pydk : Android generic ( 4.4/32 api19 , 5+/64 api21) + emscripten tip of tree/incoming

PyDK (Python Developpement Kit) allows you to efforless build CPython , Panda3D and gives you prebuilt libraries ready to use pip modules and runtime loaders.

for use on :

  • Android starting with API19(kitkat 4.4)

  • Web browsers, Electron.

There's two gitter channels for support and general interest in supporting the platforms for cpython: for Android: https://gitter.im/Wasm-Python/pydk Browser: https://gitter.im/Wasm-Python/community

embedding is one part of the process and packaging is another : embedding is not specific to PyDK You are welcome to discuss how to improve Python embedding on mobile/web/wasi no matter which packager you prefer (Panda3D/Beeware/Kivy).

PyDK packaging ability is minimal, just enough to run tests. The main goal is and will remain building interpreter + extensions and support libs.

PyDK was made to make Python core adjustments easier Its next big step is to package only testsuites and provides local wheels.

pydk : Android generic ( 4.4/32 api19 , 5+/64 api21)

Requirements:
    * C-Python ® 3.6+ installed
    * clang/clang++ 8+ full build env <- this is very important.
    * git, wget, patch
    * android-sdk + android-ndk 21 or 23
    * all Panda3D requirements
    * about 16 GiB free disk space
    * 4 GiB MEM-SWAP for panda3d linking

( for debian/ubuntu/mint maybe just have a look at the .github/workflows/blank.yml CI apt-get lines )

Clone this repo and go into folder pydk

add sdk as "android-sdk" and ndk as "android-sdk/ndk-bundle" (ndk21 or 23) in the folder, symlink is ok too

Tehen launch :

ARCHITECTURES="armeabi-v7a arm64-v8a x86 x86_64" ./pydk-all.sh

use PYMINOR/PYMICRO to pick the CPython version ( look in sources.* for what's available as i'm often dragging behind )

To launch step by step use instead for eg CPython 3.7.13 :

STEP=true ARCHITECTURES="armeabi-v7a arm64-v8a x86 x86_64" PYMINOR=7 PYMICRO=13 ./pydk-all.sh

NOTE: now has limited pip support and will detect your ./projects/*/requirements.txt. and will do its best to package them for an android apk.

You can also use pip-cross via the various venv shell.[ARCHITECTURE].sh (to be sourced) ( when in the shell you have python3-xxxxxx and pip3-xxxxxx cross compiler scripts )

NOTE: an emscripten android project emulation is actually brewing. it allows deploying your apk untouched in browsers.
