Leere Benachrichtigung auf einem Android-Gerät erhalten

Question

In einigen Geräten erhalte ich eine leere (weiße) Benachrichtigung wie angehängter Screenshot. Und in einigen Geräten funktioniert es gut. Bitte helfen Sie mir, dieses Problem zu lösen.

Intent intent = new Intent(ctx, NotificationDetailActivity.class); 
      intent.putExtra("id", id); 
      PendingIntent pendingIntent = PendingIntent.getActivity(ctx, 0, intent, 
        PendingIntent.FLAG_ONE_SHOT); 
      Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
      NotificationCompat.Builder builder = new NotificationCompat.Builder(ctx); 
      builder.setTicker(getResources().getString(R.string.app_name)); 
      // Sets the small icon for the ticker 
      builder.setSmallIcon(getNotificationIcon()); 
      builder.setLargeIcon(result); 
      builder.setColor(getResources().getColor(R.color.colorPrimary)); 
      builder.setContentTitle(title); 
      builder.setContentText(messageBody); 
      builder.setSound(defaultSoundUri); 
      builder.setContentIntent(pendingIntent); 
      builder.setAutoCancel(true); 
      Notification notification = builder.build(); 
      RemoteViews expandedView = 
        new RemoteViews(ctx.getPackageName(), R.layout.custom_notification); 
      if (Build.VERSION.SDK_INT >= 16) 
      { 
       // Inflate and set the layout for the expanded notification view 
       expandedView.setImageViewBitmap(R.id.imgBigImage, result); 
       notification.bigContentView = expandedView; 
       NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
       nm.notify(Integer.parseInt(id), notification); 
      } else { 
       NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(ctx) 
         .setSmallIcon(getNotificationIcon()) 
         .setLargeIcon(result) 
         .setColor(getResources().getColor(R.color.colorPrimary)) 
         .setContentTitle(title) 
         .setContentText(messageBody) 
         .setAutoCancel(true) 
         .setSound(defaultSoundUri) 
         .setContentIntent(pendingIntent); 
       NotificationManager notificationManager = 
         (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
       notificationManager.notify(Integer.parseInt(id), notificationBuilder.build()); 
      }

auf diese Weise zu setBigContentView-NotificationCompat.Builder Versuchen Sie, ob es funktioniert: -

Intent intent = new Intent(ctx, NotificationDetailActivity.class); 
    intent.putExtra("id", id); 
    PendingIntent pendingIntent = PendingIntent.getActivity(ctx, 0, intent, 
      PendingIntent.FLAG_ONE_SHOT); 
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
    NotificationCompat.Builder builder = new NotificationCompat.Builder(ctx); 
    NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
//  Notification notification = builder.build(); 
     RemoteViews expandedView = 
       new RemoteViews(ctx.getPackageName(), R.layout.custom_notification); 
     if (Build.VERSION.SDK_INT >= 16) 
     { 
      builder.setTicker(getResources().getString(R.string.app_name)); 
      // Sets the small icon for the ticker 
      builder.setSmallIcon(getNotificationIcon()); 
      builder.setLargeIcon(result); 
      builder.setColor(getResources().getColor(R.color.colorPrimary)); 
      builder.setContentTitle(title); 
      builder.setContentText(messageBody); 
      builder.setSound(defaultSoundUri); 
      builder.setContentIntent(pendingIntent); 
      builder.setAutoCancel(true); 
      // Inflate and set the layout for the expanded notification view 
      expandedView.setImageViewBitmap(R.id.imgBigImage, result); 
//   notification.bigContentView = expandedView; 
      builder.setCustomBigContentView(expandedView); 
     } else { 
      builder.setSmallIcon(getNotificationIcon()); 
      builder.setLargeIcon(result); 
      builder.setColor(getResources().getColor(R.color.colorPrimary)); 
      builder.setContentTitle(title); 
      builder.setContentText(messageBody); 
      builder.setAutoCancel(true); 
      builder.setSound(defaultSoundUri); 
      builder.setContentIntent(pendingIntent); 
     } 
     nm.notify(Integer.parseInt(id), builder.build());
