Didn't find class "org.webrtc.WebRtcClassLoader".

[WuxySZ]

There is a runtime error: Didn't find class "org.webrtc.WebRtcClassLoader".
Currently, there is a livekit. org. webrtc. WebRTC ClassLoader package available,
so where do I need to fix the C and CPP or Headerfile code? thank you!

same issue, how can I solve this problem ?

I compiled this fork and prefixed it (m125_release branch ) ,it occurs that question.
And according to the description of readme , this is my own compile step:

ah ,last update,

it's a long way to find out the solution, you don't need to compile like the doc : https://github.com/webrtc-sdk/libwebrtc 's readme,but ,you can use this repo : https://github.com/webrtc-sdk/webrtc-build ,it has docker scripts ,all you need is to run in docker;
in my case,i need to modify code for support h264, so I can run scripts in manual, includes actions below:

• clone deopt-tools
• clone webrtc-sdk ,and switch to a specified commit
• apply patchs
• apply my own changes
• run build_aar.py
  and then, you will get what you need , be happy !
