Cocos2dx如何引用第三方SO文件(Android NDK)

做项目的过程中发现，引用第三方的库lib3rdsdk.so，当直接把lib3rdsdk.so放进armeabi文件夹里，会被删除掉。查网上资料都说的不全，经过实验，最简单的方法就是在jni下的android.mk里加下面3-7行就可以，要放最前面，放后面有可能不行哦，因为编译路径有可能会被改掉。

其中prebuilt/$(TARGET_ARCH_ABI)中的prebuilt就是jni里新建的prebuilt文件，其实建不建无所谓，prebuilt里面有4个文件夹：armeabi、armeabi-v7a、mips、x86，每个文件夹里放着不同架构的lib3rdsdk.so库， $(TARGET_ARCH_ABI)则是按cpu架构自动选择armeabi、armeabi-v7a、mips、x86这些架构中的库，默认只会复制armeabi中的libtxpay.so库，比如需要多复制armeabi-v7a中的库，则需要在application.mk中添加APP_ABI := armeabi armeabi-v7a后，则会同时复制armeabi armeabi-v7a的库
