Question

I’m trying to launch a non cancellable ongoing notification but no matter what I try it is cancellable.

code:

    NotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    int icon = R.drawable.btn_rating_star_on_pressed_holo_light;
    long when = System.currentTimeMillis();

    notification = new Notification(icon, getString(R.string.notificationMSG), when);
    notification.ledARGB = 999;

    Intent notificationIntent = new Intent(this, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, Notification.FLAG_ONGOING_EVENT + Notification.FLAG_NO_CLEAR + Notification.FLAG_SHOW_LIGHTS);

    notification.setLatestEventInfo(context, getString(R.string.app_name), getString(R.string.notificationMSG), contentIntent);

    notificationManager.notify(Global.NOTIFICATION_ID,notification);

I would also like to know how to make it go away once the activity that launched it is finished. Tried doing the following but it works only some times.

@Override
protected void onDestroy(){
    notificationManager.cancel(Global.NOTIFICATION_ID);
    super.onDestroy();
}

Answer 1

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

notification.flags |= Notification.FLAG_ONGOING_EVENT;
notification.flags |= Notification.FLAG_NO_CLEAR;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;

For some stupid reason we cannot put the flags directly in the PendingIntent and need to set them this way instead.
