Configuring Kivy p4a on macOS

Install Android Studio.

Android SDK will be located at $HOME/Library/Android/sdk.

Install Temurin8:

brew install --cask temurin8
export JAVA_HOME=/Library/Java/JavaVirtualMachines/temurin-8.jdk/Contents/Home

Set the following environment variables:

export ANDROID_SDK_ROOT="$HOME/Library/Android/sdk"
export NDK_VERSION=25.2.9519653
export SDK_VERSION=android-33

Add path to sdkmanager to PATH:

export PATH=$ANDROID_SDK_ROOT/tools/bin:$PATH

Install Android SDK and NDK from https://developer.android.com/ndk/downloads/ or with Android SDK Manager:

echo "y" | sdkmanager --install "ndk;$NDK_VERSION" --channel=3
echo "y" | sdkmanager --install "platforms;$SDK_VERSION"

Create new Python virtual environment:

python3 -m venv .venv
source .venv/bin/activate

Install p4a:

pip install python-for-android

Install Cython:

pip install --upgrade cython

Run p4a with --requirements including your custom Python libraries, like numpy in the following example:

p4a create --requirements numpy --arch arm64-v8a --arch armeabi-v7a --arch x86_64 --sdk-dir $ANDROID_SDK_ROOT --ndk-dir $ANDROID_SDK_ROOT/ndk/$NDK_VERSION --dist-name serious_python

Choose No to "Do you want automatically install prerequisite JDK? [y/N]".

When p4a command completes a Python distributive with your custom libraries will be located at:

$HOME/.python-for-android/dists/serious_python

Location of hostpython3:

~/.python-for-android/build/other_builds/hostpython3/desktop/hostpython3/native-build/python3

.so files:

~/.python-for-android/dists/serious_python/libs

Header files:

~/.python-for-android/build/other_builds/python3/arm64-v8a__ndk_target_21/python3/Include
