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> + +<div class="vspace size-1"> </div> + +<div class="layout-content-row"> + <div class="layout-content-col span-5"> + +<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> + + </div> + <div class="layout-content-col span-8"> + + <img src="../static/content/migrating_ui_elements.png"> + <div class="figure-caption"> + Sampling of UI elements from Android, iOS and Windows Phone 7. + </div> + + </div> +</div> + +<div class="vspace size-2"> </div> + +<div class="layout-content-row"> + <div class="layout-content-col span-5"> + +<h4>Don't carry over platform-specific icons</h4> +<p>Platforms typically provide sets of icons for common functionality, such as sharing, creating a new +document or deleting.</p> +<p>As you are migrating your app to Android, please swap out platform-specific icons with their Android +counterparts.</p> +<p>You can find a wide variety of icons for use in your app in the Android SDK.</p> + + </div> + <div class="layout-content-col span-8"> + + <img src="../static/content/migrating_icons.png"> + <div class="figure-caption"> + Sampling of icons from Android, iOS and Windows Phone 7. + </div> + + </div> +</div> + +<div class="vspace size-2"> </div> + +<div class="layout-content-row"> + <div class="layout-content-col span-5"> + +<h4>Don't use bottom tab bars</h4> +<p>Other platforms use the bottom tab bar to switch between the app's views. Per platform convention, +Android's tabs for view control are shown in action bars at the top of the screen instead. In +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> +<p>For more information on how to properly use action bars for view control, see +<a href="../patterns/actionbar.html">Action Bars</a>.</p> + + </div> + <div class="layout-content-col span-8"> + + <img src="../static/content/migrating_ios_dialers.png"> + <div class="figure-caption"> + Android dialer with tabs in an action bar vs. bottom tabs in iOS. + </div> + + </div> +</div> + +<div class="layout-content-row"> + <div class="layout-content-col span-5"> + +<h4>Don't use labeled back buttons on action bars</h4> +<p>Other platforms use an explicit back button with label to allow the user to navigate up the +application's hierarchy. Instead, Android uses the main action bar's app icon for hierarchical +navigation and the navigation bar's back button for temporal navigation.
