Did you upgraded from a B4A version prior to 12.50?
In this case you need to even download the new SDK.
Follow exactly and carefully all the steps here, like a first install:

Might be an old jar file in the internal libraries folder. Best to manually delete the internal libraries folder and reinstall B4A.
