actions
+are displayed at the top-level or can be moved to the action overflow. If the number of top-level
+actions exceeds the capacity of the main action bar, display them separately in a bottom action bar.</p>
+<h4>What else is important enough to warrant continuous display?</h4>
+<p>Sometimes it is important to display contextual information for your app that's always visible.
+Examples are the number of unread messages in a messaging inbox view or the Now Playing information
+in a music player. Carefully plan which important information you would like to display and
+structure your action bars accordingly.</p>

+<p>Apps come in many varieties that address very different needs. For example:</p>
+<ul>
+<li>Apps such as Calculator or Camera that are built around a single focused activity handled from a
+ single screen</li>
+<li>Apps such as Phone whose main purpose is to switch between different activities without deeper
+ navigation</li>
+<li>Apps such as Gmail or Market that combine a broad set of data views with deep navigation</li>
+</ul>
+<p>Your app's structure depends largely on the content and tasks you want to surface for your users.</p>
+<h2>General Structure</h2>
+<p>A typical Android app consists of top level and detail/edit views. If the navigation hierarchy is
+deep and complex, category views connect top level and detail views.</p>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-9">
+
+ <img src="../static/content/app_structure_overview.png">
+
+ </div>
+ <div class="layout-content-col span-4">
+
+<h4>Top level views</h4>
+<p>The top level of the app typically consists of the different views that your app supports. The views
+either show different representations of the same data or expose an altogether different functional
+facet of your app.</p>
+<div class="vspace size-3">&nbsp;</div>
+
+<h4>Category views</h4>
+<p>Category views allow you to drill deeper into your data.</p>
+<div class="vspace size-11">&nbsp;</div>
+
+<h4>Detail/edit view</h4>
+<p>The detail/edit view is where you consume or create data.</p>
+
+ </div>
+</div>
+
+<h2>Top Level</h2>
+<p>The layout of your start screen requires special attention. This is the first screen people see
+after launching your app, so it should be an equally rewarding experience for new and frequent
+visitors alike.</p>
+<p>Ask yourself: "What are my typical users most likely going to want to do in my app?", and structure
+your start screen experience accordingly.</p>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-5">
+
+<h4>Put content forward</h4>
+<p>Many apps focus on the content display. Avoid navigation-only screens and instead let people get to
+the meat of your app right away by making content the centerpiece of your start screen. Choose
+layouts that are visually engaging and appropriate for the data type and screen size.</p>
+
+ </div>
+ <div class="layout-content-col span-8">
+
+ <img src="../static/content/app_structure_market.png">
+ <div class="figure-caption">
+ Market's start screen primarily allows navigation into the stores for Apps, Music, Books, and
+ Games. It is also enriched with tailored recommendations and promotions that surface content
+ of interest to the user. Search is readily available from the action bar.
+ </div>
+
+ </div>
+</div>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-5">
+
+<h4>Set up action bars for navigation and actions</h4>
+<p>All screens in your app should display action bars to provide consistent navigation and surface
+important actions.</p>
+<p>At the top level, special considerations apply to the action bar:</p>
+<ul>
+<li>Use the action bar to display your app's icon or title.</li>
+<li>If your top level consists of multiple views, or if switching between data from different user
+ accounts is a significant use case, make sure that it's easy for the user to navigate between them
+ by adding view controls to your action bar.</li>
+<li>If your app allows people to create content, consider making the content accessible right from the
+ top level.</li>
+<li>If your content is searchable, include the Search action in the action bar so people can cut
+ through the navigation hierarchy.</li>
+</ul>
+
+ </div>
+ <div class="layout-content-col span-8">
+
+ <img src="../static/content/app_structure_gmail.png">
+ <div class="figure-caption">
+ Email is about productivity, so an efficient, easy-to-skim list with higher data density works
+ well. Navigation supports switching between accounts and recent labels. Icons for creating a
+ new message or searching are prominent in the split action bar at the bottom.
+ </div>
+
+ </div>
+</div>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-5">
+
+<h4>Create an identity for your app</h4>
+<p>Creating an identity for your app goes beyond the action bar. Your app communicates its identity
+through its data, the way that data is arranged, and how people interact with it. Especially for
+media-rich applications, try to create unique layouts that showcase your data and go beyond the
+monotony of simple list views.</p>
+
+ </div>
+ <div class="layout-content-col span-8">
+
+ <img src="../static/content/app_structure_music_lndscp.png">
+ <div class="figure-caption">
+ The 3D carousel celebrates cover art and establishes a unique identity for the Music app.
+ Defaulting to the Recent view keeps the focus on music the user has been listening to lately.
+ </div>
+
+ </div>
+</div>
+
+<h2>Categories</h2>
+<p>Generally, the purpose of a deep, data-driven app is to navigate through organizational categories
+to the detail level, where data can be viewed and managed. Minimize perceived navigation effort by
+keeping your apps shallow.</p>
+<p>Even though the number of vertical navigation steps from the top level down to the detail views is
+typically dictated by the structure of your app's content, there are several ways you can cut down
+on the perception of onerous navigation.</p>
+<h4>Use tabs to combine category selection and data display</h4>
+<p>This can be successful if the categories are familiar or the number of categories is small. It has
+the advantage that a level of hierarchy is removed and data remains at the center of the user's
+attention. Navigating laterally between data-rich categories is more akin to a casual browsing
+experience than to an explicit navigation step.</p>
+
+<div class="vspace size-1">&nbsp;</div>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-8">
+
+<p>If the categories are familiar, predictable, or closely related, use scrolling tabs (where not all
+items are in view simultaneously). Keep the number of scrolling tabs at a manageable level to
+minimize navigational effort. Rule of thumb: no more than 5&ndash;7 tabs.</p>
+
+ <img src="../static/content/app_structure_scrolltabs.png">
+ <div class="figure-caption">
+ Market uses tabs to simultaneously show category choice and content. To navigate between
+ categories, users can swipe left/right on the content.
+ </div>
+
+ </div>
+ <div class="layout-content-col span-5">
+
+<p>If the categories in the tabs are not closely related, favor fixed tabs, so that all categories are
+in view at the same time.</p>
+
+ <img src="../static/content/app_structure_fixedtabs.png">
+ <div class="figure-caption">
+ YouTube uses fixed tabs to switch between different, relatively unrelated functional areas.
+ </div>
+
+
+ </div>
+</div>
+
+<h4>Allow cutting through hierarchies</h4>
+<p>Take advantage of shortcuts that allow people to reach their goals quicker. To allow top-level
+invocation of actions for a data item from within list or grid views, display prominent actions
+directly on list view items using drop-downs or split list items. This lets people invoke actions on
+data without having to navigate all the way down the hierarchy.</p>
+
+<img src="../static/content/app_structure_shortcut_on_item.png">
+<div class="figure-caption">
+ Music allows the user to act upon a data item (song) from within the category view (album),
+ thereby removing the need to navigate all the way down to the song's detail view.
+</div>
+
+<h4>Acting upon multiple data items</h4>
+<p>Even though category views mostly serve to guide people to content detail, keep in mind that there
+are often good reasons to act on collections of data as well.</p>
+<p>For example, if you allow people to delete an item in a detail view, you should also allow them to
+delete multiple items in the category view. Analyze which detail view actions are applicable to
+collections of items. Then use multi-select to allow application of those actions to multiple items
+in a category view.</p>
+<h2>Details</h2>
+<p>The detail view allows you to view and act on your data. The layout of the detail view depends on
+the data type being displayed, and therefore differs widely among apps.</p>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-4">
+
+<h4>Layout</h4>
+<p>Consider the activities people will perform in the detail view and arrange the layout accordingly.
+For immersive content, make use of the lights-out mode to allow for distraction-free viewing of
+full-screen content.</p>
+
+ <img src="../static/content/app_structure_people_detail.png">
+
+ </div>
+ <div class="layout-content-col span-9">
+
+ <img src="../static/content/app_structure_book_detail_page_flip.png">
+ <div class="figure-caption">
+ Google Books' detail view is all about replicating the experience of reading an actual book.
+ The page-flip animation reinforces that notion. To create an immersive experience the app
+ enters lights-out mode, which hides all system UI affordances.
+ </div>
+
+ <div class="figure-caption">
+ The purpose of the People app's detail view is to surface communication options. The list view
+ allows for efficient scanning and quick access of phone numbers, email addresses and other
+ information items. Split items are used to combine calling and messaging into one compact line
+ item.
+ </div>
+ </div>
+</div>
+
+<h4>Make navigation between detail views efficient</h4>
+<p>If your users are likely to want to look at multiple items in sequence, allow them to navigate
+between items from within the detail view. Use swipe views or other techniques, such as filmstrips,
+to achieve this.</p>
+
+<img src="../static/content/app_structure_gmail_swipe.png">
+<div class="figure-caption">
+ Gmail using swipe views to navigate from detail view to detail view.
+</div>
+
+<img src="../static/content/app_structure_gallery_filmstrip.png">
+<div class="figure-caption">
+ In addition to supporting swipe gestures to move left or right through images, Gallery provides a
+ filmstrip control that lets people quickly jump to specific images.
+</div>
+
+<h2>Checklist</h2>
+<ul>
+<li>
+<p>Find ways to display useful content on your start screen.</p>
+</li>
+<li>
+<p>Use action bars to provide consistent navigation.</p>
+</li>
+<li>
+<p>Keep your hierarchies shallow by using horizontal navigation and shortcuts.</p>
+</li>
+<li>
+<p>Use multi-select to allow the user to act on collections of data.</p>
+</li>
+<li>
+<p>Allow for quick navigation between detail items with swipe views.</p>

+
+
+<p>When writing an app for Android, keep in mind that Android devices come in many different screen
+sizes and types. Make sure that your app consistently provides a balanced and aesthetically pleasing
+layout by adjusting its content to varying screen sizes and orientations.</p>
+<p><em>Panels</em> are a great way for your app to achieve this. They allow you to combine multiple views into
+one compound view when a lot of horizontal screen real estate is available and by splitting them up
+when less space is available.</p>
+<h2>Combining Multiple Views Into One</h2>
+<p>On smaller devices your content is typically divided into a master grid or list view and a detail
+view. Touching an item in the master view opens a different screen showing that item's detail
+information.</p>
+
+<img src="../static/content/multipane_views.png">
+
+<p>Because tablets have more screen real estate than phones, you can use panels to combine the related
+list and detail views into a single compound view. This uses the additional space more efficiently
+and makes navigating the app easier. </p>
+
+<img src="../static/content/multipane_view_tablet.png">
+
+<p>In general, use the pane on the right to present more information about the item you selected in the
+left pane. Make sure to keep the item in the left pane selected in order to establish the
+relationship between the panels.</p>
+<h2>Compound Views and Orientation Changes</h2>
+<p>Screens should have the same functionality regardless of orientation. If you use a compound view in
+one orientation, don't split it up when the user rotates the screen. There are several techniques
+you can use to adjust the layout after orientation change while keeping functional parity intact.</p>
+
+<div class="layout-content-row">

+

+ <div class="layout-content-col span-5">
+
+<h4>Stretch/compress</h4>
+<p>Adjust the column width of your left pane to achieve a balanced layout in both orientations.</p>

+ <div class="layout-content-col span-5">
+
+<h4>Expand/collapse</h4>
+<p>When the device rotates, collapse the left pane view to only show the most important information.
+Provide an <em>expand</em> control that allows the user to bring the left pane content back to its original
+width and vice versa.</p>

+<h4>Show/hide</h4>
+<p>After rotating the device, show the right pane in fullscreen view. Use the Up icon in the action bar
+to show the left panel and allow navigation to a different email. Hide the left panel by touching
+the content in the detail panel.</p>
+
+ </div>
+</div>
+
+<h2>Checklist</h2>
+<ul>
+<li>
+<p>Plan in advance on how your app scales to different screen sizes and screen orientations.</p>
+</li>
+<li>
+<p>Identify the most appropriate method for the panels in your compound views to reorganize
+ themselves when screen orientation changes.</p>
+</li>
+<li>
+<p>Look for opportunities to consolidate your views into multi-panel compound views.</p>
+</li>
+<li>
+<p>Make sure that your screens provide functional parity after the screen orientation
+ changes.</p>

+
+<p>Consistent navigation is an essential component of the overall user experience. Few things frustrate
+users more than basic navigation that behaves in inconsistent and unexpected ways. Android 3.0
+introduced significant changes to the global navigation behavior. Thoughtfully following the
+guidelines for Back and Up will make your app's navigation predictable and reliable for your users.</p>
+<p>Android 2.3 and earlier relied upon the system <em>Back</em> button for supporting navigation within an
+app. With the introduction of action bars in Android 3.0, a second navigation mechanism appeared:
+the <em>Up</em> button, consisting of the app icon and a left-point caret.</p>
+
+<img src="../static/content/navigation_with_back_and_up.png">
+
+<h2>Up vs. Back</h2>
+<p>The Up button is used to navigate within an application based on the hierarchical relationships
+between screens. For instance, if screen A displays a list of items, and selecting an item leads to
+screen B (which presents that item in more detail), then screen B should offer an Up button that
+returns to screen A.</p>
+<p>If a screen is the topmost one in an app (i.e. the home of the app), it should not present an Up
+button.</p>
+<p>The system Back key is used to navigate based on the history of screens the user has recently seen,
+in reverse chronological order&mdash;in effect, the temporal relationships between screens.</p>
+<p>When the previously viewed screen is also the hierarchical parent of the current screen, pressing
+the Back key will have the same result as pressing an Up button -- this is a common occurrence.
+However, unlike the Up button, which ensures the user remains within your app, the Back key can
+return the user to the Home screen, or even to a different application.</p>
+
+<img src="../static/content/navigation_up_vs_back_gmail.png">
+
+<p>The Back key also supports a few behaviors not directly tied to screen-to-screen navigation:</p>
+<ul>
+<li>Back dismisses floating windows (dialogs, popups)</li>
+<li>Back dismisses contextual action bars, and remove highlight from selected items</li>
+<li>Back hides the onscreen keyboard (IME)</li>
+</ul>
+<h2>Navigation Within Your App</h2>
+<h4>Navigating to screens with multiple entry points</h4>
+<p>Sometimes a screen doesn't have a strict position within the app's hierarchy, and can be reached
+from multiple entry points&mdash;e.g., a settings screen which can be navigated to from any screen
+in your app. In this case, the Up button should choose to return to the referring screen, behaving
+identically to Back.</p>
+<h4>Changing view within a screen</h4>
+<p>Changing view options for a screen does not change the behavior of Up or Back: the screen is still
+in the same place within the app's hierarchy, and no new navigation history is created.</p>
+<p>Examples of such view changes are:</p>
+<ul>
+<li>Switching views using tabs and/or left-and-right swipes</li>
+<li>Switching views using a dropdown (aka collapsed tabs)</li>
+<li>Filtering a list</li>
+<li>Sorting a list</li>
+<li>Changing display characteristics (e.g. zooming)</li>
+</ul>
+<h4>Navigating between sibling screens</h4>
+<p>When your app supports navigation from a list of items to a detail view of one of those items, it's
+often desirable to support direction navigation from that item to another one which precedes or
+follows it in the list. For example, in Gmail, it's easy to swipe left or right from a conversation
+to view a newer or older one in the same Inbox. Just as when changing view within a screen, such
+navigation does not change the behavior of Up or Back.</p>
+
+<img src="../static/content/navigation_between_siblings_gmail.png">
+
+<p>However, a notable exception to this occurs when browsing between "related" detail views not tied
+together by the referring list&mdash;for example, when browsing in the Market between apps from
+the same developer, or albums by the same artist. In these cases, following each link does create
+history, causing the Back button to step through each screen of related content which has been
+viewed. Up should continue to bypass these related screens and navigate to the most recently viewed
+container screen.</p>
+
+<img src="../static/content/navigation_between_siblings_market1.png">
+
+<p>You have the ability to make the Up behavior even smarter based on your knowledge of detail
+view. If we extend our Market sample from above, imagine the user has navigated from the last Book
+viewed to the details for the Movie adaptation. In that case, Up can return to a container (Movies)
+which the user had not previously navigated through.</p>
+
+<img src="../static/content/navigation_between_siblings_market2.png">
+
+<h2>Navigation From Outside Your App</h2>
+<p>There are two categories of navigation from outside your app to screens deep within the app's
+hierarchy:</p>
+<ul>
+<li>App-to-app navigation, such as via intent completion.</li>
+<li>System-to-app navigation, such as via notifications and home screen widgets.</li>
+</ul>
+<p>Gmail provides examples of each of these. For app-to-app navigation, a "Share" intent goes directly
+to the compose screen. For system-to-app navigation, both a new message notification and a home
+screen widget can bypass the Inbox screen, taking the user directly to a conversation view.</p>
+<h4>App-to-app navigation</h4>
+<p>When navigating deep into your app's hierarchy directly from another app via an intent, Back will
+return to the referring app.</p>
+<p>The Up button is handled is follows:
+- If the destination screen is typically reached from one particular screen within your app, Up
+ should navigate to that screen.
+- Otherwise, Up should navigate to the topmost ("Home") screen of your app.</p>
+<p>For example, after choosing to share a book being view in Market, the user navigates directly to the
+Gmail's compose screen. From there, Up returns to the Inbox (which happens to be both the typical
+referrer to compose, as well as the topmost screen of the app), while Back returns to Market.</p>
+
+<img src="../static/content/navigation_from_outside_up.png">
+
+<h4>System-to-app navigation</h4>
+<p>If the your app was reached via the system mechanisms of notifications or home screen widgets, Up
+behaves as described for app-to-app navigation, above.</p>
+<p>For the Back key, you should make navigation more predictably by inserting into the task's back
+stack the complete upward navigation path to the app's topmost screen. This way, a user who has
+forgotten how they entered your app can safely navigate to the app's topmost screen before exiting
+it.</p>
+<p>For example, Gmail's Home screen widget has a button for diving directly to its compose screen.
+After following that path, the Back key first returns to the Inbox, and from there continues to
+Home.</p>

+<p>The notification system allows your app to keep the user informed about important events, such as
+new messages in a chat app or a calendar event.</p>
+<p>To create an app that feels streamlined, pleasant, and respectful, it is important to design your
+notifications carefully. Notifications embody your app's voice, and contribute to your app's
+personality. Unwanted or unimportant notifications can annoy the user, so use them judiciously.</p>
+<h4>When to display a notification</h4>
+<p>To create an application that people love, it's important to recognize that the user's attention and
+focus is a resource that must be protected. To use an analogy that might resonate with software
+developers, the user is not a method that can be invoked to return a value. The user's focus is a
+resource more akin to a thread, and creating a notification momentarily blocks the user thread as
+they process and then dismiss the interruptive notification.</p>
+<p>Android's notification system has been designed to quickly inform users of events while they focus
+on a task, but it is nonetheless still important to be conscientious when deciding to create a
+notification.</p>
+<p>While well behaved apps generally only speak when spoken to, there are some limited cases where an
+app actually should interrupt the user with an unprompted notification.</p>
+<p>Notifications should be used primarily for <strong>time sensitive events</strong>, and especially if these
+synchronous events <strong>involve other people</strong>. For instance, an incoming chat is a real time and
+synchronous form of communication: there is another user actively waiting on you to respond.
+Calendar events are another good example of when to use a notification and grab the user's
+attention, because the event is imminent, and calendar events often involve other people.</p>

+
+<h4>When not to display a notification</h4>
+<p>There are however many other cases where notifications should not be used:</p>
+<ul>
+<li>
+<p>Don't notify the user of information that is not directed specifically at them, or information
+that is not truly time sensitive. For instance the asynchronous and undirected updates flowing
+through a social network do not warrant a real time interruption.</p>
+</li>
+<li>
+<p>Don't create a notification if the relevant new information is currently on screen. Instead, use
+the UI of the application itself to notify the user of new information directly in context. For
+instance, a chat application should not create system notifications while the user is actively
+chatting with another user.</p>
+</li>
+<li>
+<p>Don't interrupt the user for low level technical operations, like saving or syncing information,
+or updating an application, if it is possible for the system to simply take care of itself without
+involving the user.</p>
+</li>
+<li>
+<p>Don't interrupt the user to inform them of an error if it is possible for the application to
+quickly recover from the error on its own without the user taking any action.</p>
+</li>
+<li>
+<p>Don't use notifications for services that the user cannot manually start or stop.</p>
+</li>
+<li>
+<p>Don't create superfluous notifications just to get your brand in front of users. Such
+notifications will only frustrate and likely alienate your audience. The best way to provide the
+user with a small amount of updated information and to keep them engaged with your application is to
+develop a widget that they can choose to place on their home screen.</p>

+<h2>Design Guidelines</h2>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-6">
+
+ <img src="../static/content/notifications_pattern_anatomy.png">
+
+ </div>
+ <div class="layout-content-col span-6">
+
+<h4>Make it personal</h4>
+<p>For notifications of items sent by another user (such as a message or status update), include that
+person's image.</p>
+<p>Remember to include the app icon as a secondary icon in the notification, so that the user can
+still identify which app posted it.</p>
+
+ </div>
+</div>
+
+<h4>Navigate to the right place</h4>
+<p>When the user touches a notification, be open your app to the place where the user can consume and
+act upon the data referenced in the notification. In most cases this will be the detail view of a
+single data item (e.g. a message), but it might also be a summary view if the notification is
+stacked (see <em>Stacked notifications</em> below) and references multiple items. If in any of those cases
+the user is taken to a hierarchy level below your app's top-level, insert navigation into your app's
+back stack to allow them to navigate to your app's top level using the system back key. For more
+information, see the chapter on <em>System-to-app navigation</em> in the
+<a href="../patterns/notifications.html">Navigation</a> design pattern.</p>
+<h4>Timestamps for time sensitive events</h4>
+<p>By default, standard Android notifications include a timestamp in the upper right corner. Consider
+whether the timestamp is valuable in the context of your notification. If the timestamp is not
+valuable, consider if the event is important enough to warrant grabbing the user's attention with a
+notification. If the notification is important enough, decide if you would like to opt out of
+displaying the timestamp.</p>
+<p>Include a timestamp if the user likely needs to know how long ago the notification occurred. Good
+candidates for timestamps include communication notifications (email, messaging, chat, voicemail)
+where the user may need the timestamp information to understand the context of a message or to
+tailor a response.</p>
+<h4>Stack your notifications</h4>
+<p>If your app creates a notification while another of the same type is still pending, avoid creating
+an altogether new notification object. Instead, stack the notification.</p>
+<p>A stacked notification builds a summary description and allows the user to understand how many
+notifications of a particular kind are pending.</p>
+<p><strong>Don't</strong>:</p>
+
+<img src="../static/content/notifications_pattern_additional_fail.png">
+
+<p><strong>Do</strong>:</p>
+
+<img src="../static/content/notifications_pattern_additional_win.png">
+
+<p>If you keep the summary and detail information on different screens, a stacked notification may need
+to open to a different place in the app than a single notification.</p>
+<p>For example, a single email notification should always open to the content of the email, whereas a
+stacked email notification opens to the Inbox view.</p>
+<h4>Clean up after yourself</h4>
+<p>Just like calendar events, some notifications alert the user to an event that happens at a
+particular point in time. After that moment has passed, the notification is likely not important to
+the user anymore, and you should consider removing it automatically. The same is true for active
+chat conversations or voicemail messages the user has listened to, users should not have to manually
+dismiss notifications independently from taking action on them.</p>
+
+<div class="vspace size-1">&nbsp;</div>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-7">
+
+<h4>Provide a peek into your notification</h4>
+<p>You can provide a short preview of your notification's content by providing optional ticker text.
+The ticker text is shown for a short amount of time when the notification enters the system and then
+hides automatically.</p>
+
+ </div>
+ <div class="layout-content-col span-6">
+
+ <img src="../static/content/notifications_pattern_phone_ticker.png">
+
+ </div>
+</div>
+
+<h4>Make notifications optional</h4>
+<p>Users should always be in control of notifications. Allow the user to silence the notifications from
+your app by adding a notification settings item to your application settings.</p>
+<h4>Use distinct icons</h4>
+<p>By glancing at the notification area, the user should be able to discern what notification types are
+currently pending.</p>
+<p><strong>Do</strong>:</p>
+<ul>
+<li>Look at the notification icons the Android apps already provide and create notification icons for
+ your app that are sufficiently distinct in appearance.</li>
+</ul>
+<p><strong>Don't</strong>:</p>
+<ul>
+<li>Use color to distinguish your app from others. Notification icons should generally be monochrome.</li>

+
+<p>Notifications are indicated by icons in the notification area and can be accessed by opening the
+notification drawer.</p>
+<p>Inside the drawer, notifications are chronologically sorted with the latest one on top. Touching a

+<h4>Ongoing notifications</h4>
+<p>Ongoing notifications keep users informed about an ongoing process in the background. For example,
+music players announce the currently playing track in the notification system and continue to do so
+until the user stops the playback. They can also be used to show the user feedback for longer tasks
+like downloading a file, or encoding a video. Ongoing notifications cannot be manually removed from

+<h4>Dialogs and toasts are for feedback not notification</h4>
+<p>Your app should not create a dialog or toast if it is not currently on screen. Dialogs and Toasts
+should only be displayed as the immediate response to the user taking an action inside of your app.
+For instance, dialogs can be used to confirm that the user understands the severity of an action,
+and toasts can echo back that an action has been successfully taken.</p>

+<p>Most developers want to distribute their apps on multiple platforms. As you plan your app for
+Android, keep in mind that different platforms play by different rules and conventions. Design
+decisions that make perfect sense on one platform will look and feel misplaced in the context of a
+different platform. While a "design once, ship anywhere" approach might save you time up-front, you
+run the very real risk of creating inconsistent apps that alienate users. Consider the following
+guidelines to avoid the most common traps and pitfalls.</p>

+<h4>Don't mimic UI elements from other platforms</h4>
+<p>Platforms typically provide a carefully designed set of UI elements that are themed in a very
+distinctive fashion. For example, some platforms advocate rounded corners for their buttons, others
+use gradients in their title bars. In some cases, elements may have the same purpose, but are
+designed to work a bit differently.</p>
+<p>As you build your app for Android, don't carry over themed UI elements from other platforms and
+don't mimic their specific behaviors. Review the <a href="../building-
+blocks/index.html">Building Blocks</a> section in this styleguide to learn about Android's most important UI elements
+and the way they look in the system default themes. Also examine Android's platform apps to get a
+sense of how elements are applied in the context of an app. If you want to customize the theme of UI
+elements, customize carefully according to your specific branding - and not according to the
+conventions of a different platform.</p>

+counterparts.</p>

+addition, Android apps may use a bottom bar to display actions on a split action bar.</p>
+<p>You should follow this guideline to create a consistent experience with other apps on the Android
+platform and to avoid confusion between actions and view switching on Android.</p>

+navigation and the navigation bar's back button for temporal navigation. For more information,
+please review the <a href="../patterns/navigation.html">Navigation</a> pattern.</p>

+<p>Android does not use such indicators on drill-down line items. Avoid them to stay consistent with
+the platform and in order to not have the user guess as to what the meaning of those carets may be.</p>

+<h2>Device Independence</h2>
+
+<p>Remember that your app will run on a wide variety of different screen sizes. Create visual assets
+for different screen sizes and densities and make use of concepts such as multi-pane layouts to
+appropriately scale your UI on different device form factors.</p>

+<p>Android 3.0 introduced the <em>long press</em> gesture&mdash;that is, a touch that's held in the same
+position for a moment&mdash;as the global gesture to select data. This affects the way you should
+handle multi-select and contextual actions in your apps.</p>
+
+<div class="vspace size-1">&nbsp;</div>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-6">
+
+<h4>What has changed?</h4>
+<p>In previous versions of Android, the long press gesture was universally used to display contextual
+actions for a given data item in a contextual menu.</p>
+<p>This pattern changed with Android 3.0. The long press gesture is now used to select data, combining
+contextual actions and selection management functions for selected data into a new element called
+the contextual action bar (CAB).</p>

+ Traditional use of the long press gesture to show contextual menus.
+ </div>
+
+ </div>
+</div>
+
+<h4>Using the contextual action bar (CAB)</h4>
+<p>The selection CAB is a temporary action bar that overlays your app's current action bar while data
+is selected. It appears after the user long presses on a selectable data item.</p>
+
+<img src="../static/content/selection_cab_big.png">
+
+<div class="vspace size-1">&nbsp;</div>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-6">
+
+<p>From here the user can:</p>
+<ul>
+<li>Select additional data items by touching them.</li>
+<li>Trigger an action from the CAB that applies to all highlighted data items. The CAB then
+ automatically dismisses itself.</li>
+<li>Dismiss the CAB via the navigation bar's Back button or the CAB's checkmark button. This removes
+ the CAB along with all selection highlights.</li>
+</ul>

+</div>
+
+<div class="layout-content-row">
+ <div class="layout-content-col span-6">
+
+<h4>Selecting CAB actions</h4>
+<p>You can decide which actions and elements appear in the CAB. Use the guidelines in the <a href="actionbar.html">Action Bar
+pattern</a> to decide which items to surface at the top level and which to move to the
+action overflow.</p>
+<h4>Dynamically adjust CAB actions</h4>
+<p>In most cases you need to adjust the actions in the CAB dynamically as the user adds more items to
+the selection. Actions that apply to a single selected data item don't necessarily apply to multiple
+selected data items of the same kind.</p>

+
+<h2>Checklist</h2>
+<ul>
+<li>
+<p>Whenever your app supports the selection of multiple data items, make use of the contextual action
+ bar (CAB).</p>
+</li>
+<li>
+<p>Reserve the long press gesture for selection exclusively. Don't use it to display traditional
+ contextual menus.</p>
+</li>
+<li>
+<p>If you don't support multi-selection within a list, long press should do nothing.</p>
+</li>
+<li>
+<p>Plan the actions you want to display inside of a CAB in the same way you would plan the actions
+ inside your app's action bar.</p>
+</li>

+<p>Efficient navigation is one of the cornerstones of a well-designed app. While apps are generally
+built in a hierarchical fashion, there are instances where horizontal navigation can flatten
+vertical hierarchies and make access to related data items faster and more enjoyable. Swipe views
+allow the user to efficiently move from item to item using a simple gesture and thereby make
+browsing and consuming data a more fluent experience.</p>
+<h2>Swiping Between Detail Views</h2>
+<p>An app's data is often organized in a master/detail relationship: The user can view a list of
+related data items, such as images, chats, or emails, and then pick one of the items to see the
+detail contents in a separate screen.</p>
+
+<img src="../static/content/swipe_views.png">
+<div class="figure-caption">
+ Master (left) and detail (right) views.
+</div>
+
+<p>On a phone, since the master and detail are on separate screens, this typically requires the user to
+jump back and forth between the list and the detail view, aka "pogo-sticking".</p>
+<p>In cases where users will want to view multiple detail items in succession, avoid pogo-sticking by
+using the swipe gesture to navigate to the next/previous detail view.</p>

+<p>Use swipe to quickly navigate between detail views or tabs.</p>
