菜鸟关于 Cydia Substrate 的问题

[chenqh]

现象

日志提示: can not find libnative-lib.

C++代码

#include <jni.h>
#include "substrate.h"
#include <android/log.h>
#include <unistd.h>
#include <stdio.h>
#include <fcntl.h>
#include <sys/types.h>

	return _dvmLoadNativeCode(soPath,classLoader,detail);
}
char* (*getFromNativeString) (void);

char* newhello(void)
{	static char str[] = "hello better tomorrow";
//    return "hello better tomorrow from cqh";
	return str;
}

//Substrate entry point
MSInitialize{
    LOGD("Substrate initialized.");
//    LOGD();
    MSImageRef image;
    image = MSGetImageByName("/data/app-lib/zcgames.com.cynativeexample-1/libnative-lib.so"); // ¾ø¶Ô·¾¶
    if (image != NULL)
    {
    	LOGD("dvm image: 0x%08X", (void*)image);

        void * dvmload = MSFindSymbol(image, "createHello");
        LOGD("Search createHello");
        if(dvmload == NULL)
        {
            LOGD("error find createHello.");
        }
        else
        {	MSHookFunction(dvmload, (void*)&fake_dvmLoadNativeCode, (void **)&_dvmLoadNativeCode);
        //	MSHookFunction(dvmload,(void*)&newhello,(void **)&getFromNativeString);
			LOGD("hook createHello sucess.");
        }
    }
    else{
        LOGD("can not find libnative-lib.");
    }
}

app so 的路径为data/data/zcgames.com.cynativeexample/libnative-lib.so, 而在内存中的名字为

现在问题为什么问题提示找不到 library 呢 ？有大佬指点下吗？
