set/unset fullscreen mode
<p>Using this code I can start my app in "full-screen mode". I ask what's the best way to toggle it (ie touch the screen)</p>

<pre><code>requestWindowFeature(Window.FEATURE_NO_TITLE); 
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                       WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_act);
</code></pre>

<p>thanks!</p>
