Answer 1

This solved my problem from https://stackoverflow.com/a/19320065/619673

I added this code for my activity because I was using theme "NO TITLE" for Activity.

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ( keyCode == KeyEvent.KEYCODE_MENU ) {
        // do nothing
        return true;
    }
    return super.onKeyDown(keyCode, event);
}  

Answer 2

public class MainActivity extends ActionBarActivity

Change this to:

public class MainActivity extends Activity
