title: Android incoming call interception , call forwarding
body: <p>I would like to know how to intercept incoming calls and also how to forward them. I know there are several questions regarding this topic here and elsewhere on the net, but all the answers use the android.intent.action.PHONE_STATE action which is broadcast always after the phone begins to ring and the call screen is shown.<br>
  That's why I'm looking for a solution where i could intercept the call in an early stage before any notification (ringing etc..) has been done. I would like to know if maybe this is possible on a platform level in native code and if yes how ? Or perhaps with some kind of trick with the SDK ?</p>
