Notification icon on status bar is coming as white box

Question

How do i customize the notification icon on the status bar in my phone running Android 5.0. It always comes as a white box(image attached).

The notification icon in the notification bar comes colorful as expected but the status bar icon comes as white square box. l

Answer 1

android 5.0 uses the icon that you give him and puts a color filter on it. If you want to see your icon, you must use an icon with transparency (png). I advice you to set another icon other than the icon of your application and remove the rectangle with rounded border.

Answer 2

There is some restrictions for notification icons. And also Lollipop doesn't show exactly what you set. It flatifies the notification icons and also suggest you to use flat style icons.
