Is there any way to make the System bar be hide permanently?
<p>I have a problem on making the System bar (or Navigation bar) on Android device: Is there any way to make the System bar be hide permanently?</p>

<p>The function setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION) will hide the System bar (or Navigation bar). But when user touch on the screen the System bar will re-appear immediately. </p>

<p>There are some threads that confirmed "the System bar will re-appear when user touch on screen" (due to the design). There are also some applications on market that can make the System bar be hide permanent. 
Thus, I believe there is a way or an algorithm that will make the System bar hide without any reaction by the user's touch. 
I post this thread that hope there are some one that can help me.</p>

<p>Thanks in advance!</p>
