IMHO it's ok to skip a few asyncio tests on Android. It's safe if it doesn't touch the code of asyncio itself.

It don't really care if the Android version is not checked yet. Moreover, if we really want to check the version, we should check the *runtime* verison, not the *build* version of Android. We need the discussed platform.android_ver() function which doesn't exist yet. So it's fine to postpone the version check in asyncio tests.
