Convert Pygame code to android apk

In this article we compile python pygame code to android apk using p4a (python for android) and buildozer

Pygame Car game source code on github and compile apk link check out for testing

Step 1 - 

Here we need to load audio and images or assests file with obsolute path then it will correctly load on android , if your game using any assets file then do this as below example 

# your imports

import os

img = os.path.abspath('path/to/img')

audiofile = os.path.abspath('path/to/wavfile')

screen.blit(img, obj_loc)

mixer.music.load(audiofile)

Use os.path.abspath(args) method to load assets file in game

Step 2 - 

Also make your game responsive that fits on mobile phone screen height width if needed

And make sure your main code file name is main.py, Everything is ready to compile,

Compile it where you want ie Google colab or Github action or on local computer.

In this article we will use google colab now

Extra - You can use kivy and Pyjnius code too in pygame code to access android api like gyro, storage and more

also you can use all pypi module that work with p4a in your game

Step 3 - 

Click on this link - https://colab.research.google.com/drive/16wji2BWd5HHlp7eNqBBcZONCxxCzV-jy?usp=sharing and this link open online google workspace for you, which have all neccesory command are written, click on file icon to upload game code on it as example given below

Step 4 -

Click on upload icon to upload source code as example given below

Step 5 -

Now run each cell command one by one (ctrl+enter or click on square bracke`[ ]`)) which are shown in image given below 

Step 6 -

Click on Buildozer init command this will generate buildozer.spec file which used to mention app name, app icon, android permissions, and modules more (explore this file yourself)

Generated buildozer.spec file, customize it or play with it

Include file extention name that you are using in code 

for example text file is .txt and audio file .wav (or any other that are not here mentioned) which are not listed on source.include_exts line number 16 buildozer.spec file

example -

# (list) Source files to include (let empty to include all the files)
source.include_exts = py,png,jpg,kv,atlas,wav,txt

Include pip moduls that used in code if you're using any extra module,

These moduls and their version are needed to compile successfully code please add this in line number 40 buildozer.spec file in requirements fields

python3==3.10.12,kivy==2.3.0,pyjnius==1.5.0,hostpython3==3.10.12,pygame

example - 

# (list) Application requirements
# comma separated e.g. requirements = sqlite3,kivy
requirements = python3==3.10.12,kivy==2.3.0,pyjnius==1.5.0,hostpython3==3.10.12,pygame

Step 7-

Run final command buildozer android debug

Enter y and now further this will ask you to accept google license, accept these and this process will take 15 to 30 minute for first time to compile

*sometimes colab page may become upresponsive which is normal you can leave it come back some time later

After successful compilation apk file will be produced in bin directory

Step 8 -

Download the apk and install on android device, and if it crashes then use adb tool to debug it and fix and compile again

Your Pygame will be successfully compiled for Android apk (in distributable form) 

Hope it helps you to bring your game on android

Happy coding
