Override isShown() method in your SlideMenu Class

[ravikumar-n]

Since slidemenu.isShown() method returns "true" even though menu was not shown. The below code(What I thought to be valid) ends up in exception since menu object is null.

public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_MENU) {
if(slideMenu.isShown())
slideMenu.hide();
}
}
