How to know which app is opening when an incoming call come?

I'm using a broadcast receiver to get notified when there is an incoming call. Now I need to know if a specific app, say Facebook, is opening when the call happens to do my work.

Is this possible?


I've tried Hamid Shatu's answer but it always returns
because this app always tops on other applications.

Answer Source

After receiving BroadcastReceiver, check the current on-screen activity which is other than Home screen.

To check on-screen activity, get the top activity using ActivityManagerby getting running task list.

For example:

ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(2);
ComponentName componentInfo = taskInfo.get(1).topActivity;
String callHandlerPackageName = componentInfo.getPackageName();

Log.d("Call_incoming", "Call_receiver_app ::" + callHandlerPackageName);

You will need the following permission on your manifest:

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

Note: the above functionality is deprecated in Marshmallow version. I just giving you here an example by code snippet.
