client Ibinder 인터페이스 대상을 어떻게 호출합니까

	public void funclick(View view){
		Intent _intent = new Intent(MainActivity.this,MyService.class);
		bindService(_intent, conn, BIND_AUTO_CREATE);
	}
	
	private ServiceConnection conn = new ServiceConnection() {

		public void onServiceConnected(ComponentName name, IBinder service) {
			String mynameStr = ((MyBinder)service).helloWorld("bitch");
			Log.e("mynameStr", mynameStr+"~");
		}
	};
