I believe you are doing this in Oncreate or onResume. You will only need to call this api after the operation window has been initialized. One way is to post the delayed runnable in your onresume to the ui thread.

thanks for ur replica ..... i found a solution from mr.Nandeesh post. I just added the following code and its work ...

 public void onResume()
{
    new Handler().postDelayed(new Runnable() { 
       public void run() { 
           openOptionsMenu(); 
       } 
    }, 500); 

    super.onResume();
}
