IL2CPP Problem Resolution

Open ZhouXinyu001 opened this issue 2 years ago • 4 comments

I have found the reason why IL2CPP faster runtime cannot run.

It is mainly due to the fact that System.Reactive.Subjects.Subject cannot be translated properly when full generic sharing is not supported in IL2CPP.

It is expected that UniRx (https://github.com/neuecc/UniRx) can be used to solve this issue.

in IL2CPP build socket.io couldn't connect to server without any error but when I updated my unity from 2021.x to 2022.3.20, problem fixed.

Hi, Big thanks for this bug search.

I did not do a deep search in socket.io client source code, but between the 3.0.6 and 3.0.8 versions they did some refactoring and they do not use Subscribe anymore. So this pending pull request, updateing library from 3.0.6 to 3.0.8, seem to fix this issue.

I changed my package.json in unity to use the forked repository and I'm now able to connect to my server in android.
