Android Jni調用so庫，加載庫失敗分析

現有一個項目，通過JNI接口調用底層庫，例如：lib***.so

如下所示，總是加載不成功。調試發現，每次加載so庫，會跳到catch異常處理部分，然後打印異常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工具發現有些函數未定義，如下所示：

2、係統函數，暫時還沒找到合適的解決辦法，正在努力尋求方法。
