Do you get the same error when compiling for Windows desktop?

The error shown there looks to be a Java error. The error seems to stem from two different versions of the same library being linked into building when compiling for Android. I don't do Java, but I vaguely recall that there is a way to force the Java compiler to choose a particular version of a library.

They are firebase libraries. I deleted one of the folders and it solved the problem.
