Are you thinking about making an Android app but not sure which programming language to use? You’re not alone! This is a common question for beginners and even experienced developers. There are many programming languages out there, and choosing the right one can be confusing.
In this blog, we will explain everything in simple words. We will look at the most popular programming languages used for Android app development. We will also help you understand the benefits of each so you can decide which one is best for you.
What Is Android App Development?
Before we dive into programming languages, let’s understand what Android app development means.
Creating Apps for Android Phones
Android app development is the process of making software or applications that run on Android devices, like smartphones and tablets. Android is an operating system developed by Google and used by many phone makers like Samsung, Xiaomi, OnePlus, and more.
Why Android Apps Are Popular
Android is the most widely used mobile operating system in the world. Millions of people use Android phones every day. That’s why building Android apps can be a great opportunity if you want to start a career or a business in the mobile app world.

Why Choosing the Right Language Matters
When you make an Android app, you need to write code. The code tells the phone what to do. You write this code using a programming language.
Choosing the right language is very important. It affects:
- How easy it is to write your app
- How fast your app works
- How much help and tools are available
- How easy it is to learn for you
Let’s now explore the best programming languages you can use for Android app development.
Top Programming Languages for Android Development
We will go through the most popular programming languages for Android app development. For each one, we will explain:
- What it is
- Why people use it
- Pros (good things)
- Cons (not-so-good things)
- Who should use it
Let’s start!
Kotlin – The Official Language by Google
What is Kotlin?
Kotlin is a modern programming language. It was created by a company called JetBrains. In 2017, Google announced that Kotlin is the official language for Android app development.
Why Use Kotlin?
Kotlin is simple and clean. It helps you write less code and do more. It works perfectly with Java (another popular language for Android). Most new Android apps are now written in Kotlin.
Pros of Kotlin
- Easy to read and write
- Google officially supports it
- Works well with existing Java code
- Helps prevent common errors
- Has strong community and tools
Cons of Kotlin
- Can be harder for complete beginners
- Fewer online tutorials compared to Java
Who Should Use Kotlin?
If you want to build modern Android apps and learn a language that will last for many years, Kotlin is a great choice. It is best for beginners who are serious about Android development and are ready to learn something new.
Java – The Classic Choice
What is Java?
Java is one of the oldest and most well-known programming languages. It was the main language for Android development before Kotlin. Even today, many apps are still built in Java.
Why Use Java?
Java has been around for over 25 years. It’s reliable and powerful. Many companies still use Java to build Android apps. There are also tons of learning resources for Java.
Pros of Java
- Huge community support
- Tons of tutorials and guides online
- Works on many platforms
- Still used in many Android apps
Cons of Java
- Longer and more complex code
- Not as modern as Kotlin
- Can be harder to manage errors
Who Should Use Java?
Java is good if you want to understand the “roots” of Android development. It’s also a good choice if you plan to work in companies that still use Java. If you already know some Java, it will be easier to jump into Android development.
Dart (with Flutter) – For Beautiful and Fast Apps
What is Dart?
Dart is a programming language made by Google. It is used with a toolkit called Flutter. Flutter allows you to build apps for Android and iOS at the same time using one codebase.
Why Use Dart and Flutter?
Flutter is very popular because it helps you make beautiful apps with less effort. It’s fast, flexible, and supports many cool designs.
Pros of Dart and Flutter
- Build apps for both Android and iOS
- Great for modern user interfaces
- Huge growth in popularity
- Hot reload – see changes instantly
Cons of Dart and Flutter
- Dart is less known outside Flutter
- Larger app sizes
- Not as many jobs as Java/Kotlin (yet)
Who Should Use Dart and Flutter?
If you want to build apps for both Android and iOS, Flutter is a fantastic choice. It’s great for startups, personal projects, or people who love beautiful designs.
Python – Simple But Not Common for Android
What is Python?
Python is one of the easiest programming languages to learn. It is used in many areas like web development, data science, and automation.
Why Use Python for Android?
Python is not mainly used for Android, but there are tools (like Kivy or BeeWare) that allow you to make Android apps using Python.
Pros of Python
- Very easy to learn
- Great for beginners
- Large community support
Cons of Python
- Not officially supported for Android
- Fewer tools and features for mobile apps
- Apps may be slower or larger
Who Should Use Python?
Python is a good start for total beginners who want to learn programming. But if your main goal is Android development, you should switch to Kotlin or Java later.
C++ – For High-Performance Apps
What is C++?
C++ is a powerful programming language used for system-level programming, like making games or performance-heavy apps.
Why Use C++?
In Android development, you can use C++ for parts of your app that need high performance, like games or video processing.
Pros of C++
- Very fast and efficient
- Great for heavy tasks like games or graphics
- Works with Android through the NDK (Native Development Kit)
Cons of C++
- Harder to learn
- More complex to manage
- Not needed for most regular apps
Who Should Use C++?
Use C++ only if you are building apps that require a lot of speed or graphics, like a 3D game. For regular apps, it’s better to stick with Kotlin or Java.
JavaScript (with React Native) – Web Developers’ Favorite
What is JavaScript?
JavaScript is a popular language mainly used for websites. But with a framework called React Native, you can also use JavaScript to build mobile apps.
Why Use JavaScript and React Native?
React Native lets you build both Android and iOS apps using the same code. This saves time and effort. It’s perfect for people who already know web development.
Pros of JavaScript and React Native
- One codebase for both Android and iOS
- Many libraries and tools
- Huge community
Cons of JavaScript and React Native
- Apps may not run as fast as native apps
- Requires knowledge of web development
- Not ideal for heavy performance apps
Who Should Use JavaScript and React Native?
If you’re a web developer who wants to try mobile apps, React Native is a great start. It helps you use your web skills to build mobile apps quickly.

- Already Know Java: Continue with Java or start learning Kotlin.
- Want to Build for Android and iOS Together: Choose Dart and Flutter or React Native (JavaScript).
- Interested in Games or High-Performance Apps: Look into C++.
- Love Simplicity and Learning to Code: Try Python, but switch to Kotlin later for serious Android work.
Learning Tips for Android App Development
Here are a few tips to make your learning journey smoother:
Start Small
Begin with simple projects like a calculator or a to-do list app. This helps you learn the basics without feeling overwhelmed.
