Best practices for building mobile apps with Python and Kotlin

The development of mobile applications has become an important trend in today's technology field. Python and Kotlin are two of the most popular programming languages ​​currently used for web development and mobile application development respectively, and are also considered two of the best practice languages ​​for building mobile applications.

In this article, we’ll cover best practices for building mobile apps using Python and Kotlin, and provide guidance from choosing a programming language to building your app.

Choose a programming language

Both Python and Kotlin have their unique advantages in mobile app development.

Python is a high-level programming language that is flexible and easy to read. It can handle various data types with ease and excels in web scraping, data mining, and artificial intelligence. We can build mobile applications using Python through various frameworks such as Kivy and Pygame or mobile application development platforms such as Kivy Buildozer and BeeWare.

Kotlin is a modern programming language specifically used for mobile application development, developed by JetBrains in 2011. It has the benefits of Java, but also adds many new features and syntax, such as extension functions and properties, lambda expressions, and null safety. At present, the usage of Kotlin has surpassed other languages ​​such as Ruby, Scala and Go, becoming the officially supported development language of Android.

So, if you need to process large amounts of data or need applications that use artificial intelligence capabilities to analyze data, Python may be a good choice. But if you want to develop more heavyweight mobile applications and only need to handle small amounts of data, Kotlin is recommended.

Integrated Development Environment (IDE)

Before choosing a programming language and starting building mobile applications, we need to choose a good integrated development environment (IDE). IDEs help developers improve productivity and code readability, and improve the quality of developing mobile applications.

For Python, we can use various integrated development environments such as PyCharm, VSCode or Spyder. VSCode is a free lightweight text editor, while PyCharm and Spyder provide more tools and plug-ins to better support Python development.

For Kotlin, Android Studio is the most popular and powerful IDE. It is developed by Google and available for free. It provides a powerful code editor, advanced debugging capabilities and memory analyzer to help developers improve efficiency and quality when building applications.

Application Frameworks and Components

When building an application, we also need to consider what frameworks and components to use. Frameworks and components can improve development efficiency, avoid duplication of effort, and shorten application development time.

Python’s mobile application frameworks mainly include Kivy and BeeWare. Kivy is a cross-platform framework for developing mobile applications based on Python and Cython using a custom OpenGL ES 2 renderer that is easy to customize. BeeWare is a Python project for creating mobile, desktop and web applications. BeeWare provides a component library called Toga for mobile applications that can create multi-platform user interfaces and provides various tools and plug-ins.

For Kotlin, the Android SDK provides a series of tools and components to help developers build mobile applications. The most popular of these is Android Jetpack, which is a set of components that help developers write cleaner, more maintainable code and provides APIs and tools to help deal with common problems.

Testing and Debugging

Testing and debugging are crucial when building mobile applications. This helps ensure the quality of your application and reduce errors. We need to test the application by running unit and integration tests on the code, while using debugging tools and profilers to identify and resolve errors.

For Python, we can use testing frameworks such as pytest or unittest to write and run tests. Python also provides the pdb module, which is a debugger for Python that helps developers debug code.

For Kotlin, Android Studio provides rich integration testing and unit testing frameworks, such as JUnit, Espresso, and UI Automator. Advanced debugging features and memory analyzers are also provided to help developers quickly locate and solve problems.

Conclusion

Building mobile applications using Python and Kotlin requires many considerations, from choosing a programming language to an integrated development environment, from application frameworks to code testing and debugging. When deciding which programming language to use, you need to make your choice based on the goals and functional features of your application.

With the rapid development of mobile applications, Python and Kotlin remain one of the best practice languages ​​for building mobile applications. By understanding and following these recommendations, developers can more easily build high-quality and powerful mobile applications.
