Error building Player: CommandInvokationFailure: Failed to re-package resources

I have a problem when I try to build an apk from my project(I can build it for ios and there is no problem about it). I think it's about nextpeer library or about the android manifest, I really need your help, please. Here is the error log it shows in the console after the build fails:
