Android Jni调用so库，加载库失败分析

现有一个项目，通过JNI接口调用底层库，例如：lib***.so

如下所示，总是加载不成功。调试发现，每次加载so库，会跳到catch异常处理部分，然后打印异常log信息。

static{
	try{
		System.load("/data/data/com.***/lib/lib***.so");
	}
	catch(UnsatisfiedLinkError ulink){
		Log.i("HVnative====","Can not load library");
		ulink.printStackTrace();
	}
}

用arm-none-linux-gnueabi-ld工具发现有些函数未定义，如下所示：

如果“undefined reference to” 后面打印的函数是：
1、你自己写的函数，那么你应该去检查自己所写的这段代码有何问题，修改之后，再重新编译底层库；

2、系统函数，暂时还没找到合适的解决办法，正在努力寻求方法。
