I have achieved this in my project using below code First of all, add permission in AnroidManifest.xml:

<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" />

Now set full screen intent in your notification builder with your activity as below:

var answerCallIntent = Intent(this@FirebaseInstanceService, AnswerDeclineCallActivity::class.java)
var answerCallPendingIntent = PendingIntent.getActivity(this@FirebaseInstanceService,
   0, answerCallIntent, PendingIntent.FLAG_UPDATE_CURRENT)
   setFullScreenIntent(answerCallPendingIntent, true)

Note : Some devices like Xiaomi, you have to redirect user to settings to enable "show on lock screen" permission to show activity in lockscreen.

Make sure you have set priority to max in notification builder:

.setPriority(Notification.PRIORITY_MAX) //Important for heads-up notification
