However, go get golang.org/x/mobile/... prints other errors:

The first set of errors you are seeing are expected, the go tool is enforcing the custom import paths: https://golang.org/s/go14customimport Use go get golang.org/x/mobile instead.

The second GL-related errors are probably because your linux installation is missing the relevant GLES packages. See https://github.com/golang/mobile/blob/master/app/x11.go#L15

Thanks.

@crawshaw I tried second suggestion but still getting same error.

[hyangah]

what command did you run? please use golang.org/x/mobile, not github.com/golang/mobile

@hyangah I was following https://github.com/golang/go/wiki/Mobile tutorial and executed gomobile install golang.org/x/mobile/example/basic. I was able to install apk in my device but when i run it, i only see black screen. Same thing for audio and network example. I was getting "work.h:6:23: fatal error: GLES2/gl2.h: No such file or directory" error when i was executing go install golang.org/x/mobile/example/basic

@ip I tried that option already and it was not working. Now it's working. Thank you.

I am still having problem with mobile. I am only getting black screen. It might be the problem with my device. Thank you @hyangah as well for your time.
