这是一个可能出现在 Android 13 上的问题。为了解决此问题，您需要强制更新媒体通知封面。请尝试使用以下代码示例：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { 
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID) 
            .setSmallIcon(R.drawable.notification_icon) 
            .setContentTitle("Title") 
            .setContentText("Text") 
            .setLargeIcon(bitmap) 
            .setStyle(new NotificationCompat.MediaStyle() 
                    .setMediaSession(mediaSession.getSessionToken()) 
                    .setShowActionsInCompactView(0, 1, 2 /* #1: pause button */)) 
            .setPriority(NotificationCompat.PRIORITY_HIGH) 
            .setCategory(NotificationCompat.CATEGORY_TRANSPORT); 
    mNotificationManager.notify(NOTIFICATION_ID, builder.build()); 
} else { 
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this) 
            .setSmallIcon(R.drawable.notification_icon) 
            .setContentTitle("Title") 
            .setContentText("Text") 
            .setLargeIcon(bitmap) 
            .setStyle(new NotificationCompat.MediaStyle() 
                    .setMediaSession(mediaSession.getSessionToken()) 
                    .setShowActionsInCompactView(0, 1, 2 /* #1: pause button */)) 
            .setPriority(NotificationCompat.PRIORITY_HIGH) 
            .setCategory(NotificationCompat.CATEGORY_TRANSPORT); 
    mNotificationManager.notify(NOTIFICATION_ID, builder.build()); 
}

这将强制更新通知栏上的图像。
