py4android

A simple Python3 script to build Python static libraries for Android.

Of cause, by applying some changes easily, it would also work for shared libraries.

Tested on macOS 10.15 with NDK-r21 for Python 2.7.x.

If you dont work on macOS, you might have to change BUILD and NDK_TOOLCHAIN defined at front.

Usage

> python3 py4android.py [-h] [--api API] --version VERSION ARCH [ARCH ...]

Build Python for Android.

positional arguments:
  ARCH               currently supports: armeabi-v7a armv8a x86 x86_64

optional arguments:
  -h, --help         show this help message and exit
  --api API          specify Android API level (default 21)
  --version VERSION  specify Python version string (directory Python-<VERSION> must exists at this working path)
  • Download py4android.py along with Python source code
  • Unzip your Python-<VERSION>.tgz to Python-<VERSION> (within the same directory)
  • Hit commands like: python3 py4android.py --api 21 --version 2.7.14 armeabi-v7a armv8a x86 x86_64

    assuming you have define ANDROID_NDK_ROOT in your environ

  • Wait for compilations done, might take a while
  • If everything works fine. The include files could be found at prebuilt/android/<VERSION>/include, and the (static) libraries could be found at prebuilt/android/<VERSION>/libs/<ARCH>/libpython.a
