Mediastyle notifications not working in android 11

问题

以下是您的代码翻译部分：

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(context, NOTIFICATION_CHANNEL_ID)
                //NotificationCompat.Builder builder = new NotificationCompat.Builder(context, NOTIFICATION_CHANNEL_ID);
                .setSmallIcon(R.drawable.ic_audiotrack)

                .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());
    }
}

My custom mediastyle notification no longer works in Android 11 for my music app. It works fine in Android 10 and previous versions.

Is there any other code I need to add so that it works in Android 11.

I should add that getting rid of the " .setMediaSession(mediaSessionCompat.getSessionToken())) " line gives me a notification, but its not an Oreo notification with the full background color, etc.

Here is my code for creating notifications:

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()); 
}
}

你现在还需要向媒体会话添加元数据：

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

You now need to add metadata to your media session as well:

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

我遇到了同样的问题，只有当我将compileSdkVersion设置为30时，我才能解决它。

刚刚遇到了同样的问题。事实证明，对于Mediastyle通知，.setOngoing(true) 似乎无法正常工作。一旦我将其移除，通知就能正确显示。

英文:

Just had the same problem. Turns out .setOngoing(true) doesn't seem to work right with Mediastyle notifications. Once I removed it, the notification showed up correctly.

这有一个简单的解决方法。只需在 mediaSessionCompat 声明后添加以下几行代码。

mediaSessionCompat = new MediaSessionCompat(this, "tag");

mediaSessionCompat.setMetadata(
        new MediaMetadataCompat.Builder()
        .putString(MediaMetadata.METADATA_KEY_TITLE, "歌曲标题")
        .putString(MediaMetadata.METADATA_KEY_ARTIST, "艺术家")
        .build());

希望对你有所帮助。

英文:

There is a simple solution to it. Just add these lines after mediaSessionCompat declaration.

 mediaSessionCompat=new MediaSessionCompat(this,"tag");
mediaSessionCompat.setMetadata(
new MediaMetadataCompat.Builder()
.putString(MediaMetadata.METADATA_KEY_TITLE,"Song Title")
.putString(MediaMetadata.METADATA_KEY_ARTIST,"Artist")
.build());

Hope this helps.

在 setStyle(..) 后添加 mMediaSession.setMetadata(..) ：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    ...
    mBuilder.setStyle(new androidx.media.app.NotificationCompat.MediaStyle()
            .setMediaSession(mMediaSession.getSessionToken())
            .setShowCancelButton(true)
            .setShowActionsInCompactView(0, 1, 2)
            .setCancelButtonIntent(
                    MediaButtonReceiver.buildMediaButtonPendingIntent(
                            context, PlaybackStateCompat.ACTION_STOP)))
            .addAction(new NotificationCompat.Action(
                    R.drawable.ic_noti_previous, "Previous",
                    ppreviousIntent))
            .addAction(new NotificationCompat.Action(
                    R.drawable.ic_noti_pause, "Pause",
                    pplayIntent))
            .addAction(new NotificationCompat.Action(
                    R.drawable.ic_noti_next, "Next",
                    pnextIntent))
            .addAction(new NotificationCompat.Action(
                    R.drawable.ic_noti_close, "Close",
                    pcloseIntent));
    mMediaSession.setMetadata(
        new MediaMetadataCompat.Builder()
            .putString(MediaMetadata.METADATA_KEY_TITLE,"Song Title")
            .putString(MediaMetadata.METADATA_KEY_ARTIST,"Artist")
            .build());
}
else {
    ...
}
英文:

Works for me : Should add "mMediaSession.setMetadata(..)" after setStyle(..)

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
...
mBuilder.setStyle(new androidx.media.app.NotificationCompat.MediaStyle()
.setMediaSession(mMediaSession.getSessionToken())
.setShowCancelButton(true)
.setShowActionsInCompactView(0, 1, 2)
.setCancelButtonIntent(
MediaButtonReceiver.buildMediaButtonPendingIntent(
context, PlaybackStateCompat.ACTION_STOP)))
.addAction(new NotificationCompat.Action(
R.drawable.ic_noti_previous, "Previous",
ppreviousIntent))
.addAction(new NotificationCompat.Action(
R.drawable.ic_noti_pause, "Pause",
pplayIntent))
.addAction(new NotificationCompat.Action(
R.drawable.ic_noti_next, "Next",
pnextIntent))
.addAction(new NotificationCompat.Action(
R.drawable.ic_noti_close, "Close",
pcloseIntent));
mMediaSession.setMetadata(
new MediaMetadataCompat.Builder()
.putString(MediaMetadata.METADATA_KEY_TITLE,"Song Title")
.putString(MediaMetadata.METADATA_KEY_ARTIST,"Artist")
.build());
else
{
...
}
