Put the functions in an anonymous namespace instead of using "static".

[Bernhard Bauer, 2016/02/10 10:48:44]

You don't need Init() or Destroy() anymore either -- just make this class purely
static.

That does not work for JNI bridge methods (because they are declared in the
generated header, but we still want them to get internal linkage).

Today I learned! Alright, carry on then :)

Done.
