Converting Python Kivy to Android APK using Google Colab

In this lecture we will learn to create .apk file of an Kivy based calculator application
The Google Colab Way!
The conversion requires a Linux environment and Google provides it for free! If you belong to Data Science or Deep learning background then you must be aware of this platform.
It provides you a virtual machine with 75GB space, 12GB RAM, and around 12GB GPU power! You can use this platform to perform model training, checking logs, or running Python codes.
As this is a Linux based system, now the only thing required is to install the dependencies and initiate the process.
Link to access the Google colab notebook:
colab.research...
You can directly use my colab notebook where you just need to run all the cells, that’s it!
a) !pip install buildozer
b) !pip install cython==0.29.19
c) !sudo apt-get install -y \
python3-pip \
build-essential \
git \
python3 \
python3-dev \
ffmpeg \
libsdl2-dev \
libsdl2-image-dev \
libsdl2-mixer-dev \
libsdl2-ttf-dev \
libportmidi-dev \
libswscale-dev \
libavformat-dev \
libavcodec-dev \
zlib1g-dev
d) !sudo apt-get install -y \
libgstreamer1.0 \
gstreamer1.0-plugins-base \
gstreamer1.0-plugins-good
e) !sudo apt-get install build-essential libsqlite3-dev sqlite3 bzip2 libbz2-dev zlib1g-dev libssl-dev openssl libgdbm-dev libgdbm-compat-dev liblzma-dev libreadline-dev libncursesw5-dev libffi-dev uuid-dev libffi6
f) !sudo apt-get install libffi-dev
g) !buildozer init
h) !buildozer -v android debug
i) !buildozer android clean
Before running the cells, make sure to upload your app code to the colab notebook and after running the bulldozer init command, make sure to edit the specs file generated and nothing else!
This is the easiest and most convenient way to build apps without the need for an actual system!

Hello bro I need a help
THANK YOU oh my goodness the forums try to make it sound impossible .. it's easier than blinking thanks to you! CHEERS!!
I was thinking of not using kivy mainly because of how people complain about turning it to a mobile app (saw an article of a guy who tried for 4 days and gave up). Going to give it a try after seeing this vid. I'm subscribing.

where is the .buildozer directory?
Hello, this worked but my app uses modules other than Kivy, and when converted to APK, the file cannot import these modules. How do I fix this? Thanks in advance.
Open the builder.spec file, there is a module section inside. If you write the module you use and the modules used by your module in that part, it will work.
You can see what the module is using by typing 'pip show [module name]' in cmd. I hope I have helped.
all first Sir
I tried using this but for some reason it is not working. I wrote my program in Python 3.11.4, Kivy 2.2.1 and Kivymd 1.1.1

Hello Sir,
Is it possible to make an iOS app from here i.e. Converting Python Kivy to an iOS app using Google Colab?
@@rolando1259 and you need to do it on a Mac too. Now I see why most developers don't like Apple
@@BlyatifulButter Easy to set and develop hard to distribute
@@rolando1259 exactly. "Hard to distribute" is the term I'm looking for. Windows and Linux's terminals have packages that can compile Python scripts into an .apk in like 5 lines of code. Hell, you can even develop iOS applications there with VirtualBox. Meanwhile, Macs can only make iOS apps and as far as I know, there is no Linux terminal support or Virtual Machine support (natively) for Mac, and even then, you have to get a valid license, unlike when compiling .apk files, where the ToS/TaC pops up and you simply click "Accept", free of charge. Apple sucks generally.
