PiP is a 64special type of [multi-window][1] mode mostly used for video playback. PiP mode is already available 65for [Android TV][2]; the O Developer Preview makes the feature available on other Android devices. 66 67The app is *paused* when it enters PiP mode, but it should continue showing content. For this 68reason, you should make sure your app does not pause playback in its [onPause()][3] 69handler. Instead, you should pause video in [onStop()][4]. For more information, see [Multi-Window 70Lifecycle][5]. 71 72To specify that your activity can use PIP mode, set `android:supportsPictureInPicture` to `true` in 73the manifest. (Beginning with the O Developer Preview, you do not need to set 74`android:resizeableActivity` to `true` if you are supporting PIP mode, either on Android TV or on 75other Android devices; you only need to `setrandroid:resizeableActivity` if your activity supports 76other multi-window modes.) 77 78You can pass a [PictureInPictureArgs][6] to [enterPictureInPictureMode()][7] to specify how an 79activity should behave when it is in PiP mode. You can also use it to call 80[setPictureInPictureArgs()][8] and update the current behavior. If the app is in not PiP mode, it 81will be used for later call of [enterPictureInPictureMode()][7]. 82 83With a [PictureInPictureArgs][6], you can specify aspect ratio of PiP activity and action items 84available for PiP mode. The aspect ratio is used when the activity is in PiP mode. The action items 85are used as menu items in PiP mode. You can use a [PendingIntent][9] to specify what to do when the 86item is selected. 87 88[1]: https://developer.android.com/guide/topics/ui/multi-window.html 89[2]: https://developer.android.com/training/tv/playback/picture-in-picture.html 90[3]: https://developer.android.com/reference/android/app/Activity.html#onPause() 91[4]: https://developer.android.com/reference/android/app/Activity.html#onStop() 92[5]: https://developer.android.com/guide/topics/ui/multi-window.html#lifecycle 93[6]: https://developer.android.com/reference/android/app/PictureInPictureArgs.html 94[7]: https://developer.android.com/reference/android/app/Activity.html#enterPictureInPictureMode(android.app.PictureInPictureArgs) 95[8]: https://developer.android.com/reference/android/app/Activity.html#setPictureInPictureArgs(android.app.PictureInPictureArgs) 96[9]: https://developer.android.com/reference/android/app/PendingIntent.html 97]]> 98 </intro> 99 </metadata> 100 101</sample> 102
