Replace native outgoing call Screen by custom screen android -

i trying launch custom screen on top of native outgoing caller screen may contain full screen image of caller , buttons actions reject call. using able make call, redirecting me native caller screen...

how replace\override default call screen custom screen screen?

startactivity(new intent(intent.action_call, uri.parse("tel:" + phonenumber))); public class getoutgoingnumber extends broadcastreceiver {   final static string intent_phone_number = "android.intent.extra.phone_number";  @override public void onreceive(context context, intent intent) {     // todo auto-generated method stub     log.v("dilebroadcastreceiver","in onreceive()");      if (intent.getaction().equals(intent.action_new_outgoing_call)) {           new handler().postdelayed(new runnable() {              @override              public void run() {                  intent = new intent(context, outgoingscreen.class);                 i.putextras(intent);                 i.addflags(intent.flag_activity_new_task);                 i.addflags(intent.flag_activity_single_top);                 context.startactivity(i);              }          }, 1000); } 

here outgoingscreen displaying outgoing screen

  public class outgoingscreen extends activity {  @override     protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);      setcontentview(r.layout.outgoingscreen );      } } 

now problem is showing screen few msec , again showing native screen....?

write receiver outgoing call

public class outgoingcallreceiver extends broadcastreceiver { @override     public void onreceive(final context context, final intent intent) {       //write intent yout page   } } 

add these manifest

<uses-permission android:name="android.permission.process_outgoing_calls" /> <uses-permission android:name="android.permission.read_phone_state" />  <receiver android:name=.outgoingcallreceiver" >    <intent-filter>       <action android:name="android.intent.action.new_outgoing_call" />    </intent-filter>  </receiver> 

add below theme activity theme

android:theme="@android:style/theme.translucent.notitlebar.fullscreen" 

open intent after 1 second bcoz original outgoing call screen takes 800ms open need on lay screen, must call intent after 800ms. works me.
