Integrating Box2D in an Android project

cocos2d-x C++
#61

I have actually followed the tutorial completely and finally compiled it. I have also added the following lines:
static {
System.loadLibrary(“game”);
System.loadLibrary(“box2d”);
System.loadLibrary(“cocos2d”);
System.loadLibrary(“cocosdenshion”);
}

Still the application is crashing at start. Can someone help me out. I am printing the stacktrace below.
