The most obvious change would be to subprocess.Popen(). The reason a generic approach there won't work is also the reason I expect more changes might be needed: the Android file system doesn't abide by any POSIX file system standards. Its shell isn't located at /bin/sh, but at /system/bin/sh. The only directories it provides that are POSIX-standard are /dev and /etc, to my knowledge. You could check to see if /system/bin/sh exists and use that first, but that would break the preferred shell on POSIX systems that happen to have /system for some reason or another. In short: the preferred shell on POSIX systems is /bin/sh, but on Android it's /system/bin/sh. Simple existence checking might break the preferred shell on either. For more specific stdlib examples I'd have to check the test suite again.

FYI, /bin/sh is not POSIX, see http://bugs.python.org/issue16353#msg224514
