java - Mediastyle 通知在 android 11 中不起作用

Question

我的自定义媒体样式通知不再适用于我的音乐应用的 Android 11。它在 Android 10 和以前的版本中运行良好。
是否需要添加任何其他代码才能在 Android 11 中运行。
我应该补充一点，摆脱“.setMediaSession(mediaSessionCompat.getSessionToken())) ”行会给我一个通知，但它不是具有完整背景颜色的奥利奥通知等。
这是我创建通知的代码:

public static final String CHANNEL_ID = "Channel1";

//public static final String ACTION_PREVIOUS = "actionprevious";
public static final String ACTION_PLAY = "actionplay";
public static final String ACTION_EXIT = "actionexit";
//public static final String ACTION_NEXT = "actionnext";

public static Notification notification;

public static void createNotification(Context context, Track track, int playbutton, int exitApp, int pos, int size) {

    if (Build.VERSION.SDK_INT >=Build.VERSION_CODES.O) {

        NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(context); 
        MediaSessionCompat mediaSessionCompat = new MediaSessionCompat(context, "tag"); /

        mediaSessionCompat.setActive(true);

        Bitmap icon = BitmapFactory.decodeResource(context.getResources(),R.drawable.half); 

        Intent intentPlay = new Intent(context, NotificationActionService.class)
                .setAction(ACTION_PLAY);
        PendingIntent pendingIntentPlay = PendingIntent.getBroadcast(context, 0,
                intentPlay, PendingIntent.FLAG_UPDATE_CURRENT);

        Intent intentExit = new Intent(context, NotificationActionService.class)
                .setAction(ACTION_EXIT);
        PendingIntent pendingIntentExit = PendingIntent.getBroadcast(context, 0,
                intentExit, PendingIntent.FLAG_UPDATE_CURRENT);

        exitApp = R.drawable.ic_close_black;

    
        Intent intentOpenApp = new Intent(context, MainActivity.class);
        PendingIntent pendingIntentOpenApp = PendingIntent.getActivity(context,0,
                intentOpenApp, 0);

      

         Notification.MediaStyle style = new Notification.MediaStyle();
        androidx.core.app.NotificationCompat.Builder builder = new androidx.core.app.NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
                //NotificationCompat.Builder builder = new NotificationCompat.Builder( this, NOTIFICATION_CHANNEL_ID );
                .setSmallIcon(R.drawable.ic_audiotrack)
                .setVisibility(androidx.core.app.NotificationCompat.VISIBILITY_PUBLIC) 
                .setLargeIcon(icon)
                .setContentTitle( "TEST" )
                .setContentText(notificationText)
                .setContentIntent(pendingIntentOpenApp) 
                .setShowWhen(false) 
                .setOngoing(true)           .setBadgeIconType(androidx.core.app.NotificationCompat.BADGE_ICON_NONE) 
                .setOnlyAlertOnce(true)
                .addAction(action)
                .addAction(generateAction(R.drawable.ic_close_black, "Exit", ACTION_EXIT))
                .setStyle(new NotificationCompat.MediaStyle()
                        .setShowActionsInCompactView(0,1)
                        .setMediaSession(mediaSession.getSessionToken())); 


        mediaSession.setMetadata
            (new MediaMetadataCompat.Builder()
                .putBitmap(MediaMetadataCompat.METADATA_KEY_ALBUM_ART,icon)
                .putString(MediaMetadata.METADATA_KEY_TITLE, "TEST TITLE")
                .putString(MediaMetadata.METADATA_KEY_ARTIST, "TEST ARTIST")
                .build()
        );



        startForeground(1, builder.build()); 
    }


}

您现在还需要向媒体 session 添加元数据:

mediaSessionCompat.setMetadata(
    new MediaMetadataCompat.Builder()
        .putString(MediaMetadata.METADATA_KEY_TITLE, track.getTitle())
        .putString(MediaMetadata.METADATA_KEY_ARTIST, track.getArtist())
        .build()
    );
