<p>Android Development Tools (ADT) is a plugin for the Eclipse IDE
that is designed to give you a powerful, integrated environment in which
to build Android applications.</p>

<p>ADT extends the capabilities of Eclipse to let you quickly set up new Android
projects, create an application UI, add packages based on the Android
Framework API, debug your applications using the Android SDK tools, and even
export signed (or unsigned) {@code .apk} files in order to distribute your application.</p>

<p>Developing in Eclipse with ADT is highly recommended and is the fastest way
to get started. With the guided project setup it provides, as well as tools
integration, custom XML editors, and debug output pane, ADT gives you an
incredible boost in developing Android applications. </p>

<p>This document provides step-by-step instructions on how to download the ADT
plugin and install it into your Eclipse development environment. Note that
before you can install or use ADT, you must have compatible versions of both the
Eclipse IDE and the Android SDK installed. For details, make sure to read <a
href="{@docRoot}sdk/installing/installing-adt.html">Installing the Eclipse
Plugin</a>. </p>

<p>If you are already using ADT, this document also provides instructions on
how to update ADT to the latest version or how to uninstall it, if necessary.
</p>

<p>For information about the features provided by the ADT plugin, such as code
editor features, SDK tool integration, and the graphical layout editor (for drag-and-drop layout
editing), see the <a href="{@docRoot}tools/help/adt.html">Android Developer Tools</a>
document.</p>


<h2 id="notes">Revisions</h2>

<p>The sections below provide notes about successive releases of
the ADT Plugin, as denoted by revision number. </p>

    <ul>
      <li>Updated tools to allow libraries to share the same package name as the applications
        that use them.</li>
      <li>Added new Lint checks, including checks for layout consistency,
        {@link android.widget.RelativeLayout} siblings, {@link android.os.Parcel} creator,
        JavaScript interfaces, {@link android.app.Service} casting, quantity strings, manifest
        typos, orientation tags in layouts, overlapping names for 9-patches and images, and class

  <dt>General Notes:</dt>
  <dd>
    <ul>
      <li>Added new <a href="{@docRoot}tools/projects/templates.html">code templates</a> for
        notifications, blank fragments and list fragments.</li>
      <li>Added support for resource rename refactoring. Renaming a resource XML file, drawable
        icon, an {@code R.} field name or ID in the layout editor invokes a refactoring routine
        to update all resource references.</li>
      <li>Added more than 15 new Lint checks, including checks for overriding older APIs, XML
        resource problems, graphic asset issues and manifest tags.
      <li>Updated XML Editor to respond to refactoring shortcut keys such as <strong>Refactor
        &gt; Rename</strong>.</li>
      <li>Updated XML Editor to improve double click handling.</li>
      <li>Added code completion improvements for custom views, theme references and class
        references. For example, code completion in a {@code &lt;fragment android:name=””&gt;} tag
        now suggests completion with a list of fragment classes. Similarly, code completion in the
        manifest now offers implementations suitable for the given tag.</li>
      <li>Updated the <strong>Project Import</strong> dialog so that it shows a table for all
        imported projects where you can edit the name of the imported project.</li>
      <li>Added support for layout aliases in the Layout Editor.</li>

        <ul>
          <li>Updated build to detect and handle package name conflicts between an application and
            the libraries it depends on. Libraries cannot share package names unless all of them
            share the same package name.

          <li>Added a flag to disable dex merging to deal with cases where merging could generate
            a broken dex file. If this happens to your project, add the following setting to your
            {@code project.properties} file: {@code dex.disable.merger=true} This setting
            causes the build system to revert to the older, slower dex processing that does not
            pre-dex libraries.</li>

    </ul>
  </dd>

  <dt>General improvements:</dt>
  <dd>
    <ul>
      <li>Layout Editor
        <ul>
          <li>Added multi-configuration editing feature that was previewed at Google I/O
            developer tools talk in June. For an overview, see the
            <a href="https://www.youtube.com/watch?v=Erd2k6EKxCQ">session recording</a>
            (starting at: 20:30).</li>
          <li>Modified the layout logic so that setting a {@link android.app.Fragment} layout or
            a {@link android.widget.ListView} preview layout is now applied not
            only to the current layout but to all other configurations of the same layout.</li>
          <li>Updated the editor to include resources from library projects in the resource chooser,
            XML code completion, Go To Declaration and other editing contexts.</li>
          <li>Updated the editor so that it  no longer forces all variations of a single
            layout into a single editor. You can, for example, open both the landscape and portrait
            versions of a layout as separate editors and quickly switch between them, or even
            re-dock your editors to edit them simultaneously. If you prefer the previous behavior,
            set the new option in <strong>Preferences &gt; Android &gt; Editors</strong> to use the
            old behavior.</li>
          <li>Improved the handling of {@link android.widget.RelativeLayout} in the layout editor,
            so that dragging widgets around and deleting them should now result in the layout
            working more intuitively. In particular, deleting a widget causes the constraints
            flowing through the deleted widgets to be intelligently adjusted, and when moving
            widgets the constraints are preserved whenever possible.</li>
          <li>Added the ability to specify a default action in Layout Editor views, which you can
            invoke with the <em>F2</em> key. For example, after dropping a button or text view,
            you can press <em>F2</em> to edit its text.</li>
          <li>Added renaming of an ID (changing the {@code android:id} attribute) by invoking the
            <strong>Rename</strong> shortcut.</li>
          <li>Adding a new locale is now easier with the new <strong>Add Locale...</strong> action
            in the locale menu. In addition to creating the new values folder, it lets you edit an
            initial set of translations for the new locale.</li>
          <li>Updated the editor so that when a custom view (or incorrectly configured view)
            throws an exception during initialization or painting, part of the relevant stack trace
            is shown inline in the layout editor, and you can click on the stack frames to jump to
            the relevant location</li>
          <li>Improved the editor error display to show the relevant part of a stack trace
            when a custom view throws exceptions during rendering or construction, and provides
            hyperlinks to the stack frames.</li>
          <li>Improved the stack trace display for exceptions for custom views that are generated
            during rendering.</li>
          <li>Updated the configuration chooser so that it shows full language and region names (not
            just 2-letter codes) in menus, in the configuration dialog and other editing contexts.
            </li>
          <li>Improved the device menu in the configuration chooser.</li>
        </ul>
      </li>
      <li>Lint
        <ul>
          <li>Added over 25 new lint rules for resources, locale settings, layout
            files, incorrect use of {@link android.util.SparseArray} and
            {@link android.os.PowerManager.WakeLock} and manifest issues.</li>
          <li>Improved the XML export function to support the
            <a href="https://wiki.jenkins-ci.org/display/JENKINS/Android+Lint+Plugin">Jenkins Lint
            plugin</a>.
          </li>
        </ul>
      </li>
      <li>Editors
        <ul>
          <li>Modified the plugin to remember which editor mode (text or graphical) you were last
            using for each type of editor (layout, manifest or values) and uses that mode for newly
            opened files. This means that if you prefer to work with just XML, the editors start
            showing you XML text editors after you have switched to them for each type of editor.</li>
          <li>Updated XML code completion so that it completes (and shows documentation for) theme
            references, such as {@code ?android:attr/dividerHeight}.</li>
        </ul>
      </li>
      <li>Android Virtual Devices (AVD)
        <ul>
          <li>Added new <strong>Device Definitions</strong> tab in the AVD Manager for configuring
            standard size and Nexus virtual devices.</li>
          <li>Improved emulators so that they launch with a skin that is dynamically generated and
            reflects the actual hardware configured in the AVD Manager.</li>
        </ul>
      </li>
      <li>Improved the new template mechanism, cleaned up the existing templates and added
        several new templates</li>
      <li>Added ability to export images and frames in the Tracer for OpenGL ES tool.</li>
      <li>Integrated the Systrace tool into the DDMS perspective.</li>
      <li>Improved the JUnit test runner to allow a test to be run on all connected devices
        simultaneously.</li>
    </ul>
  </dd>

  <dt>Bug fixes:</dt>
  <dd>
    <ul>
      <li>Fixed the editors so that attributes and resources specified by XML files in the
        {@code /values} directory are validated when files are saved.</li>
      <li>Added a workaround for a bug in Eclipse on Mac OS X 10.8 where the Property Sheet was not
        working properly.</li>

        </ul>
      </li>
      <li>Performance
        <ul>

      </li>
      <li>Tracer for GLES
        <ul>
          <li>Added new perspective view and tools for tracing OpenGL calls for an application and
track the visual results of each call. (<a href="{@docRoot}tools/help/gltracer.html">more info</a>)</li>
        </ul>
      </li>
      <li>Lint
        <ul>
          <li>Added new Lint rules for manifest registrations, duplicate activity
registrations, security checking, correct use of Toast, missing SharedPreferences commit()
calls, Fragment class instantiation, and handler leaks.</li>
          <li>Created tighter integration of lint with the layout editor. (<a
href="http://tools.android.com/recent/lintfeedback">more info</a>)</li>
          <li>Added execution of Lint tool on save option for Java files. (<a

        </ul>
      </li>
      <li>Layout Editor (<a href="http://tools.android.com/recent/newlayouteditorpropertysheet">more
info</a>)
        <ul>
          <li>Added highlighting (in bold) for important attributes, inline preview of colors and
images, including the corresponding resource name.</li>
          <li>Added display of default values, when available.</li>
          <li>Added completion of resource values and enum and flag constants.</li>
          <li>Added support for displaying advanced properties, and nested properties for better
categorization, for example, layout params are listed first as a single nested property.</li>
          <li>Display Tooltips over the attribute names, not values, so they never obscure the value
column.</li>
          <li>Provided checkbox support for boolean values.</li>
          <li>Added support for switching between alphabetical and natural sort orders.</li>
          <li>Improved layout editor tool's window management for more usable editing views.</li>

      </li>
      <li>XML Editing

          <li>Added go to declaration support for theme references (?android:attr, ?attr:).</li>
          <li>Improved code completion in style definitions.</li>
          <li>Improved code completion for the {@code minSdkVersion} and {@code targetSdkVersion}
attributes in manifest files so that version descriptions are displayed for each of the API
levels</li>
          <li>Provided support for code completion of custom attributes for custom views,
including current edits to the style files.</li>
          <li>Improved synchronization of text and graphic editors with the XML outline view,
including outline changes and display of current selection.</li>
        </ul>
      </li>
      <li>Build System
        <ul>
          <li>Added automatic merging of library project manifest files into the including
project's manifest. Enable this feature with the {@code manifestmerger.enabled} property.</li>
          <li>Added automatic ProGuard support for the {@code aapt -G} flag. This change causes
the build system to generate a temporary ProGuard keep-rules file containing classes that
are referenced from XML files (such as custom views) and pass this to ProGuard at shrink-time. This
can make the resulting APK much smaller when using just a small portion of a large library project
(such as the Android Support library), since the catch-all rules to keep all custom views from the
default ProGuard configuration file have also been removed.</li>
        </ul>
      </li>
      <li>Added support building and debugging NDK-based Android projects.</li>
      </li>
      <li>Added support to the Asset Studio Wizard for padding and turning off background
shapes.</li>
      <li>Improved LogCat to allow developers to set colors for different priorities.</li>
      <li>Improved app Run functionality to allow running on multiple devices with a single launch.
The target tab in the launch configuration dialog includes an option to allow launching on all
connected devices, with the option to further narrow the list to just physical devices or just
emulators. (This feature is available only for Run configurations, and not for Debug or JUnit
tests.)</li>

  <dt>General improvements:</dt>
  <dd>
    <ul>
      <li>New build features
        <ul>
          <li>Added feature to automatically setup JAR dependencies. Any {@code .jar} files in the
          {@code /libs} folder are added to the build configuration (similar to how the Ant build
          system works). Also, {@code .jar} files needed by library projects are also automatically
          added to projects that depend on those library projects.
          (<a href="http://tools.android.com/recent/dealingwithdependenciesinandroidprojects">more
          info</a>)</li>
          <li>Added a feature that allows you to run some code only in debug mode. Builds now
generate a class called {@code BuildConfig} containing a {@code DEBUG} constant that is
automatically set according to your build type. You can check the ({@code BuildConfig.DEBUG})
constant in your code to run debug-only functions.</li>
          <li>Added support for custom views with custom attributes in libraries. Layouts using
custom attributes must use the namespace URI {@code http://schemas.android.com/apk/res-auto} instead
of the URI that includes the app package name. This URI is replaced with the app specific one at
build time.</li>
        </ul>
      </li>
      <li>Improved Lint features. See the <a href="{@docRoot}tools/sdk/tools-notes.html">SDK Tools r17</a>
release notes.</li>
      <li>Improved the Lint user interface
        <ul>
          <li>Added <strong>Run Lint</strong> toolbar action with a dropdown menu for selecting
specific (or all) projects, clearing results and other actions.</li>
          <li>Updated the results window to be organized as a tree rather than a flat list. Each
issue type has a single top level item, which makes it easier to quickly scan through the reported
issues and narrow down to the issues you are most interested in.</li>
          <li>Added many new toolbar actions to the results window, including expand/collapse,
ignore in file, ignore in project, ignore everywhere, show options, and configure columns.</li>
          <li>Added new column options for the <strong>Lint Warnings</strong> tab, such as
category, priority, project, file and line. The column selection (as well as the column sizes) are
persisted. You can also click on columns to sort by those values.</li>
          <li>Added Enable All and Disable All buttons to the Lint Options dialog, and a search
filter textbox to filter by issue id, summary and severity.</li>
        </ul>
      </li>
      <li>Added Quick Outline for XML editors (Ctrl-O, Command-O). This feature shows the structure
of the current file including icons and ids, lets you filter and quickly jump to specific ids.</li>
      <li>Updated the resource chooser to shows the resolved value for resources. For example,
when selecting {@code @string/hello} the chooser displays a resolved value such as "Hello World").
The resource chooser also now allows you to edit the chosen value directly.</li>
      <li>Updated Layout Editor so that it does not assign default ids to layouts, includes and
merge tags. This behavior tended to pollute the namespace with a lot of unused resources since
layouts are not usually manipulated via code, or referenced from XML. (The RelativeLayout editor
automatically assigns ids to views without ids when pointing to them.)</li>
      <li>Added ability to export screenshots from the Layout Editor</li>

      <li>Fixed an issue where dex complains about duplicate classes in cases where a Library
        Project depends on the same jar files or Java-only projects.</li>
      <li>Fixed an issue where test projects had to independently reference the library projects
        used by an app project. Now referencing only the app project is enough.</li>

<li>Revamped the SDK Manager UI (<a href="http://tools.android.com/recent/newsdkmanager">more

(<a href="http://tools.android.com/recent/revampedwizards">more info</a>).</li>
<li>Removed the dependency on Eclipse GEF.</li>

<dt>XML and Java editors:</dt>

   attributes to follow a recommended order and processes any changes made in the Layout editor.
(<a href="http://tools.android.com/recent/xmlformatter">more info</a>).</li>
  <li>Added the "Go to Matching" (Ctrl-Shift-P) feature, which lets you jump
between opening and closing tags in XML files.</li>
  <li>Added support for the "Select Enclosing Element" feature on Mac.</li>
  <li>Added a Quickfix for extracting Strings when the caret is inside a String (<a href="">see

<dt>Visual Refactoring:</dt>
<dd>
  <ul>
    <li>"Extract Style" feature pulls out style-related attributes from your layout and extracts
them as a new style defined in {@code styles.xml} (<a
href="http://tools.android.com/recent/extractstylerefactoring">more info</a>).</li>
    <li>"Wrap in Container" feature lets you select a group of views then surround them
    in a new layout (a new view group, such as a LinearLayout), and transfers namespace and layout
    parameters to the new parent (<a
href="http://tools.android.com/recent/newrefactoringswrapinchangelayoutchangewidget">more
info</a>).</li>
    <li>"Change Layout" feature changes layouts from one type
    to another, and can also flatten a layout hierarchy (<a
href="http://tools.android.com/recent/newrefactoringswrapinchangelayoutchangewidget">more
info</a>).</li>
    <li>"Change Widget Type" feature changes the type of the
    selected views to a new type. Also, a new selection context menu
    in the visual layout editor makes it easy to select siblings as
    well as views anywhere in the layout that have the same type (<a
href="http://tools.android.com/recent/newrefactoringswrapinchangelayoutchangewidget">more
info</a>).</li>
    <li>"Extract as Include" feature finds identical collections of views
    in other layouts and offers to combine them into a single layout that you can then include in
 each layout (<a
href="http://tools.android.com/recent/extractasincludeimprovements">more info</a>).</li>
    <li>Quick Assistant in Eclipse can be invoked
    from the XML editor (with Ctrl-1) to apply any of the above
    refactorings (and Extract String) to the current selection (<a
href="http://tools.android.com/recent/refactoringquickassistant">more info</a>).</li>
  </ul>
</dd>

<dt>Visual Layout Editor:</dt>
<dd>
  <ul>
    <li>This is the update to the layout editor you've been waiting for! It includes (almost) all
the goodies demonstrated at Google I/O. <a href="http://www.youtube.com/watch?v=Oq05KqjXTvs">Watch
the video</a> on YouTube.</li>
    <li>The palette now supports different configurations for supported widgets. That is, a single
view is presented in various different configurations that you can drag into your layout. For
example, there is a <em>Text Fields</em> palette category where you can drag an {@link
android.widget.EditText} widget in as a password field, an e-mail field, a phone field, or other
types of text boxes. Similarly, {@link android.widget.TextView} widgets are preconfigured
with large, normal and small theme sizes, and {@link android.widget.LinearLayout} elements are
preconfigured in horizontal and vertical configurations (<a
href="http://tools.android.com/recent/multipletextfieldandlayouttypes">more info</a>).</li>
    <li>The palette supports custom views. You can pick up any custom
    implementations of the View class you've created in your project or from included libraries and
drag them into your layout (<a
href="http://tools.android.com/recent/customviewsinthepalette">more info</a>).</li>
    <li>Fragments are available in the palette for placement in your layout. In the tool, you can
choose which layout to show rendered for a given fragment tag. Go to declaration works for fragment
classes (<a href="http://tools.android.com/recent/fragmentsupport">more info</a>).</li>
    <li>The layout editor automatically applies a "zoom to fit" for newly
    opened files as well as on device size and orientation changes to
    ensure that large layouts are always fully visible unless you
    manually zoom in.</li>
    <li>You can drop in an {@code &lt;include&gt;} element from the palette, which will pop up
    a layout chooser. When you select the layout to include, it is added with an {@code
&lt;include&gt;}. Similarly, dropping images or image buttons will pop up image
    resource choosers (<a
href="http://tools.android.com/recent/includetagdropsupport">more info</a>).</li>
    <li>The configuration chooser now applies the "Render Target" and
    "Locale" settings project wide, making it trivial to check the
    layouts for different languages or render targets without having
    to configure these individually for each layout.</li>
    <li>The layout editor is smarter about picking a default theme to
    render a layout with, consulting factors like theme registrations
    in the manifest, the SDK version, and other factors.</li>
    <li>The layout editor is smarter about picking a default configuration to render a layout
with, defaulting to the currently visible configuration in the previous file. It also considers the
SDK target to determine whether to default to a tablet or phone screen size.</li>
    <li>Basic focus support. The first text field dropped in a layout is assigned focus, and there
are <strong>Request Focus</strong> and <strong>Clear Focus</strong> context menu items on text
fields to change the focus.</li>
  </ul>
</dd>

<dt>XML editors:</dt>
<dd>
<ul>
  <li>Code completion has been significantly improved. It now works
  with {@code &lt;style&gt;} elements, completes dimensional units,
  sorts resource paths in values based on the attribute name, and more. There are also many fixes to
handle text replacement (<a
href="http://tools.android.com/recent/xmlcodecompletionimprovements">more info</a>).</li>
  <li>AAPT errors are handled better. They are now underlined for the
  relevant range in the editor, and a new quickfix makes it trivial
  to create missing resources.</li>
  <li>Code completion for drawable, animation and color XML files (<a
href="http://tools.android.com/recent/codecompletionfordrawablescolorsandanimationfiles">more
info</a>).</li>
</ul>
</dd>

<dt>DDMS:</dt>
<dd>
<ul>
  <li>"New Folder" action in the File Explorer.</li>
  <li>The screenshot dialog will add timestamps to the filenames and preserve the orientation on
snapshot refresh.</li>
</ul>
</dd>

<dt>General notes:</dt>
<dd>

  <li>A Binary XML editor has been added (<a href="http://tools.android.com/recent/binaryxmleditor">details</a>).</li>
  <li>Traceview is now integrated into the Eclipse UI (<a href="http://tools.android.com/recent/traceviewineclipse">details</a>).</li>
  <li>The "Go To Declaration" feature for XML and <code>.java</code> files quickly show all the matches in the project

  <li>The Resource Chooser can create items such as dimensions, integers, ids, and booleans

        <li>A new Palette with categories and rendering previews
        (<a href="http://tools.android.com/recent/newpalette">details</a>).</li>
        <li>A Layout Actions bar that provides quick access to common layout operations
        (<a href="http://tools.android.com/recent/layoutactionsbar">details</a>).</li>
        <li>When the Android 3.0 rendering library is selected, layouts render more like they do on devices.
        This includes rendering of status and title bars to more accurately reflect the actual
        screen space available to applications
        (<a href="http://tools.android.com/recent/systembarandactionbar">details</a>).</li>

<dt>Dependencies:</dt>

<dd>ADT 9.0.0 is designed for use with SDK Tools r9. If you haven't
already installed SDK Tools r9 into your SDK, use the Android SDK Manager to do

<dt>General notes:</dt>
<dd>
  <ul>
    <li>"Go To Declaration" hyperlink support: You can jump directly from code references (such as
    <code>R.id.main</code>) to the corresponding XML declaration, or from XML attributes (such as
    <code>@string</code>) to the corresponding resource definition, or from manifest XML
    registrations to activities and services.</li>
    <li>Improvements were made to name refactoring.</li>
    <li>AVDs now automatically save their state, so they can restart almost instantly. You can enable this feature when
    creating an AVD or by editing an AVD with the AVD Manager.</li>
    <li>Improvements to the Visual Layout Editor:
      <ul>
        <li>Support for rendering targets: You can now choose an arbitrary Android platform to
        render the current page, regardless of the project's minimum platform. This makes it
        easy to verify the layout and appearance of your activity on different versions of
        the platform.
        </li>
        <li>Improved support for empty and nested layouts: Dragging items over nested and
        invisible layouts automatically enlarges and highlights these layouts, so that they
        can receive drops.
        </li>
        <li>XML formatting improvements: The editor generates cleaner XML and you can now enable
        XML auto-formatting in the <strong>Preferences</strong> menu.</li>
        <li>Improved Outline labels: The Outline tab now displays additional information about each
        View. Textual Views display a snippet of the actual text. Views with a source
        (such as ImageView) displays the resource name. Included Views display the name of the View.
        </li>
        <li>When you right click a View in the Layout Editor,
        the context menu now contains <strong>Edit ID...</strong> and <strong>Edit Text...</strong>
        items. The <strong>Properties...</strong> context menus now list all of the properties and
        provide a way to edit them
        (<a href="http://tools.android.com/recent/editidtextandotherpropertiesviamenu">Details</a>).
        </li>
        <li>The layout editor now properly handles
        <a href="{@docRoot}guide/topics/resources/layout-resource.html#include-element"><code>&lt;include&gt;</code></a>
        and <a href="{@docRoot}guide/topics/resources/layout-resource.html#merge-element"><code>&lt;merge&gt;</code></a>
        tags (<a href="http://tools.android.com/recent/supportforincludeandmerge">Details</a>).</li>
        <li>"Extract as Include" refactoring: The Layout Editor has a new refactoring that allows
        you to select one or more views in a layout, and extract it into a separate layout
        (<a href="http://tools.android.com/recent/extractasincluderefactoring">Details</a>).</li>
        <li>Improved diagnostics for class loading and rendering errors: Class loading and rendering
        error messages are more useful and provide better information about the root cause of the
        error.</li>
        <li>Improved error handling to prevent drag and reordering operations from adding children
        into an {@link android.widget.AdapterView}.</li>
        <li>Outline reordering: Reordering your views in the Outline tab is much easier
        (<a href="http://tools.android.com/recent/outlineimprovements">Details</a>).</li>
        <li>Fix for keybinding bug where keyboard shortcuts did not work (Issues
        <a href="http://code.google.com/p/android/issues/detail?id=13231">13231</a> and
        <a href="http://code.google.com/p/android/issues/detail?id=13134">13134</a>).</li>
        <li>Fix for problems with Custom layout attribute menu (Issue
        <a href="http://code.google.com/p/android/issues/detail?id=13134">13134</a>).</li>
        <li>Automatic configuration for various view types: Certain views have properties configured
        by default. For example, the width of an {@link android.widget.EditText} object is set to
        <code>match_parent</code> when added to a vertical {@link android.widget.LinearLayout}
        or a default image is added to an {@link android.widget.ImageButton}.</li>
        <li>Previews during dragging: Dragging from the palette or dragging within the layout editor
        now shows live previews of the dragged item.</li>
        <li>Navigation improvements: In the Layout Editor, double-clicking Views jumps to the
        corresponding XML element. In the Outline view, double-clicking opens the Properties view.</li>
        <li>The editor has Honeycomb style animation preview support.</li>
        <li>Improved rendering support for various Views (such as TabHosts and SlidingDrawers) in
        Honeycomb (Issues <a href="http://code.google.com/p/android/issues/detail?id=3162">3162</a>
        and <a href="http://code.google.com/p/android/issues/detail?id=13092">13092</a>).</li>
        <li>Included layouts can be rendered and edited in the context of the layouts that include
        them. From a layout using an <a href="{@docRoot}guide/topics/resources/layout-resource.html#include-element">
        <code>&lt;include&gt;</code></a> tag, double-clicking on the
        <a href="{@docRoot}guide/topics/resources/layout-resource.html#include-element">
        <code>&lt;include&gt;</code></a> element edits the referenced layout in the context of the
        current layout. Additionally, when editing a layout that is included by other layouts,
        you can quickly change between context layouts, by right clicking in the editor and choosing
        <strong>Show included in...</strong>. This feature is only available in Honeycomb.</li>
      </ul>
    </li>
    <li>This release fixes many other bugs, but the most important ones are listed below:
  <ul>
   <li>Fixed issue that prevented launching debug builds on productions devices when
    <code>debuggable=true</code> was not set in the Android manifest.</li>
    <li>The LogCat view in DDMS properly handles UTF-8 characters.</li>
    <li>The SDK Manager is more reliable on Windows
    (<a href="http://tools.android.com/recent/sdkmanagerfixes">Details</a>).</li>
    <li>A JUnit initialization bug that prevented you from working with JUnit tests was fixed
    (Issue <a href="http://code.google.com/p/android/issues/detail?id=12411">12411</a>).</li>

<dd>
<ul>
  <li>New version number scheme that follows the SDK Tools revision number. The major version

  <li>Support for true debug build. You no longer need to change the value of the
   <code>debuggable</code> attribute in the Android Manifest.
  <p>Incremental builds automatically insert <code>debuggable="true"</code>, but if you perform
  "export signed/unsigned application package", ADT does <em>not</em> insert it.

  actually create a debug build (it does not remove it if you placed it there).</p></li>
  <li>Automatic <a href="{@docRoot}tools/help/proguard.html">ProGuard</a> support in

<dt>Library projects:</dt>
<dd>
<p>The ADT Plugin now supports the use of <em>library projects</em> during
development, a capability that lets you store shared Android application
code and resources in a separate development project. You can then reference the
library project from other Android projects and, at build time, the tools
compile the shared code and resources as part of the dependent applications.
More information about this feature is available in the <a
href="{@docRoot}tools/projects/index.html#LibraryProjects">Creating and Managing Projects</a> document. </p>
<p>If you are not developing in Eclipse, <a
href="tools-notes.html">SDK Tools r6</a> provides the equivalent library
project support through the Ant build system.</p>

<dt>Dependencies:</dt>

<dd><p>ADT 0.9.6 is designed for use with SDK Tools r5 and later. Before
updating to ADT 0.9.6, we highly recommend that you use the Android SDK Manager to install SDK
Tools r5 into your SDK.</p></dd>

<dt>General Notes:</dt>
<dd>
<ul>
<li>Editing <code>default.properties</code> outside of Eclipse will now
automatically update the project.</li>
<li>Loads the SDK content only when a project requires it. This will make
Eclipse use less resources when the SDK contains many versions of Android.</li>
<li>Resolves potential deadlock between modal dialogs, when launching ADT the
first time with the SDK Usage panel.</li>
<li>Fixes issues with the New Project Wizard when selecting samples.</li>
</ul>
</dd>
<dt>AVD/SDK Manager:</dt>
<dd>
<ul>
<li>Adds support for platform samples packages.</li>
<li>Improves support for dependency between packages.</li>
<li>AVDs now sorted by API level.</li>

<li>Prevents deletion of running AVDs.</li>
</ul>
</dd>
<dt>DDMS:</dt>
<dd>
<ul>
<li>DDMS plug-in now contains the Allocation Tracker view.</li>
<li>New action in the Logcat view: "Go to problem" lets you go directly from an
exception trace output to the code.</li>
</ul>
</dd>
<dt>Editors:</dt>
<dd>
<ul>
<li>Explode mode in the Visual Layout Editor adds a margin to all layout objects
so that it's easier to see embedded or empty layouts.</li>
<li>Outline mode in the Visual Layout Editor draws layout outline to make it
easier to see layout objects.</li>
<li>Several fixes in the configuration selector of the Visual Layout
Editor.</li>
</ul>
</dd>
<dt>Application launching:</dt>
<dd>
<ul>
<li>Applications launched from ADT now behave as if they were clicked from the
Home screen.</li>
<li>Fixes an issue where add-ons without an optional library would not show up as valid
targets for application launches.</li>
<li>Resolves a possible crash when launching applications.</li>
