MediaStyleNotificationHelper.MediaStyle


class MediaStyleNotificationHelper.MediaStyle : NotificationCompat.Style

Known direct subclasses
MediaStyleNotificationHelper.DecoratedMediaCustomViewStyle

Notification style for media custom views that are decorated by the system.


Notification style for media playback notifications.

In the expanded form, up to 5 actions specified with #addAction(int, CharSequence, PendingIntent) addAction will be shown as icon-only pushbuttons, suitable for transport controls. The Bitmap given to #setLargeIcon(android.graphics.Bitmap) setLargeIcon() will be treated as album artwork.

Unlike the other styles provided here, MediaStyle can also modify the standard-size content view; by providing action indices to setShowActionsInCompactView you can promote up to 3 actions to be displayed in the standard view alongside the usual content.

Notifications created with MediaStyle will have their category set to CATEGORY_TRANSPORT unless you set a different category using setCategory().

Finally, the System UI can identify this as a notification representing an active media session and respond accordingly (by showing album artwork in the lockscreen, for example).

To use this style with your Notification, feed it to setStyle like so:

Notification noti = new NotificationCompat.Builder()
    .setSmallIcon(androidx.media3.R.drawable.media3_notification_small_icon)
    .setContentTitle("Track title")
    .setContentText("Artist - Album")
    .setLargeIcon(albumArtBitmap)
    .setStyle(new MediaStyleNotificationHelper.MediaStyle(mySession))
    .build();

fun setRemotePlaybackInfo(
    deviceName: CharSequence!,
    iconResource: @DrawableRes Int,
    chipIntent: PendingIntent?
): MediaStyleNotificationHelper.MediaStyle!

For media notifications associated with playback on a remote device, provide device information that will replace the default values for the output switcher chip on the media control, as well as an intent to use when the output switcher chip is tapped, on devices where this is supported.

Most apps should integrate with android.media.MediaRouter2 instead. This method is only intended for system applications to provide information and/or functionality that would otherwise be unavailable to the default output switcher because the media originated on a remote device.

Also note that this method is a no-op when running on API 33 or lower.

Parameters
deviceName: CharSequence!

The name of the remote device to display.

iconResource: @DrawableRes Int

Icon resource, of size 12, representing the device.

chipIntent: PendingIntent?

PendingIntent to send when the output switcher is tapped. May be null, in which case the output switcher will be disabled. This intent should open an android.app.Activity or it will be ignored.

setShowActionsInCompactView

@CanIgnoreReturnValue
fun setShowActionsInCompactView(actions: IntArray!): MediaStyleNotificationHelper.MediaStyle!

Requests up to 3 actions (by index in the order of addition) to be shown in the compact notification view.
