HTTP2 not working with different mixes of library and OS versions
See original GitHub issueIn my application I’m still using branch 3.12.x because I still need to support older versions than Android 5.0. Today I’ve realized that HTTP2 connections were not working on Android 10.
Here you can find the log from a Caddy server with different requests made by my app. The only differences between executions were the modification of OkHttp version. I’ve tried from an old 3.12.x version where HTTP2 were working fine to the latest version of that branch, 3.14.x and 4.x

In summary for Android 10:
- In 3.12.x it was working fine until 3.12.9 were it does not work anymore.
- In 3.14.x it seems not to work at all.
- In 4.x it seems to work properly from 4.2.0 till the latest one.
I’ve also tried the same test with an Android 9 device. These are the relevant log parts.

In summary for Android 9:
- 3.12.x is working fine
- 3.14.x is not working
- In 4.x the behavior is the same as in Android 10. HTTP2 is not woking until 4.2.0 and it’s working fine from that.

@niltsiar I don’t intend to fix either issue. There are potential code fixes we could do, but unless someone else wants to agree the path forward and implement one of them, it’s not something I have motivation to do given work, family in lockdown and given the risk/reward of doing fixes like this on maintenance branches.
Closing this umbrella issue, follow up on the specific issues.
BTW you are an Awesome OSS collaborator, really appreciate the time you put into investigating this!
Nice analysis.
