With Go 1.7.1 and after removing my existing $GOPATH/golang.org directory out of the way, running
$ go get -d golang.org/x/mobile/example/bind/. <http://golang.org/x/mobile/example/bind/>.. outputs no error and downloads golang.org/x/mobile just fine. Which version of Go are you using? Regardless of this issue, I recommend 1.7.1 because it contains fixes for several issues on mobiles, in particular iOS. > 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. > :app:clean > :hello:clean UP-TO-DATE > :app:preBuild UP-TO-DATE > :app:preDebugBuild UP-TO-DATE > :app:checkDebugManifest > :app:preReleaseBuild UP-TO-DATE > :hello:gobind > :app:prepareAndroidHelloUnspecifiedLibrary > :app:prepareComAndroidSupportAppcompatV72211Library > :app:prepareComAndroidSupportSupportV42211Library > :app:prepareDebugDependencies > :app:compileDebugAidl > :app:compileDebugRenderscript > :app:generateDebugBuildConfig > :app:generateDebugResValues > :app:generateDebugResources > :app:mergeDebugResources > :app:processDebugManifest > :app:processDebugResources > :app:generateDebugSources > :app:mockableAndroidJar UP-TO-DATE > :app:preDebugUnitTestBuild UP-TO-DATE > :app:prepareDebugUnitTestDependencies > :app:preDebugAndroidTestBuild UP-TO-DATE > :app:prepareDebugAndroidTestDependencies > :app:compileDebugAndroidTestAidl > :app:processDebugAndroidTestManifest > :app:compileDebugAndroidTestRenderscript > :app:generateDebugAndroidTestBuildConfig > :app:generateDebugAndroidTestResValues > :app:generateDebugAndroidTestResources > :app:mergeDebugAndroidTestResources > :app:processDebugAndroidTestResources > :app:generateDebugAndroidTestSources > :app:incrementalDebugJavaCompilationSafeguard > :app:compileDebugJavaWithJavac > :app:compileDebugJavaWithJavac - is not incremental (e.g. outputs have > changed, no previous execution, etc.). > > /home/peter/go/src/ > github.com/golang/mobile/example/bind/android/app/src/main/java/org/golang/example/bind/MainActivity.java:27: > > error: cannot find symbol > String greetings = Hello.Greetings("Android and Gopher"); > ^ > symbol: method Greetings(String) > location: class Hello > 1 error > > :app:compileDebugJavaWithJavac FAILED > > > > Java methods names were recently changed to lowercase, but the examples weren't updated. That's unfortunate, but thank you for reporting. FWIW, I've mailed https://go-review.googlesource.com/c/29594/ to fix the two examples and to comment out the GO, GOMOBILE and GOPATH settings from the build.gradle file. They're more confusing than helpful. - elias -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
