tshirtman/buildozer repository overview

⁠What

A simple docker image to build kivy projects without pain (hopefully)

⁠How to use

⁠Buildozer.spec

If you don't have a buildozer.spec you can create one using

sudo docker run -v $PWD:/buildozer tshirtman/buildozer buildozer init .

Then customize it in your favorite editor.

⁠Building

Simply run the docker image with the directory containing buildozer.spec mounted as /buildozer/, the result apk will be in your directory/bin

sudo docker run -v $PWD:/buildozer/ tshirtman/buildozer

The first build, or any build since a change to your requirements in buildozer.spec will be slower, since the distribution has to be rebuilt (it's cached in your project's directory, so it'll be reused when possible). Builds that can reuse your distribution will be a lot faster.

⁠Installing

For buildozer to be able to install to your phone from docker, you need a few additional flags

sudo docker run --priviledged \
  -v $PWD:/buildozer/ \
  -v /dev/bus/usb:/dev/bus/usb \
  -v /etc/udev/rules.d/:/etc/udev/rules.d/ \
  tshirtman/buildozer buildozer android debug deploy run logcat

This command will build, install, run and display logcat for easier debugging

If you can't make it work, you'll need another way to deploy

• adb

  If you have adb installed on your machine, you can use

   adb install bin/yourapp.apk
  

  Copy

• webserver

  You can run a local webserver and open your application from the browser

   python -m SimpleHTTPServer 8000 bin
  

  Copy

  and open it on your phone

  http://your-ip:8000/bin⁠

  Of course, don't do that in an untrusted network if you care about the secrecy of your project, or the security of your computer :).

• MTP

  This is a bit less nice, but you can open the phone in your filebrowser, drop it on the phone, and open it with a file browser on the phone, to install it.

⁠Debugging

Ideally debugging should be done through "buildozer android logcat", but if you can't do it for some reason, I advise configuring kivy to output to a file on your phone memory, this can be achieved by setting the Config before any other kivy import in your main.py

from kivy.config import Config
Config.set('kivy', 'log_dir', '/mnt/sdcard/kivy_logs')

So you can open them from your file browser with your phone plugged to your computer.
