Why does my Intent open App Info in Settings for my app, rather than the Activity class I pass to it?

Question

I have an Activity which starts a foreground Service with a Notification. If relevant, the Service may also be set to start on boot, ie. I expect it to be able to start without the Activity also.

I want it to be so that if I tap the Notification, then I go to my Activity where I can stop the service, change settings etc.

I supply an Intent with the Activity class to a PendingIntent for a Notification for the foreground Service.

If I tap the Notification it opens the App Info in system settings for my app (where you can Force Stop, Uninstall etc.), not the Activity itself. How can I make it do the latter?

This is the code that creates the Notification when the service starts:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Context con = getApplicationContext();
    String chanID = "com.blah.MyApp";
    NotificationChannel chan = new NotificationChannel(chanID, getString(R.string.app_name), NotificationManager.IMPORTANCE_NONE);
    NotificationManager manager = (NotificationManager) con.getSystemService(Context.NOTIFICATION_SERVICE);
    manager.createNotificationChannel(chan);

    PendingIntent penitent = PendingIntent.getActivity(con, 1, new Intent(getBaseContext(), MyApp.class), 0);
    Notification notif = new NotificationCompat.Builder(con, chanID).setContentIntent(penitent).build();

    startForeground(1, notif);
...

I have also tried creating the Intent with

 Intent.makeMainActivity(new ComponentName("com.blah", "MyApp"));

with the same result. I wonder if the problem has to do with Contexts?

EDIT: I could not change the text on the notification either.

I should also mention this is the LineageOS Android flavor. Thank you.

Answer 1

This works if I set an icon, which I hadn't made yet, due to artistic deficiencies. Unlike this question it is not necessary to set the icon first in this case.

It is as if it ignores the notification passed to the startForeground method and supplies a default one unless it includes an icon.

Once I added that via setSmallIcon(R.drawable...) all worked as expected.
