The Future of Mobile App Development: Key Programming Languages

The future of mobile app development will be bright for a few reasons. First, all devices tend to become more and more portable. Second, these devices become technically competitive with local machines. And third, the technical stack for developing new mobile applications gets wider and wider because of unlimited demand for the whole mobile ecosystem. 

So, if you’re also interested in mobile development or looking to learn programming languages, we have some advice to help you make the right choice. 

Revolutionizing Mobile App Development: Top Languages

Our top list of popular programming languages is as follows:

  • Java
  • Swift
  • Kotlin
  • JavaScript
  • C++
  • Python

Each language has its strengths, areas of application, and different coding styles. Get your programming homework done with CodingHomeworkHelp if you’re already studying one of them and want to improve your coding skills. 

Let’s make a quick tour of the peculiarities of each language for mobile development we’ve mentioned. 

Java: The Time-Tested Choice for Android Development

Java remains the bread and butter for most mobile developers from every corner of Android app development, known for its object-oriented structure that facilitates organized and modular programming. 

This dinosaur of programming languages stays strong even when facing new languages’ emergence, with its’ rich API, extensive library support, and widespread usage across the Android ecosystem. If you’re at the beginning of your mobile app development journey, you may use Java as a reliable option for the stability and scalability of Android apps.

Swift and Kotlin: Modern Approaches to iOS and Android

Swift, designed by and for Apple, has become the go-to language for iOS development. It’s popular thanks to the safety features, efficient error handling, and the most comfortable IDE—Xcode, as most developers say. If you’re looking for the best-fit tool for the creation of iOS apps, then Swift’s readable syntax and robust performance will become your favorite.

Kotlin is a twin brother recommended by Google for Android app development. Most developers choose it for its concise syntax, interoperability with Java (which is extremely valuable in our cross-platform world), and ease of use. Yes, even if you’re not so masterful with coding, you can create modern, maintainable Android apps​ using this language with ease.

Emerging Popularity: JavaScript, C++, and Python in Mobile Apps

These giants will not steal the popularity of the existing programming languages for mobile app development, but they will extend the possibilities and cover a wide range of tasks related to the challenging limitations of other languages.

The Role of JavaScript in Cross-Platform Development

Cross-platform development saves money and time for digital products of all kinds. JavaScript’s versatility through frameworks like React Native enables the creation of cross-platform apps that run on both iOS and Android from a single codebase. This approach offers a significant advantage in development efficiency and app consistency across platforms​​.

Python: Beyond the Web into Mobile App Innovation

Python, a versatile language, also has its perks for mobile development. Frameworks like Kivy and BeeWare allow developers to use Python to create cross-platform mobile apps. Learning this language will make you more than a mobile app developer, as it’s widening your spheres of coding expertise.

C++: Powering Performance-Critical Mobile Apps

C++ will fit perfectly for performance-critical applications, such as games or apps requiring high-efficiency calculations where it’s essential to deliver optimized performance across platforms. The language’s conjunction with Android’s Native Development Kit (NDK) enables developers to create apps that offer superior performance optimization and user experience​​.


Why is Java considered a robust choice for Android app development?

The main reason is hidden in the object-oriented programming capabilities, extensive library support, and rich API techniques. Java’s platform-independent nature allows developers to code once and run it on any device that supports the JRE, which is a must for complex Android applications that require reliability, scalability, and cross-platform functionality​​​​. For example, consider a simple Android application developed in Java that displays a greeting message to the user. The code snippet below illustrates how Java’s syntax and Android SDK work together seamlessly:

public class MainActivity extends AppCompatActivity {


    protected void onCreate(Bundle savedInstanceState) {



        TextView greetingTextView = findViewById(;

        greetingTextView.setText(“Welcome to our Java-based Android app!”);



In this example, MainActivity extends AppCompatActivity, a fundamental building block for Android apps provided by the Android SDK, which is predominantly Java-based. The code sets the content view to display a layout defined in XML and uses Java to find a TextView by its ID and set its text property.

How have Swift and Kotlin changed the landscape of mobile app programming?

First and foremost, Swift and Kotlin became developer-friendly alternatives to Objective-C and Java, respectively. For example, using Swift’s powerful Array and Dictionary types along with closure syntax for operations like filtering or mapping is much easier than the same functionality in Objective-C. The Android community welcomed Kotlin for its concise syntax, interoperability, and many efforts from Google’s side in its growth as the preferred language for Android.

Both languages have made mobile app development more accessible and efficient for any level of coding, enabling developers to create high-quality apps faster and with less effort.
