Have you rebuilt the gomobile commands? (go install golang.org/x/mobile/cmd/...) I get

gomobile: package "github.com/hajimehoshi/gomobilebindtest": no buildable Go source files in /home/elias/dev/go/src/github.com/hajimehoshi/gomobilebindtest

Which is caused by CL 99777 that again adds GOOS=android to gomobile bind -target=android builds.

[hajimehoshi]

Yeah I did go install so that I'm using the latest gomobile binaries.

Change https://golang.org/cl/108336 mentions this issue: cmd/gomobile: add CGO_ENABLED=1 to gobind runs

[eliasnaur]

Can you test CL 108336?

[hajimehoshi]

Yeah that worked. Thanks!
