you are using which b4a version? What is the exact error? too many field references?
Or method references? Based on this i would guess you are using an old b4a which is not using the new maven repos...
Or you are adding the jars to your project using #additionaljar?
Help us to help you. Upload a sample project which shows the problem
You can try to add
to your main activity code (if you are using a uptodate b4a)
