Attached test_socket.txt is the output of running 'python -m test -v test_socket' on android API 24. The 108 tests in error are UDPLITE tests introduced in issue bpo-37345.

Not interested anymore in android stuff.

Also, isn't this just a permissions error? I wouldn't think that would indicate a failure of the feature, but instead one of the testing environment.

Yes, this was probably caused by running the tests within an app which didn't have the INTERNET permission. With the permission present, I've confirmed that the UDPLITE tests all pass on the current main branch.

@encukou: So I think this issue can be closed.

Actually, I can reproduce this now on API level 21:

"avc" is an SELinux log message, so it looks like UDPLITE is blocked on older versions of Android. I'll update #116674 to deal with this.
