I've just tested it after updating all recommended items in the sdk manager. It works fine here.

Are you using B4A v9.50? Have you updated all the recommended resources?

This is the same error as before. Have you updated all recommended resources in B4A Sdk Manager?
Make sure that the IDE is configured to use the correct SDK (path to android.jar).
