Many Thanks DonManfred for your support.
But is not very easy for me to follow instructions in english. B4Xdrawer is very easy to install it in B4i and is very hard to install in B4A.

Than I thing it is more easy for me to add a panel "menu" (show/hide) by my self.

Hi JimmyF, It's hard for me. Many and complex instructions. So I make my menu with panel and xcustomlistview. That's very simple for me.

B4XDrawer has nothing to do with AppCompat. The example combined both features.

Than why put a small project with AppCompat?

It happens in his app, not in the b4x drawer example. And in his app he did not successfully added the appcompat compatibility.
