As of Android O, activities can launch in [Picture-in-Picture (PiP)][1] mode. PiP is a
|
|
special type of [multi-window][2] mode mostly used for video playback.
|
|
|
|
The app is *paused* when it enters PiP mode, but it should continue showing content. For this
|
|
reason, you should make sure your app does not pause playback in its [onPause()][3]
|
|
handler. Instead, you should pause video in [onStop()][4]. For more information, see [Multi-Window
|
|
Lifecycle][5].
|
|
|
|
To specify that your activity can use PIP mode, set `android:supportsPictureInPicture` to `true` in
|
|
the manifest. (Beginning with Android O, you do not need to set
|
|
`android:resizeableActivity` to `true` if you are supporting PIP mode you only need to
|
|
`setrandroid:resizeableActivity` if your activity supports other multi-window modes.)
|
|
|
|
You can pass a [PictureInPictureParams][6] to [enterPictureInPictureMode()][7] to specify how an
|
|
activity should behave when it is in PiP mode. You can also use it to call
|
|
[setPictureInPictureParams()][8] and update the current behavior. If the app is in not PiP mode, it
|
|
will be used for later call of [enterPictureInPictureMode()][7].
|
|
|
|
With a [PictureInPictureParams][6], you can specify aspect ratio of PiP activity and action items
|
|
available for PiP mode. The aspect ratio is used when the activity is in PiP mode. The action items
|
|
are used as menu items in PiP mode. You can use a [PendingIntent][9] to specify what to do when the
|
|
item is selected.
