cmd/gomobile,cmd/gobind: allow per-platform bindings again

CL 99316 changed gobind to be platform independent, so
standalone bindings could be generated without having the
Android and Xcode SDKs installed. However, bindings that does
depend on GOOS for its exported API, in particular go source
files that use Cgo now only works if the exported API is
extracted to platform independent files.

By switching to use the source importer, importer.For("source", nil),
gobind can type check the bound packages even in the presence of

The source importer in Go 1.9 and 1.10 has problems with relative
imports and imports from testdata directories (issues 23092 and 24392),
but works from Go 1.10.1 on.

Fixes golang/go#24856

Go support for Mobile devices

The Go mobile repository holds packages and build tools for using Go on mobile platforms.

Package documentation as a starting point:

Caution image

The Go Mobile project is experimental. Use this at your own risk. While we are working hard to improve it, neither Google nor the Go team can provide end-user support.

This is early work and installing the build system requires Go 1.5. Follow the instructions on to install the gomobile command, build the basic and the bind example apps.

Contributions to Go are appreciated. See
