Android App Development Languages: Complete Guide for Beginners (2026)

Introduction

In the tech sector, creating Android apps has emerged as one of the most sought-after and popular skills. With billions of Android users globally, developers are always creating apps that enhance communication, business, entertainment, and daily living.
Programming languages are the building blocks of all Android applications. Because it impacts the user experience, development time, scalability, and performance of the app, language selection is essential.
The best Android app programming languages, their capabilities, and benefits, and when to use them are all covered in this thorough guide.

What are Android app development languages?

Programming languages called Android app development languages are used to make apps for Android-powered gadgets, including tablets, smartphones, and smart TVs.

These languages help developers:

• Write app logic
• Design user interfaces
• Manage data
• Integrate APIs and services

Why Choosing the Right Language Matters

Selecting the right programming language is important because:

    ✔ Improves app performance

    ✔ Reduces development time

    ✔ Enhances scalability

    ✔ Simplifies maintenance

    ✔ Supports modern features

Top Android App Development Languages

1. Kotlin

A popular current statically typed programming language for creating Android apps is Kotlin. Because of its ease of use, security, and robust capabilities, it has emerged as the language of choice for developing Android applications and is officially supported by Google.
After Google declared Kotlin as an official Android language in 2017, it immediately became well-known. Nowadays, Kotlin is used to create the majority of contemporary Android apps.

Kotlin, which runs on the Java Virtual Machine (JVM), was created by JetBrains. Because of its complete compatibility with Java, developers can write code in Kotlin while utilizing pre-existing Java libraries and frameworks.

Basic Kotlin Example

Here is a simple Kotlin program:

fun main() {
    println("Hello, Android!")
}

Explanation:

• fun is used to define a function
• main() is the entry point
• println() prints output

2. Java

Java is one of the main programming languages used for Android app development. It was the first programming platform that Google supported for creating Android apps. Java supports developers in managing various Android app components, controlling user interactions, and creating app logic.

Simple Java Example in Android

</> Java

package com.example.myapp;

import android.os.Bundle;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        System.out.println("Hello, Android using Java!");
    }
}

Explanation:

• MainActivity is the main screen of the app
• onCreate() runs when the app starts
• The message is printed when the app launches

 3. Dart

With the support of the Flutter framework, Dart, a contemporary programming language created by Google, is mostly utilized to create Android applications. Developers may create cross-platform apps that run on iOS, Android, and other smartphones by using Dart in Flutter instead of writing native Android code.

Simple Dart Example (Flutter)

void main() {

  print("Hello, Android using Dart!");

}

Flutter UI Example:

import 'package:flutter/material.dart';

void main() {

  runApp(MyApp());

}

class MyApp extends StatelessWidget {

  @override

  Widget build(BuildContext context) {

    return MaterialApp(

      home: Scaffold(

        appBar: AppBar(title: Text("Dart Android App")),

        body: Center(

          child: Text("Hello Android using Dart!"),

        ),

      ),

    );

  }

}

Explanation:

• main() is the starting point
• runApp() launches the app
• Text() displays content on screen
• Flutter uses Dart to build UI

 4. JavaScript

A well-liked programming language, JavaScript is mostly used to produce dynamic and interactive web content. It is frequently used for both front-end and back-end development utilizing environments like Node.js, and it operates in web browsers.

Simple JavaScript Example

</> JavaScript

console.log ("Hello, World!");

Web Page Example:

<!DOCTYPE html>

<html>

<head>

  <title>JavaScript Example</title>

</head>

<body>

<h1>JavaScript Demo</h1>

<button onclick="showMessage()">Click Me</button>

<script>

function showMessage() {

  alert ("Hello from JavaScript!");

}

</script>

</body>

</html>

Explanation:

• console.log() prints output in the console
• alert() shows a popup message
• JavaScript is used inside <script> tags
• The button triggers a function when clicked

 5. C++

Although it is not the main language used to create Android apps, C++ is often employed for components of apps that require high performance. The Android NDK (Native Development Kit) allows C++ to have used with Android.

Flow like Java/Kotlin → JNI → C++ → Back to Android app

Simple Example of C++ in Android

Step 1: C++ Code (native-lib.cpp)

#include <jni.h>
#include <string>

extern "C"
JNIEXPORT jstring JNICALL
Java_com_example_myapp_MainActivity_stringFromJNI(JNIEnv* env, jobject) {
std::string hello = "Hello from C++!";
return env->NewStringUTF(hello.c_str());
}

Step 2: Call C++ from Java

public class MainActivity extends AppCompatActivity {

    static {

        System.loadLibrary("native-lib");

    }

    public native String stringFromJNI();

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

       

        String text = stringFromJNI();

        System.out.println(text);

    }

}

 6. Python

With the use of specialized tools and frameworks, Python can be utilized to create Android apps even though it is not an official language for Android development. Backend logic, automation, and simple apps are its primary uses.

Example (Calling Python from Android):

</>Python

# Python file (script.py)

def add(a, b):

    return a + b

</>Java

Python py = Python.getInstance();

PyObject result = py.getModule("script").callAttr("add", 2, 3);

System.out.println(result.toInt());

Output:- 5
