I am working with the latest gomobile, Go, and Android Studio builds.

When I run the gradle tasks from the terminal they work as expected and build the correct binaries, however from within Android Studio I receive an error:

bin/gomobile: toolchain out of date, run `gomobile init`

Of course I have re run gomobile init many times and no change. My assumption is that Android Studio is using some config that I can not identify.

I appreciate this is a somewhat edge case question, but if anyone can point me in the right direction it would be helpful.

TLDR; ./gradlew myproj:bind works fine in terminal, fails in Android Studio.

如果其他人有问题，我已经深入了解了；

  1. 看来，至少对我来说，Gradle 插件不尊重 GO bin 的位置。相反，它使用以下方式查找 gobin；

            gobin, err := exec.LookPath("go")

我安装了许多 Go 版本（出于各种原因），所以我强制 gobin 失败了。为了发现这一点，我在env.go文件中添加了调试日志。通常，在尝试调试时，文件上的日志记录并不是最清楚的。

这似乎是一条 gomobile 错误消息，见于cmd/gomobile/env.go#L69-L83：

// Find gomobilepath.
gopath := goEnv("GOPATH")
for _, p := range filepath.SplitList(gopath) {
    gomobilepath = filepath.Join(p, "pkg", "gomobile")
    if _, err := os.Stat(gomobilepath); buildN || err == nil {
        break
    }
}

verpath := filepath.Join(gomobilepath, "version")
installedVersion, err := ioutil.ReadFile(verpath)
if !bytes.Equal(installedVersion, version) {
    return nil, errors.New("toolchain out of date, run `gomobile init`")
}

因此，请仔细检查GOPATH本地会话和 Android Studio 会话之间的值。
例如，请参阅这个旧的（2015 年）线程，看看这些评论是否仍然适用。
