Resolved Unable to load plugin `HavokNative` on Android platform

The build version of the project can be able to load Havok Physics successfully on Windows standalone platform. Sadly, it can not be able to load 'HavokNative' plugin on Android platform.
Then I have tried to build the physics samples project on Android platform, but it still reports the same error.

Hi @JosepMariaPujol, fortunately I have figured out the reason why havok plugin cannot be loaded on android platform. The file name of the android native library is required to start with 'lib'. Therefore, just rename 'havoknative.so' to 'libhavoknative.so' and the problem will be solved. Hope that this bug will be fixed soon.
