NotificationCompat.Builder setLargeIcon() not working?

Question

When I add the code mNotificationBuilder.setLargeIcon(BitmapFactory.decodeResource( getResources(), R.drawable.ic_large_icon)); to my notification it stops working without errors or warnings. This only happens on pre-Lollipop, on Lollipop and beyond it works great. And with "works" I mean that the notification shows up.

My sample code:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);

mBuilder.setSmallIcon(R.drawable.icon);
mBuilder.setContentTitle("Content Title");
mBuilder.setContentText("Content Text");
mBuilder.setLargeIcon(BitmapFactory.decodeResource( getResources(), R.drawable.ic_large_icon));

startForeground(1, mBuilder.build());

I have tried to load the Bitmap in different ways but it keeps failing... The icon is 128x128 so the size of it should not be a problem?

I have also tried different id's but none that solves the problem.

I would be so greatful of any advice, please any push in the right direction would mean the world to me.

EDIT 1#

This notification is issued from a Service. The service is alive and Log prints tell me that code after "startForeground()" is run.

You have to first set large icon then small icon.

in my case this code is working:

    mBuilder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_message));
    mBuilder.setSmallIcon(R.mipmap.ic_message);
    mBuilder.setContentTitle("Inbox");
    mBuilder.setContentText("New message received");
