Android：Firebase 应用程序在前台时推送通知不同的图标，而当应用程序在后台时，另一个图标

Question

How can I show same icon while app is on background or foreground? Below I have attached my screenshot

I have used this app icon for my notification

Thanks in advance!

Yes. This does happen. It can be fixed by setting color to the icon,when the notification is generated from inside the app.

 NotificationCompat.Builder(
 this,
 CHANNEL_ID
 )
.setSmallIcon(//your vector)
.setColor(ContextCompat.getColor(this, //color of the icon(mostly this may be 
the primary/secondary color that has been set ,according to the theme, in this 
case some hex of red)))

To keep it consistent, even for the notification generated in the background, a line can be written in the manifest:

<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/(your vector)” />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="@color/(color of the icon)” />
