Building spaCy for arm-v8a using python-for-android:

docker buildx build ./build-env --tag p4a/build-env
docker buildx build ./bundle    --tag p4a/spacy
docker run -v p4a-build-cache:/root/.ccache -v p4a-build-output:/root/.local/share p4a/spacy
# To use a local recipe folder (e.g. if it is not yet submitted), also include
# -v /path/to/local/p4a-recipes:/root/bundle/local_recipes

Then for the target platform you can grab:

• python-bundle;
• modules;
• site-packages;
• stdlib.zip;
• etc.

from the p4a-build-output docker volume.

You can customize the build with Docker's --build-args:

For the build-env image:

• "p4a_tarball_url=https://github.com/kivy/python-for-android/tarball/develop"
• "android_sdk_platform_version=27";
• "android_sdk_cmdline_tools_version=8092744" (taken from https://dl.google.com/android/repository/commandlinetools-linux/...);
• "android_sdk_build_tools_version=32.0.0";
• "android_ndk_version=23.1.7779620";

For the bundle image:

• The p4a recipe set to use ("recipe_tarball_url=https://github.com/F1uctus/p4a-recipes/tarball/4c487202b2a2ef5d18f8bfdd9b7c50a946e52865")
• The python version (e.g. "python_version=3.10.4");
• The target packages to build (comma-separated, "requirements=spacy,etc");
• The minimum supported Android SDK version ("min_android_api=24").
