Context.startForegroundService() did not then call Service.startForeground

Question

My app will call startForegroundService(intent) in the onCreate of the MainActivity. And I put startForeground(ON_SERVICE_CONNEC

Answer 1

i had the same problem.
What helped me in the end, was to initialize the NotificationChannel as early as possible ( i did it in the application class itself) and then create and use the notification in the service.

I put this in the Application class:

private void createNotificationChannel() {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        CharSequence name = "MyStreamingApplication";
        String description = "radio";
        int importance = NotificationManager.IMPORTANCE_DEFAULT;
        NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, name, importance);
        mChannel.setSound(null, null);
        mChannel.enableVibration(false);
        mChannel.setDescription(description);
        notificationManager.createNotificationChannel(mChannel);
    }
}

and in the onStartCommand method of the service i call:

if (Build.VERSION.SDK_INT > Build.VERSION_CODES.N_MR1) {
        startForeground(NOTIFICATION_ID, createNotification());
    }
