Can I override default push notification icon in android from app icon to custom icon?

Question

Can I override default push notification icon in android from app icon to custom icon?

I am using default firebase implementation to display notification in system tray, when a push notification come. Since my app icon is coloured and has gradient, so when a notification comes, android tried to make a black/white version of it, and make it look like a white circle.

Is there a way to update the default notification icon to something else instead of default app icon?

PS: Looking forward for a solution which required a config change in manifest and don't want to use NotificationCompat.Builder

Answer 1

you can use this in your manifest according to https://firebase.google.com/docs/cloud-messaging/android/receive

Click to copy

    <!-- Set custom default icon. This is used when no icon is set for incoming notification
    messages.See README(https://github.com/firebase/quickstart-android/tree/master/messaging#custom-default-icon) for more. -->
    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/ic_stat_ic_notification" />

    <!-- Set color used with incoming notification messages.
    This is used when no color is set for the incoming notification message. See README
    (https://github.com/firebase/quickstart-android/tree/master/messaging#custom-default-color) for more. -->
    <meta-data
        android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/colorAccent" />

Hope it helps people.

A small icon, set by setSmallIcon()
