If I generate the Notification from Firebase notification icon is not coming.(App is in background). Icon is coming if App is in foreground.
I came to know that after lot of research.
If App is in background it won't call OnmessageReceivedmethod();
So for that we have to override OnHandleIntent()
method but I am unable to override it .Why because it is final..
Please give me some solution for this??

please use this icon for notification icon 1
If you have difficulty in setting the icon size use android studio's image asset maker in android studio 3.0.1 which also allows to generate notification icon.
Also try to make your icon single color.
Also set the default icon for firebase notification:
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/ic_notification_default" />
