I'm new with FCM. I cannot make FCM use my app icon as notification icon and the icon is always a white blank one.

I imported an icon to mipmap folders but nothing seems changed. As some dude say that this is because of lollipop notification as in this question

But the problem is, the FCM notification automatically pops up and I cannot get the Notification builder to override the icon. How can I change it?

This is the default behaviour of FCM. When app is in background it will take white icon.

Use this tag and put it in your Manifest. For me this worked. Hope it works for you too

<meta-data android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/ic_app_icon" />
