app: support importing the package for bind programs

Delay loading of the getRune method ID to the first GoNativeActivity
is created. That way, importing golang.org/x/mobile/app will not
crash, even for gomobile bind programs that don't include (or use)
GoNativeActivity.

Fixes golang/go#24490

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 golang.org/wiki/Mobile to install the gomobile command, build the basic and the bind example apps.


Contributions to Go are appreciated. See https://golang.org/doc/contribute.html.
