Android App崩溃原因

Question

I am new with eclipse I don't know how to find the why app is crashing at start. I am compiling cocos2d-x app that I used first build_native.sh file to compile, then I used Eclipse for testing on device when I tested it says unfortunately your app crashed

Here is the log:

It seems that the problem is that the compiler cannot find your so libraries. Is this your project or you just downloaded it from the Internet? If it is from the Internet then you should also check if this project uses native code (does it have smth like jni folder with .c, .cpp or .h files?). If yes, then you should at first build your native part and only after this you can make a build of your code.
