The problem is with firebase-datatransport v18.0.0.

Be careful with installing resources not in the recommended items list.
Edit <android sdk>\extras\b4a_remote\installed-components.txt

Set the version to the previous one. On my SDK it is 17.0.11.

You can find it here: <sdk>\extras\b4a_remote\com\google\firebase\firebase-datatransport

Clean the project (Ctrl + P) and compile.
