Hello there! Just got an error on appcompat, don't know what this exactly. I've already tried to remove the lines specified but then many errors appears after removing those line. Anybody please explain to me further. Sorry for my bad english.

1. Delete all appcompat.* files from additional library folder
2. Use the newest b4a version. Appcompat is a internal library in 9.9.
3. If 1+2 does not work then suggest to reinstall the SDK
