When I use Handler and its postDelayed method, the run() method executes twice. Below is part of my code.

Handler deneme = new Handler();

deneme.postDelayed(new Runnable() {

            @Override
            public void run()
            {
                randomOyna();
            }
        }, 1000);

where randomOyna is the method

public void randomOyna()
{   
    Log.v("sonOlarak", "çalisti");
}

I monitor the LogCat and see that "çalisti" entry is written twice, so that randomOyna is called twice. The task is scheduled truely, but executes both after 1 sec and 2 secs.

Can you help me???
