How to use docker to build kivy to android app

0. Example App

 git clone https://github.com/yingshaoxo/kivy-diary.git
 cd kivy-diary

1. Prepare your SDK

Use Android Studio SDK Manager to install it. Here I installed SDK 29 and NDK 21.

2. Pull p4a to local

 docker pull kivy/python-for-android

3. Run it (you need to change the first SDK path)

 docker run -it --name kivy --volume "$(pwd)":/home/user/host/app --volume /home/yingshaoxo/Android/Sdk:/home/user/host/Android/Sdk kivy/python-for-android

4. Active the virtual env

 source venv/bin/activate && cd ../host/app

5. Build it

use ./build.sh or

 export ANDROIDSDK="/home/user/host/Android/Sdk"
 export ANDROIDNDK="/home/user/host/Android/Sdk/ndk/21.0.6113669"
 export ANDROIDAPI="29"  # Target API version of your application
 export NDKAPI="21"  # Minimum supported API version of your application

 p4a apk --private . --package=xyz.yingshaoxo.kivydiary --name "KivyDiary" --version 0.2 --bootstrap=sdl2 --requirements=python3,kivy,jnius --blacklist-requirements=sqlite3,libffi,openssl --orientation=portrait --add-source . --presplash=./data/flash.png --icon=./data/icon.png --permission INTERNET --permission WRITE_EXTERNAL_STORAGE  --debug

6. Reuse it

 docker start kivy
 docker exec -it kivy /bin/bash
 source venv/bin/activate && cd ../host/app# author: yingshaoxo
