bind/java: Do not get ApplicationContext via reflection, ask for it when needed.

Previously any library created using gobind used reflection to get the ApplicationContext. The methods used are disallowed in Android 9 causing any library to crash.  However the ApplictionContext is not required and only needed when using RunOnJvm. This change adds an method to set the ApplicationContext when needed, but will not get it by default by using reflection.

Fixes #31364

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.
