Includes updates to the features doc, to reflect the v4 support library's division into several smaller modules. Also modified the transitions doc to note the support library's support for transitions in API levels 14-19. Since we're deprecating support for API levels below 9, I changed several examples to use higher API levels. See first comment for doc stage location. bug: 30505601 Change-Id: Ic06a023f705893c91ff3b86d0af8cfed957eb724

<p>The user interface of an activity often changes in response to user input and other events.
|
|
For example, an activity that contains a form where users can type search queries can hide
|
|
the form when the user submits it and show a list of search results in its place.</p>
|
|
|
|
<p>To provide visual continuity in these situations, you can animate changes between
|
|
different view hierarchies in your user interface. These animations give users feedback on
|
|
their actions and help them learn how your app works.</p>
|
|
|
|
<p>Android includes the <em>transitions framework</em>, which enables you to easily
|
|
animate changes between two view hierarchies. The framework animates the views at runtime by
|
|
changing some of their property values over time. The framework includes built-in animations
|
|
for common effects and lets you create custom animations and transition lifecycle callbacks.</p>
|
|
|
|
<p>This class teaches you to use the built-in animations in the transitions framework to
|
|
animate changes between view hierarchies. This class also covers how to create custom
|
|
animations.</p>

<p class="note"><strong>Note:</strong> For Android versions earlier than 4.4.2 (API level 19)
|
|
but greater than or equal to Android 4.0 (API level 14), use the Android Support
|
|
Library's <a href="/reference/android/support/transitions/package-summary.html"
|
|
><code>android.support.transition</code></a> package.</p>
