Detect if an outgoing call has been answered

Once ACTION_NEW_OUTGOING_CALL has been broadcasted, I need to capture the following event of the other party answer. Could you advice on how to achieve that please? I know it is possible as the Android dialer app changes the green Android icon to the person's photo exactly when they pick up.

UPDATED: I've had a look at the source of the app on Android handling the outgoing calls. I noticed the following method in ContactsUtils:

/**
 * Kick off an intent to initiate a call.
 */

 public static void initiateCall(Context context, CharSequence
 phoneNumber) {
     Intent intent = new Intent(Intent.ACTION_CALL_PRIVILEGED,
             Uri.fromParts("tel", phoneNumber.toString(), null));
     context.startActivity(intent); }

I guess my answer is in the activity listening for Intent.ACTION_CALL_PRIVILEGED. So to rephrase my question: Does anyone know which activity handles Intent.ACTION_CALL_PRIVILEGED?

It does not necessarily needs to be possible to capture this as an outside app. The green android icon is a part of the application that controls the call, so it does not need a broadcast to change the icon.

The only way you may be able to do this is by parsing the Logcat logs, no PhoneStateListener event is available for that.

Some are asking for it here: https://code.google.com/p/android/issues/detail?id=14266

Anyway, in versions above Android 4.2 as Logcat is "sandboxed" it may be impossible...
