How to develop Android app completely using python

Question

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like to do so completely in python  However  the online research hasn t quite enlightened me  most comments are either outdated   1 year old  and I feel there might be better integration of python since then  or they talk about running python in android  e g  here    Therefore  I m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

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

There are two primary contenders for python apps on Android  Chaquopy  https   chaquo com chaquopy   This integrates with the Android build system  it provides a Python API for all android features  To quote the site  The complete Android API and user interface toolkit are directly at your disposal    Beeware  Toga widget toolkit   https   pybee org   This provides a multi target transpiler  supports many targets such as Android and iOS  It uses a generic widget toolkit  toga  that maps to the host interface calls    Which One   Both are active projects and their github accounts shows a fair amount of recent activity    Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms  If you have basic designs  and a desire to expand to other platforms this should work out well for you   On the other hand  Chaquopy is a much more precise in its mapping of the python API to Android  It also allows you to mix in Java  useful if you want to use existing code from other resources  If you have strict design targets  and predominantly want to target Android this is a much better resource

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
