Start context.startService(intent) on Android Pie

Question

I start a service on my activity's onResume, it worked fine on oreo but lately I have been seeing crashes for Android P, which says "Unable to resume Activity.... Not allowed to start service intent ... app is in background..". Has anyone seen this before and where able to apply fix, any input would be much appreciated.

@Override
public void onResume() {
    super.onResume();
    Timber.v("onResume");
    Intent intent = new Intent(context, Token.class);
    intent.setAction(ACTION_FETCH_TOKEN);
    context.startService(intent);
}

just to add more context, I have not been able to reproduce the crash myself.

On Oreo8+ you cannot start a background service if your application is not "shown", to do that you need to edit your code like below:

    protected void onResume() {
        super.onResume(); context.startForegroundService(intent);
 } 

In onCreate() method of your service class you also need to add:

PendingIntent pIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, MainActivity.class), 0);
Notification notification = new NotificationCompat.Builder(this)
                .setContentTitle("My App")
                .setContentText("Doing some work...")
                .setContentIntent(pIntent).build();
startForeground(1000, notification);
