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

Look at the documentation: http://developer.android.com/design/style/iconography.html

there are words: "Notification icons must be entirely white. Also, the system may scale down and/or darken the icons."
