I have the same problem. After upgrading from v345 to v350, the Android client no longer works. It displays the group tabs, but no modules appear and i just get a black screen.
I can change the groups but all of them are empty (no modules displayed).
Home genie web interface still works, but i did have to do a restore to get it to work after the upgrade - before this all module were shown as generic and diddnt work.
