public void triggerReadyToSend() {
  // TODO Auto-generated method stub
  Log.i(TAG,"Succese Connected and Actived RdpCanvas");
  Intent intent = new Intent(rdpCanvas, RdpCanvas.class);
  startActivity(intent);
//  RemoteCanvas remoteCanvas = new RemoteCanvas(this);
//  remoteCanvas.triggerReadyToSend();
    
 }

 rdp 클래스에서 readtoSend가 true값을 가지면, 
 main클래스의 triggerReadyToSend() 메소드를 호출하여
rdpCanvas 클래스를 호출하고 싶습니다.
