Currently, sys.platform and are equal to 'linux' on Android. While Android uses the Linux kernel, the operating system is not a regular Linux. The libc (bionic) is very different than the regular glibc, the filesystem is organized very differently, etc.

I propose to change sys.platform and to 'android' when running on Android.

Wait, is 'posix' on Android. That's fine in fact. Only sys.platform should be updated.

The idea was first discussed on python-dev:

me: "It seems like sys.platform == 'android' would be more appropriate
since Android is not Linux: different libc, different filesystems,

Brett Cannon: "I've had a similar thought myself.".

A similar change was proposed by pmp-p on MicroPython:

His use case is to use ffi module on Android (see the PR for more information), currently ffi fails to locate libraries.

I propose to leave MACHDEP unchanged: keep MACHDEP="linux". Can it create inconsistencies? Is it an issue in practice?

My short term goal is to use sys.platform == 'android' has the reference test to check if we are running on Android.

Sadly, I failed to find anyone to help me on this issue and I lost interest on supporting Android, so I just close the issue. Sorry.
