I tried laz4android + CustomDrawn, but fails on my Android 5 phone. Now I'm learning Android Module Wizard (LAMW) which is so far seems no problem with Android 5. LAMW is harder to learn especially for beginners. But it comes with lots of demos and has many features that are great, like configuring app permissions, form behaviors, OpenGL ES support, accessing web and camera, etc.
While waiting experts to fix CustomDrawn/laz4android with the Android 5 issue, you may try learning LAMW. Believe me, you won't regret.
