Android app development using Kotlin

As of 2025, Android holds over two-thirds of the global mobile operating system market. Approximately 72% of all smartphones and gadgets worldwide operate on Android. In CIS countries, this figure reaches up to 60%. That is why Android OS is prioritized during the app development process.

The process of Android app development consists of several main stages:

1. Find out what the user needs and set goals
2. Write a technical plan and create a user flow map
3. Design and development
4. Test and publish the app.

Options for Android App Development

For any business or startup, the app must be easy to use, work fast, and have clear design and simple navigation. These things help users enjoy the app and make it successful. To reach this, it’s important to choose the right programming languages and technologies. For Android, developers can use:

• For creating the Android UI (visual interface or frontend), the Kotlin language is used for native development, and JavaScript can be used within frameworks such as React, Vue, or Angular.
• For the backend (app logic and data management), the choice is broader. Depending on technical requirements, available human resources, and project budget, developers can use PHP, GO, Python, Node.js, Kotlin, or Java.
• For database management, SQL, NoSQL, or cloud platforms (such as Google Firebase, AWS Amplify) can be used to leverage broader capabilities.
• Cross-platform frameworks, such as React Native and Flutter (which uses Dart), are also popular and trendy. They enable developers to build applications for Android, iOS, and desktop environments using a single codebase.

Which Programming Language to Choose?

You’ve likely heard of Java, which for many years was the foundational language for Android app development. Many large-scale projects and banking systems are still based entirely on Java. However, in recent years, Google has officially declared Kotlin as the preferred language for Android development. This is no coincidence. Kotlin is convenient, fully compatible with Java, concise, and secure.

While there’s much to say about Kotlin's technical and practical benefits, here are the key arguments:

1. Powerful, simple, and fully compatible with Java
2. Safe and lets you write shorter code
3. Capability to expand application functionality without complex manipulations
4. Official integration with Android Studio   

Choosing programming languages and technologies is only half the work. No matter which tools you select, it is very important to ensure clean work, well-structured code, full testing, and ongoing maintenance.If you are working with a software development company, make sure to clearly include these requirements in the contract and technical documentation. Also, request a fixed warranty period for post-launch support.
