"more complete support for Android" Will we be able to write at least a simple CRUD android app using pure Go?

Per http://golang.org/s/go14android http://golang.org/s/go14android, apps that don't need the Android UI (e.g. if it's only using OpenGL) should not need Java and could be written in pure Go.

  In fact, there's a user on Reddit that built an entire Android app with a UI using a webview: https://github.com/MarinX/godroid https://github.com/MarinX/godroid and http://www.reddit.com/r/golang/comments/2kv0s1/go_14_on_android/clpuscd http://www.reddit.com/r/golang/comments/2kv0s1/go_14_on_andr... It's entirely possible right now — we just need it to mature.

    Webview != pure Go, which is what the OP was asking for.

      My point was that even apps that do need a UI can be written without Java using Go.

        Faire enough.

No, if you want to use Android UI. The NDK doesn't offer support for the Android APIs besides graphics, sensors and audio. POSIX is also only partially available. So you will need to either use JNI or write your own UI with OpenGL.

Go Android support won't magically rewrite Android Java APIs (which is most of them, including whole UI toolkit).

  even if Android is running on ART binary rather than Dalvik ? I have been debating whether you can write code in Go that will work in the JVM GC and is linked through ART... not sure if it is possible.

    Go semantics are too different from Java. So unless the Android team implements something like Windows Phone language projections (APIs metadata), it won't happen.
