Python 3 Android

This is an experimental set of build scripts that will cross-compile the latest Python 3 git master for an Android device.

Prerequisites

Building requires:

1. Linux or macOS. Ubuntu 14.04, Arch Linux and macOS Sierra tested.
2. Android NDK r14 beta 1 or above installed and environment variable $ANDROID_NDK points to its root directory. NDk r13 or below is not supported.
3. git and python3.7 in $PATH

Running requires:

1. Android 5.0 (Lollipop, API 21) or above
2. arm, arm64, x86, x86-64, MIPS or MIPS64

Build

1. make clean for good measure.
2. For every API Level/architecture combination you wish to build for:
   • Edit env to match your (desired) configuration.
   • make to build everything!

Installation

1. Make sure adb shell works fine
2. bash ./devscript/send.sh copies all files to /data/local/tmp/python3 on the device
3. In adb shell:

cd /data/local/tmp
. ./python3/tools/env.sh
python3.7m

And have fun!

SSL/TLS

SSL certificates have old and new naming schemes. Android uses the old scheme yet the latest OpenSSL uses the new one. If you got CERTIFICATE_VERIFY_FAILED when using SSL/TLS in Python, you need to generating certificate names of the new scheme:

python3.7m ./python3/tools/c_rehash.py

Check SSL/TLS functionality with:

python3.7m ./python3/tools/ssl_test.py

Known Issues

No big issues! yay
