Message 335137 - Python tracker

3.7 added `sys.getandroidapilevel()` under #28740.  As Xavier mentioned in msg271439, that was used for subprocess.Popen in #16255 and also merged as part of 3.7.

I'm not sure if there is still interest in adding a `default_shell` to the os module using `sys.androidapilevel()` and the last batch that Xavier uploaded in 2016.
