How to develop Android app completely using python? [closed]

I would like to develop a (rather simple) android app to be distributed via Play Store. I would like to do so completely in python. However, the online research hasn't quite enlightened me: most comments are either outdated (>1 year old, and I feel there might be better integration of python since then) or they talk about running python in android (e.g. here).

Therefore, I'm looking for information regarding the questions:

• is it feasible to develop an App completely in python - and what are the tools to do so? (Is e.g. Kivy recommendable?)
• if so: what are the best software environments to implement this? (I unsuccessfully tried using Android Studio but couldn't figure out a way to run python code there.)

I'm quite new to app development and would highly appreciate any leads of doing this in python rather than in Jave etc., which I don't know yet.

Many thanks for you help in advance.

To answer your first question: yes it is feasible to develop an android application in pure python, in order to achieve this I suggest you use BeeWare, which is just a suite of python tools, that work together very well and they enable you to develop platform native applications in python.

checkout this video by the creator of BeeWare that perfectly explains and demonstrates it's application

How it works

Android's preferred language of implementation is Java - so if you want to write an Android application in Python, you need to have a way to run your Python code on a Java Virtual Machine. This is what VOC does. VOC is a transpiler - it takes Python source code, compiles it to CPython Bytecode, and then transpiles that bytecode into Java-compatible bytecode. The end result is that your Python source code files are compiled directly to a Java .class file, which can be packaged into an Android application.

VOC also allows you to access native Java objects as if they were Python objects, implement Java interfaces with Python classes, and subclass Java classes with Python classes. Using this, you can write an Android application directly against the native Android APIs.

Once you've written your native Android application, you can use Briefcase to package your Python code as an Android application.

Briefcase is a tool for converting a Python project into a standalone native application. You can package projects for:

• Mac
• Windows
• Linux
• iPhone/iPad
• Android
• AppleTV
• tvOS.

You can check This native Android Tic Tac Toe app written in Python, using the BeeWare suite. on GitHub

in addition to the BeeWare tools, you'll need to have a JDK and Android SDK installed to test run your application.

and to answer your second question: a good environment can be anything you are comfortable with be it a text editor and a command line, or an IDE, if you're looking for a good python IDE I would suggest you try Pycharm, it has a community edition which is free, and it has a similar environment as android studio, due to to the fact that were made by the same company.

I hope this has been helpful

You could try BeeWare - as described on their website:

Write your apps in Python and release them on iOS, Android, Windows, MacOS, Linux, Web, and tvOS using rich, native user interfaces. One codebase. Multiple apps.

Gives you want you want now to write Android Apps in Python, plus has the advantage that you won't need to learn yet another framework in future if you end up also wanting to do something on one of the other listed platforms.

Here's the Tutorial for Android Apps.

Android, Python !

When I saw these two keywords together in your question, Kivy is the one which came to my mind first.

Before coming to native Android development in Java using Android Studio, I had tried Kivy. It just awesome. Here are a few advantage I could find out.

Simple to use

With a python basics, you won't have trouble learning it.

Good community

It's well documented and has a great, active community.

Cross platform.

You can develop thing for Android, iOS, Windows, Linux and even Raspberry Pi with this single framework. Open source.

It is a free software

At least few of it's (Cross platform) competitors want you to pay a fee if you want a commercial license.

Accelerated graphics support

Kivy's graphics engine build over OpenGL ES 2 makes it suitable for softwares which require fast graphics rendering such as games.

Now coming into the next part of question, you can't use Android Studio IDE for Kivy. Here is a detailed guide for setting up the development environment.
