I would like to add a menu button in the System bar of Android 3.0, attached is a picture of the Firefox app on Android 3.0 which gives the system bar menu button and on clicking the button you see 4 options(Site Options, Preferences, Add-ons, Downloads). I would like to know how do I add this button(marked in red) in the system bar and also its corresponding options.

P.S: I have already tried adding the methods nCreateOptionsMenu(Menu menu) and onOptionsItemSelected(MenuItem item), but these methods give me menu button in the action bar, which I dont’ want.
Thanks
That is because Firefox is not updated for Honeycomb. Once it is, their options menu will be in the action bar. Over time, all applications’ options menus will be in the action bar. Options menus in the system bar are only for pre-Honeycomb apps.
