Note: Scores indicate relative strengths in specific criteria and are not an absolute ranking for general Android development.
2.1. Kotlin – The official Android language
Kotlin has been Google’s preferred language for Android development since 2019. Its concise syntax, null safety, and interoperability with Java have made it the first choice for most modern Android projects. In 2025, Kotlin for Android app development continues to evolve with strong tooling support, seamless integration with Jetpack Compose, and compatibility with Kotlin Multiplatform, enabling developers to share business logic across multiple platforms.
For example:
fun main() {
println(“Hello Android World”)
}
The table below presents the pros and cons of Kotlin:
| Pros | Cons |
| – Concise and expressive code, reducing boilerplate
– Null safety features that mitigate runtime errors – Full support and endorsement from Google – Strong cross-platform potential through Kotlin Multiplatform |
– Slightly slower compilation speed compared to Java in some cases
– Smaller talent pool than Java, which can make hiring experienced Kotlin developers harder in certain regions – Some older Android libraries still require additional work to integrate seamlessly |
2.2. Java
Java has been the foundation of Android development since its inception. It is robust, stable, and supported by one of the largest developer communities in the world. Although Kotlin has taken the lead in new projects, Java remains critical for maintaining legacy applications and large-scale enterprise systems.
For example:
public class HelloWorld {
public static void main(String[] args) {
System.out.println(“Hello Android World”);
}
}
The table below presents the pros and cons of Java:
| Pros | Cons |
| – Mature ecosystem with vast libraries and frameworks
– High stability and backward compatibility – Excellent for large enterprise applications |
– More verbose compared to Kotlin
– Lacks some modern language features |
2.3. Dart with Flutter
Dart powers the Flutter framework, enabling developers to create high-performance, cross-platform applications from a single codebase. It is ideal for projects that need rapid deployment on Android and iOS.
For example:
void main() {
print(‘Hello Android World’);
}
The table below presents the pros and cons of Dart:
| Pros | Cons |
| – Single codebase for multiple platforms
– Hot reload for faster UI development – Strong performance for UI-intensive apps |
– Less mature ecosystem compared to Kotlin and Java
– Some native integrations may require additional effort |
2.4. C++ with Android NDK
C++ is used in Android development for performance-critical components through the Android Native Development Kit. It is common in game development, AR/VR, and applications requiring heavy computation.
For example:
#include <iostream>
using namespace std;
int main() {
cout << “Hello Android World” << endl;
return 0;
}
The table below presents the pros and cons of C++:
| Pros | Cons |
| – Exceptional performance for computation-heavy apps
– Direct control over system resources – Ideal for game engines and AR/VR projects |
– Complex syntax and memory management
– Requires integration with Java or Kotlin |
2.5. Python for Android
Python is not a native Android language but is supported via frameworks like Kivy, BeeWare, and Chaquopy. It is mainly used for prototyping, educational purposes, or specialized applications that integrate Python libraries.
For example: print(“Hello Android World”)
The table below presents the pros and cons of Python:
| Pros | Cons |
| – Very beginner-friendly
– Extensive libraries for AI, data science, and backend integration – Great for proof-of-concept apps |
– Limited native performance
– Smaller ecosystem for Android-specific tools |

2.6. C# with Xamarin and Unity
C# is widely used for Android development in two main areas: cross-platform business applications through Xamarin and game development with Unity. It offers strong integration with Microsoft’s development tools.
For example:
using System;
class Program {
static void Main() {
Console.WriteLine(“Hello Android World”);
}
}
The table below presents the pros and cons of C# with Xamarin and Unity:
| Pros | Cons |
| – Ideal for developers in the Microsoft ecosystem

– Xamarin ecosystem is smaller than Android-native tools |
2.7. JavaScript with React Native
JavaScript is the foundation of React Native, one of the most popular frameworks for building mobile apps using web technologies. Developers can reuse code between Android, iOS, and the web.
For example: console.log(“Hello Android World”);
The table below presents the pros and cons of JavaScript:
| Pros | Cons |
| – Large developer community
– Rapid development and code reuse – Strong ecosystem of plugins |
– Performance may lag compared to fully native apps
– Requires bridging for certain device features |
2.8. HTML and CSS with Hybrid Frameworks
HTML and CSS are used in combination with JavaScript in hybrid frameworks such as Ionic or Apache Cordova. They allow web developers to transition into mobile app development.
For example:
<!DOCTYPE html>
<html>
<body>
<p>Hello Android World</p>
</body>
</html>
The table below presents the pros and cons of HTML and CSS with Hybrid Frameworks:
| Pros | Cons |
| – Easy transition for web developers
– Can reuse existing web assets – Suitable for content-driven apps |
– Lower performance compared to native development
– Limited access to advanced device features |
2.9. Lua with Corona (Solar2D)
Lua, used in the Corona SDK (now Solar2D), is a lightweight scripting language ideal for 2D mobile games. It offers fast development and good performance for small to medium-scale projects.
For example: print(“Hello Android World”)
The table below presents the pros and cons of Lua:
| Pros | Cons |
| – Lightweight and fast for 2D games
– Simple syntax for beginners – Built-in physics engine |
– Primarily for game development
– Smaller community than mainstream Android languages |
2.10. TypeScript for React Native
TypeScript, a superset of JavaScript, brings static typing to mobile app development with React Native. It improves code reliability and maintainability, making it a strong choice for larger projects.
For example:
import { Text } from ‘react-native’;
const App: React.FC = () => <Text>Hello Android World</Text>;
The table below presents the pros and cons of TypeScript:
| Pros | Cons |
| – Type safety reduces runtime errors
– Better scalability for complex projects – Large community and library support |
– An additional compilation step compared to JavaScript
– Learning curve for those new to typed languages |
