I am setting a specific activity full screen when the use hits a START button.

In this case the showStopButton() is called .

It\'s running fine

Answer 1

it's so simple ... I just need to hide the ActionBar... then show it when back to standard screen...

   private void showStopButton(){
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
        ActionBar actionBar = getActionBar();
        actionBar.hide();
        getWindow().findViewById(android.R.id.content).requestLayout();
