Im using parse to send push notifications, The problem is that when I send push notifications the top bar in the emulator shows only a white square and not the icon, when I get the notification on the real device, samsung s6, samsung nexus, this is working great(I have tested only on this two devices).
any ideas?
Due to the new design changes introduced in Android 5.0, you need to use to the notifications only white icons. You can read more about it here: https://developer.android.com/design/patterns/notifications.html#guidelines
The system will automatically convert your icons to white. My suggestion is to you create white notification icons.
