Object service = getSystemService ("statusbar");
        try {
Class <?> statusBarManager = Class.forName
("android.app.StatusBarManager");
Method expand = statusBarManager.getMethod ("disable",int.class);
expand.invoke (service,0x00000001);
} catch (Exception e) {
e.printStackTrace();
}

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