Android’s UI components are not thread safe so one may need to update Views or other UI components from a secondary thread when returning from an asynchronous database query or a web service call. If you run the code from a secondary thread you might see that the code crashes almost on each try.

runOnUIThread Activity’s method

yourActivity.runOnUiThread(new Runnable(){
     public void run() {
          // UI code goes here
     }
});

I hope that it helps you.
