this doesn't needs to be a member function?

[Changwan Ryu, 2014/09/22 14:02:38]

Hmm.. This is accessed by Java. Is there any way I can get a static non-member
function accessed by Java? Please let me know.

In java side, if you declare you native call without the native pointer, it will
call the static function inside this class.
For example, you can have
nativeGetUniqueFilepath(String path) in java.
And then declare static ScopedJavaLocalRef<jstring> GetUniqueFilePath(JNIEnv*
env, jclass, jstring) in the cc file.
