<p>Apps can take advantage of vsync timing for free, through Android’s <strong>animation framework</strong>. The animation framework now uses vsync timing to automatically handle synchronization across animators.</p>

<p>For specialized uses, apps can access vsync timing through APIs exposed by a new Choreographer class. Apps can request invalidation on the next vsync frame &mdash; a good way to schedule animation when the app is not using the animation framework. For more advanced uses, apps can post a calllback that the Choreographer class will run on the next frame. </p>

android.app.Activity#onResume()} to initialize components that you release during {@link

<p>The following example of {@link android.app.Activity#onResume()} is the counterpart to

the {@link android.app.Activity#onPause()} example above, so it initializes the camera that's

android.app.Activity#finish()} from within the {@link android.app.Activity#onCreate onCreate()}

method. In some cases, such as when your activity operates as a temporary decision maker to

launch another activity, you might call {@link android.app.Activity#finish()} from within {@link

android.app.Activity#onCreate onCreate()} to destory the activity. In this case, the system

android.app.Activity#onCreate onCreate()} to destroy the activity. In this case, the system

immediately calls {@link android.app.Activity#onDestroy} without calling any of the other

lifecycle methods.</p>
