Why do icons set with Notification.Builder.setSmallIcon in Android Lollipop show as a white square?

Question

I have this code:

Notification notif;

// Build notification
Notification.Builder notifBuilder = new Notification.Builder(context);
notifBuilder.setContentIn         


        

Answer 1

In Android 5.0 the icon showed in the status bar is a white square because of 5.0 Lollipop "Notification icons must be entirely white".

You can easily find this types of icons on the Material icon. Visit: https://material.io/icons/

Google also suggests that we use a custom color that will be displayed behind the white notification icon using setColor() method.
