The same error occurs also in issue 26936.
msg266362 lists the conditions under which getaddrinfo() fails on Android.
With this patch, the test succeeds on both Android API levels 21 and 23 (there is no level 22).

test_create_connection_service_name does not fail on android-24-x86_64.

Is the test still failing on the master branch of Python? Is the patch still needed?

According to my last post on this issue 2 years ago, this test "does not fail on android-24-x86_64". This means that it does not fail on API level 24. IMO the issue may be closed.

Ok, thanks Xavier. If someone has an issue with test_asyncio on Android, either reopen this issue or open a new issue ;-)
