How to Develop a Mobile App Using Python: A Beginner’s Guide

You cannot think of this era without mobile apps. People have used applications for personal use, business, or entertainment since childhood. Developing an app is difficult, especially for newbies. However, with the release of one of the easiest and most versatile languages, Python, it is easier to start.

This guide will teach you how to develop a mobile app for Android using Python. It will also explore why Python is a perfect choice for developing mobile apps and explain its advantages over other programming languages. Let's look into it. 

What is Python?

Python is a programming language developed and interpreted in late 1980 by Guido van Rossum. High-level programming, readability, and usability attracted developers from the first few lines when this clean code resulted in efficient lines. It supports multiple programming paradigms that are object-oriented, functional, and procedural.

The idea of Python was born in 1989 when its creator, Guido van Rossum, faced the ABC language's shortcomings, namely extensibility. Rossum started working on a new language that would integrate all good features of the ABC language and new desired features, such as extensibility and exception handling. Released was Python 1.0 in 1994; the module system came from Modula-3. The capability for interacting with an operating system, that of Amoeba, and functional programming tools accompanied this version.

In 2000, the core developers of Python transferred to Beopen.com. Several improvisations arrived in October of the same year when Python 2.0 came out, including a garbage collector and support for Unicode.

Python 3.0 was released in December 2008, abandoning backward compatibility and designed anew to eliminate duplicative constructs and modules. It is still a multi-paradigm language that offers developers the options of object orientation, structured programming, and functional programming.

Python today has many implementations, including Python, coded in Java language for Java Virtual Machine; IronPython, coded in C# for the Common Language Infrastructure; and PyPy version coded in RPython and interpreted into C. To be observed, CPython, coded in C and implemented by Python Software Foundation, remains the default and the most popular implementation of Python. These implementations work well in the native language they are written in, but they can also interact with other languages through modules. Most of these modules work based on a community development model and are free and open-source.

The syntax is clean, and the comprehensive libraries are now extensively used in web development, data science, AI, and mobile application development.

Why is Python the Best Choice for Mobile App Development?

Traditional methodologies with mobile applications involved using languages such as Java, Swift, or Kotlin. But with Python, the process can be much more simplified, and developers can avail of several benefits:

1. Beginner-friendly syntax

Unlike C++ or Java, Python does not require developers to mess around with complicated syntax and memory management. Thus, it streamlines the application process, allowing new developers to spend more time building functionality than debugging syntactic errors.

2. Versatility and Flexibility

Python is versatile and can be easily applied in all contexts. From a simple calculator to an application with more business features, it does well at any task. Developers can build a native application on either Android or iOS or a hybrid application that works decently across most platforms.

3. Cross-Platform Frameworks

Python has a lot of frameworks specifically targeted for mobile application development. Among the most used frameworks are Kivy and BeeWare, with which you can write once to deploy on multiple platforms. Thus, you do not have to write code specific to Android and iOS, saving time and money.

Kivy: An open-source Python library that supports multi-touch and is highly customizable. It's perfect for building Android and iOS apps with dynamic interfaces.

BeeWare: Another Python framework that supports building apps for multiple platforms, including Android, iOS, Windows, and macOS. BeeWare allows you to write native apps using Python.

4. Integration with AI and Data Analytics

Python is one of the favorites of data scientists and AI experts. Suppose your mobile app needs AI features like predictive analytics, machine learning, or natural language processing. In that case, it's easy to include those features into your app using the powerful libraries TensorFlow and PyTorch, developed with Python.

5. Strong Community and Resources

Python has some of the most gigantic and vigorous communities of developers. If you want tutorials or a library, plenty of those can be found online. On top of it, its open-source nature has thousands of free libraries to support and further your development tasks.

How can I develop a mobile app for Android with Python?

Now that we understand why Python is a fantastic tool for developing mobile applications, let's take a step-by-step approach to creating an Android application using Python.

1. Preparation of the Development Environment

Download some frameworks for developing mobile applications if you have not done that yet.

Kivy: It is the most used framework to develop Android applications using Python and can be installed easily using a single command line command in the terminal: pip install kivy

BeeWare: BeeWare can be considered the alternative to Kivy if one develops a native look-and-feel application across different platforms.

An IDE is an integrated development environment in which one writes and controls code. The most notable IDEs are PyCharm, Visual Studio Code, and Sublime Text.

2. Design of the App User Interface

Now that you've installed your environment, you can create your user interface. Kivy offers tools and widgets (such as buttons, sliders, and labels) that make creating your custom interface easy.

Use Kv, the domain-specific language of Kivy, to create your app's layout and style.

3. Developing the Core Functionality

Now that the UI is laid out, it is time to start implementing the core functionality of your app. For instance, if you build a to-do list app, you will find the logic for adding, deleting, and editing tasks accordingly. If it is either app, how do we fetch weather data from a certain API for display to an end user?

4. Testing Your App

Testing is a fundamental part of application development. Various testing frameworks available for Python, such as unit tests, make the testing process automated and simpler.

Test your application on different screen sizes and resolutions with Android Emulators. You should not leave behind testing on real Android devices also so that your application functions exactly as you expect it to in the real world.

5. Packaging and Deploying the App

Once your app is fully constructed and well-tested, you can package and deploy it. Kivy, for instance, allows you to compile your app into an APK you can install on any Android device using Bulldozer. Otherwise, you could use Briefcase (with BeeWare) to package your app and create a distributable APK.

You can then upload your app to the Google Play Store or distribute it privately to your users.

Types of Apps That Can Be Developed Using Python

Python's versatility allows you to create a wide range of apps. Here are just a few examples:

Entertainment Apps: Use Python to create streaming media, games, or interactive experience apps.

Social Media Apps: Build apps that support social networking features, chat rooms, and more.

Business Apps: Develop project management, time tracking, invoicing, and CRM apps.

Educational Apps: Develop educational tools, quizzes, and learning resources.

Healthcare Apps: Health-tracking apps or medical record management apps can be developed using Python.

AI-Powered Apps: If you're interested in more complex features, such as machine learning or 

chatbots, then Python is your go-to.
