I try the examples on https://github.com/golang/go/wiki/Mobile
Native applications -> Building and deploying to Android works fine.
On "SDK applications and generating bindings" I get into problems.
It says:
go get -d golang.org/x/mobile/example/bind/...
I get:
warning: "golang.org/x/mobile/example/bind/..." matched no packages
can't load package: package golang.org/x/mobile/example: no buildable
Go source files in /home/peter/go/src/golang.org/x/mobile/example
But this works:
go get -d github.com/golang/mobile/example/bind/...
But then building in Studio fails.
I edit example/bind/android/hello/build.gradle to set GO and GOPATH, and I
change pkg from "golang.org/x/mobile/example/bind/hello" to
"github.com/golang/mobile/example/bind/hello"
When I do Build -> Make Project, I get:
Executing tasks: [clean, :app:generateDebugSources,
:app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies,
:app:generateDebugAndroidTestSources, :app:compileDebugSources,
:app:compileDebugUnitTestSources, :app:compileDebugAndroidTestSources]
Configuration on demand is an incubating feature.
Incremental java compilation is an incubating feature.
