x/mobile: Cannot use two different libraries built with gomobile in the same Android app

What version of Go are you using (go version)?

$ go version
go version go1.13.1 linux/amd64

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

go env Output

What did you do?

I am trying to build an Android app that uses keybaselib and libuplink as dependencies. These two Android libraries are both built with gomobile.

What did you expect to see?

I expected that building my Android app with these two dependencies would be successful.

What did you see instead?

Building the app failed with this error:

More than one file was found with OS independent path 'lib/x86/libgojni.so'

Both libraries are built with gomobile, so both have libgojni.so in their AARs. So they conflict when added as dependencies in the same Android app.

Are there any guidelines how to use more than one Android library built with gomobile in the same Android app?
