Go 1.4 can build binaries for ARM processors running the Android operating system. It can also build a .so library that can be loaded by an Android application using the supporting packages in the mobile[1] subrepository. A brief description of the plans for this experimental port are available here[2].
At this stage, the support libraries are still nascent and under heavy development. *** Early adopters should expect a bumpy ride ***, but we welcome the community to get involved.
