Understanding the mobile app development process is necessary and a strategic advantage for entrepreneurs, startups, and developers. It enables them to create apps that cater to a broad audience by considering screen sizes, hardware requirements, and other factors. Also, it helps them stay ahead of the curve in the swiftly growing mobile app development industry. Become indispensable to any company with an online mobile app development course from industry experts.

⃣ Librerías y Frameworks: Android Views y Jetpack Compose

This section teaches you how to create your own functions, use default values for parameters, and even pass functions around. You’ll also learn about lambdas, which are short, anonymous functions for special situations. This part teaches you how to install Kotlin on different systems (Windows, macOS, Linux) and set it up with an easy-to-use tool called IntelliJ IDEA. IntelliJ makes coding in Kotlin smooth and fast, as it has built-in features for writing and testing Kotlin code.

You need to understand the essential syntax and features of this language such as variables, classes and functions. Don’t forget that Kotlin interoperates Java so Kotlin also includes OOP concepts such as inheritance, polymorphism, and encapsulation on itself. These concepts are fundamental to Android app development and will help you write clean and organized code. Don’t forget that writing clean and organized code will increase your productivity as a developer. Part 4 explores design patterns and architecture, which, while valuable, is relatively less critical than foundational Android knowledge.

  • We’ve revisited the five-part Android Developer Roadmap series and evaluated whether the knowledge it covers is still relevant, given the time since its initial release.
  • Kotlin also include Lot of new features and libraries that is not present in Java.
  • This can be confusing, as most cross-platform frameworks provide UI components or layers that enable building screens with a unified codebase across different platforms.
  • The Android Developer Roadmap was created to guide developers — especially juniors — who are unsure where to start or what to focus on to become better Android developers.
  • The initial release aims to provide a user experience comparable to the existing Objective-C export, while overcoming the constraints of Objective-C.

Java was developed by Sun Microsystems (now the property of Oracle) and one can use Microservices with Java. It is a featured language focused to provide interoperability, safety, clarity, and tooling support. Since its inception in 2010, developed at IntelliJ IDEA has been originated by JetBrains. A deep dive into why Result is not ideal for handling errors in application code and how Either offers a better approach.

  • So we recommend only reading the sections that would be helpful to you.
  • Now it is the longest and the most important part of becoming an Android developer.
  • This blog is your comprehensive guide to drafting a robust mobile app development roadmap in 2025.
  • Over time, numerous solutions and tools have emerged to address development challenges, significantly improving Android projects.
  • The final part, Jetpack Compose, explores key topics including the Compose structure, Compose UI, State management, Side effects, CompositionLocal, and the migration strategy from XML to Jetpack Compose.

Multiplatform core

Setting up the development environment is the key of your building apps. Android Studio is the best because it includes Android SDK on itself initially but personally I prefer IntelliJ IDEA for development using Kotlin. As a language created by JetBrains, kotlin entwickler Kotlin gives better result on IntelliJ IDEA for me but Android Studio is a serious option for Android app development (obviously). Which one will you use as an IDE is up to you, exploring both of them will help your productivity and flexibility as well. In this article, you’ve explored Kotlin Multiplatform’s platform architecture, library ecosystem, and various solutions for Kotlin Multiplatform development. Kotlin Multiplatform shows great promise, with active support from JetBrains and Google, and a growing number of companies adopting it for production-level projects.

Now that you’ve started to build apps, you can build yourself a portfolio and start to getting recognized as an Android developer. You can create a showcase for your skills and experience to your potential employers and/or clients. Having a collection of functional and well-designed apps will demonstrate your capabilities as an Android app developer. You can also engage with the Android developer community for your recognition by joining online forums, discussion groups, and social media communities. Platforms like Stack Overflow, Reddit, LinkedIn and GitHub can provide support, learning resources, and opportunities for collaboration, thus helping your productivity. And in person, groups such as Google for Developers near you will lead you into better opportunities.

Whether you’re building Android apps, working on websites, Web development or developing backend systems, Kotlin has everything you need. By learning the basics, understanding Kotlin’s syntax, and setting up your development environment, you’re ready to start coding. As you explore more features of Kotlin, you’ll find it a flexible and rewarding language that opens up many exciting development opportunities. Kotlin is a modern programming language that works on the Java Virtual Machine (JVM) and can be used alongside Java.

Loading images from the network is essential in modern mobile development for displaying user profiles, thumbnails, and more. However, rendering UIs differs across platforms like Android and iOS, requiring a solution that supports both Kotlin Multiplatform for core functionality and Compose Multiplatform for UI integration. Kotlin Multiplatform (KMP) is another rising star in cross-platform development driven by the collaboration between JetBrains and Google.
