Hi,

If you set targetSdkVersion >= 21 on Android Lollipop and higher devices, the system will use only an alpha-channel of your icon. See more in Android documentation:

https://developer.android.com/about/versions/android-5.0-changes.html#BehaviorNotifications

The system ignores all non-alpha channels in action icons and in the main notification icon. Assume these icons will be alpha-only. The system draws notification icons in white and action icons in dark gray.

Therefore, you should create a notification icon according to material design guidelines:

https://material.io/guidelines/style/icons.html#notification

You can use the following tool to generate and preview a notification icon:

@mobileias could you please specify what exactly is not working fine? How does your icon appear on Android 6.0 devices? Did you try it with other Android versions (Lollipop, Nougat)? Also, could you please share a link to your new icon that was created according to this guide?

"The system ignores all non-alpha channels in action icons and in the main notification icon." What does this actually mean? Are colour notification icons supported, or are they always shown in gray & white?

@mobileias

If you set a default notification icon it should appear in the same manner on all Android devices.

Could you please specify which particular device is still showing the icon incorrectly? Also, could you please share your icon so we could test it on our side?

Android icon on Android 5+ consists of two parts: a big custom icon and a small default notification icon. The latter will always appear gray&white. If you do not set a large icon, the small one will be used instead. Action icon in status bar also appears white.

You can set a large icon remotely by adding "android_custom_icon":"URL_path_to_your_icon" to a push payload. Small icon is a default notification icon, however can also be set with "android_icon" key in payload. "android_icon" can only use icons from your application bundle.
