@happeecoder This the patch is only for armeabi-v7a and arm64-v8a. Nox player is x86 so the patched apk will not work.
Actually to bypass in x86 since Tiktok is only using okhttp you can simply use this script Universal Android SSL Pinning Bypass with Frida.

Here is an article that shows how to use that:

can you suggest any android emulator which supports arm64-v8a or armeabi-v7a ?
Because I cant find TikTok x86 apk

@happeecoder the tiktok apk is universal so it works on architecture including x86 so there is no specific apk for x86.

About the emulator using arm or arm64 this would be hard if your pc is not arm. I assume your using windows so probably not. You can try the official android emulator which has some arm system images but I doubt it will work.

@happeecoder it seems like I was actually wrong there isn't x86 build for the new versions of tiktok. The reason why it's opening on Nox Emulator is because they use ARM translation to run arm instructions.

I was able to create a patched apk which is working on Nox Emulator x86.
