[FunctionCallObfuscate] Failed to replace a call to function

[xiangzhai]

Hi @Naville

Testcase: dl.c build.sh

$ cat SymbolConfig.json 
{
  "Java_com_tencent_mm_network_Java2C_getNetworkServerIp": "Java_com_tencent_mm_network_Java2C_XXX"
}

Failed to replace because my misunderstanding?

It's already implemented in dlsym in your test case so there is no function to replace?

[xiangzhai]

Sorry my misunderstanding!

But I have a requirement from KISS ARE about Obfuscate JNI library

Replace Java_com_tencent_mm_network_Java2C_getNetworkServerIp -> Java_com_tencent_mm_network_Java2C_XXX

Then use the JNI library in Android project, the function name is obfuscated :)

[Naville]

Feel free to create a PR. I personally have zero experience with Android stuff

[xiangzhai]

Because Android Phone is much cheaper than iPhone, and it doesn't need to buy expensive MacBookPro :)
