RunTimeException in running timerTask in android

In my android service I am running a simple timer but android throws exception...

My code as follows

public class MyService extends Service{
   private Timer timer = new Timer();

   public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);

      timer.scheduleAtFixedRate(new TimerTask() {

        @Override
        public void run() {
        func1();
        }
        }, 0, UPDATE_INTERVAL);

   }
}


void func1(){
    Log.i(TAG,"Just printing");
}

But my code throws exception like this

09-30 11:56:54.297: ERROR/AndroidRuntime(414): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
