- Now they are in ndkHelper:: name space - Changed module name to ndk_helper - Changed some static members to class var or stand alone function - Added syncronization for JNIHelper.cpp - For a documentation, I will work with doc writer for future improvement Change-Id: I0055061a4f53b1904cde2e0339550ee277b35fc5 Addressed most of feedbacks, - Switched coding standard to Chrome style - Update JNI helper, and documented - Fixed other issues that is pointed out Change-Id: Icc729a55ed8dd613759f34a3fc35cb4949d2d205
