Cant Hide Notification bar in Android 4.3 API 18

Question

Prior to 4.3,

@android:style/Theme.Black.NoTitleBar

and

 requestWindowFeature(Window.FEATURE_NO_TITLE);
 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
 WindowManager.LayoutParams.FLAG_FULLSCREEN);`

works perfectly to hide the Notification bar. But in 4.3 though the bar is not showing using this code but sliding at the top bring the bar

Sliding shows the screen. See that the bar overlapped 134. enter image description here

I found out there is no simple way to do it. So I use bit of reflection and its working fine.

Object service  = getSystemService("statusbar");
Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
Method collapse = statusbarManager.getMethod("collapsePanels");
collapse .setAccessible(true);
collapse .invoke(service);

Don't forget to add this in manifest.

<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />

does this hide the bar only in the current activity? – Behnam Nov 11 '13 at 10:14
I invoked it on touch listeners for every `Activity`. – Mihir Nov 11 '13 at 12:10
Suppose you call another application from your activity, is there any way to hide notification bar in those called applications? – Behnam Nov 11 '13 at 13:42
you can make a background service for that – Mihir Nov 12 '13 at 06:01
OK, I dunno how but that's a good starting point, thanks man. – Behnam Nov 12 '13 at 09:46

Have you tried using Theme.Black.NoTitleBar.Fullscreen?

See images. The notification bar is hidden but gesture at the top of the screen bring it back. – Mihir Aug 23 '13 at 07:29
You said you were using android:style/Theme.Black.NoTitleBar, not android:style/Theme.Black.NoTitleBar.Fullscreen. – gian1200 Aug 23 '13 at 07:55
