What languages to learn become an Android developer

Posted on

To become an Android developer, there are several programming languages and technologies you should consider learning. Here are the key ones:

  1. Java: Java has been the traditional language for Android development and is widely used for creating Android apps. It provides the core foundation for Android development and allows you to leverage the Android SDK (Software Development Kit) and other resources.
  2. Kotlin: Kotlin is a modern programming language that has gained popularity for Android development. It is fully interoperable with Java, meaning you can use Kotlin alongside Java in your Android projects. Kotlin offers concise syntax, null safety, functional programming features, and other improvements over Java.
  3. XML (eXtensible Markup Language): XML is a markup language used to define the layout and structure of user interfaces in Android apps. Understanding XML is essential for designing and building user interfaces using Android’s XML-based layout files.
  4. SQL (Structured Query Language): SQL is a language used for managing and querying databases. Android apps often need to interact with databases to store and retrieve data. Learning SQL will help you work with SQLite, which is the default database engine used in Android.
  5. JavaScript: While not strictly required, having knowledge of JavaScript can be beneficial for developing Android apps. It can be useful for web-based components, hybrid app development using frameworks like React Native, or integrating web technologies into your Android projects.
  6. Gradle: Gradle is a build system used for building and managing Android projects. It’s crucial to understand the basics of Gradle to compile your code, manage dependencies, and configure your project.
  7. Other web technologies: Depending on the specific requirements of your Android app, you may also need to learn HTML, CSS, and JavaScript frameworks like React or Angular for web-based components or WebView integration.

Remember that Android development encompasses more than just programming languages. Familiarity with Android Studio (the official IDE), Android SDK, Android APIs, and other relevant tools and frameworks will also be valuable in your journey as an Android developer.

It’s worth noting that while Java has been traditionally used for Android development, Kotlin has been gaining significant adoption and is now officially supported by Google. Kotlin offers modern features and is often preferred for new Android projects. Therefore, it may be a good idea to focus on Kotlin, while still having a basic understanding of Java, especially if you plan to work with existing Java-based Android codebases.
