Android.app.RemoteServiceException: Bad Notification For StartForeground

I'm trying to start foreground service as follow: if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { NotificationChannel chan = new NotificationChannel( g

Solution 1:

Issue is happening because you are creating a channel with an ID but sending the notification in a different ID:

// Here, you are using the package name as channel ID
NotificationChannel chan = new NotificationChannel(
              getApplicationContext().getPackageName(), 
              "My Foreground Service",
              NotificationManager.IMPORTANCE_LOW);

// But here, you are sending notifications to "MyChannelId"
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder( 
              this, "MyChannelId");

So, I believe you just need to change Channel ID to MyChannelID as follows:

NotificationChannel chan = new NotificationChannel(
              "MyChannelId",
              "My Foreground Service",
              NotificationManager.IMPORTANCE_LOW);
