How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Kotlin developer with Android Studio with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Kotlin
What is Kotlin developer?
A developer in Kotlin, will be responsible for planning, design and development of apps and software using Kotlin. They will contribute at all stages of the development lifecycle and test and make necessary changes in features.
Kotlin developers make sure the designs are compliant with the specifications received, write efficient and well-designed code, and analyze, test and help with the integration of applications. Developers analyze software and solve applications and software problems that use Kotlin tools. They need to manage application development and support the improvement of it, such as detecting problems and suggesting technologies.
They also tune apps and systems for higher performance – squeezing out every bit of speed, finding opportunities for improvement – from code optimizations to feature additions when needed; to software updates.
Responsibilities of a Kotlin developer:
- Planning, designing and developing apps and software using Kotlin
- Contributing in all phases of the development cycle
- Testing and amending features when needed
- Ensuring that designs comply with specifications provided
- Writing well-designed and efficient code
- Analyzing, testing and assisting with the integration of applications
- Conducting software analysis
- Troubleshooting applications and software
- Managing application development
- Supporting continuous improvement of applications
- Investigating and suggesting technologies
- Optimizing apps and systems
- Identifying opportunities for improvement
- Optimizing code
- Adding new features
- Providing software updates
Kotlin vs Java
Kotlin does pretty much everything Java does, but does it better.
It’s more lightweight, more elegant, and more terse than Java, at least in terms of authoring data classes and callbacks. It’s also much safer, with null safety built-in as a major talking point.
The only concrete pro of Java over Kotlin is that Java is used more, and most of the documentation examples for Android are also in Java. For complete beginners, to learn Java is actually a slightly smoother ride. But that isn’t because Java is better, so this is hardly a reason at all.
Even though it’s tempting to pit them against each other in a cage match, Kotlin and Java compile to the same bytecode, so they can be used together in a single project.
This is why many experts believe they’ll coexist. At least for the time being.
Cross-Platform Development
Kotlin is a general-purpose programming language, which can be used for any type of development, including the server-side and client-side web, Android, and iOS. The reason why we can share code between different platforms in Kotlin is due to the fact that the language runs on JVM.
Flexibility
So by letting developers choose the style of their choice, Kotlin is as flexible as it gets: it is a multifaceted language combining functional and objective-oriented constructs, and it delivers on the improved programming experience.
Reduced Programming Time
Another of Kotlin’s advantages is that it removes all code which is repeated, and in addition, this language is very compact, concise and this in turn means that the writing process of the code is optimised, avoiding all repetition.
Skills of a Kotlin Developer:
- Expert knowledge in Kotlin and Java
- Hands-on experience with software development and app design
- Knowledge of databases
- Familiarity with web frameworks like GWT
- Proficiency in object-oriented fundamentals
- Strong backend programming skills
- Experience with SQL
- Knowledge of web development solutions
- Familiarity with XML basics
- Being informed on new language developments
- Having business knowledge of the industry they want to work in
- Strong communication skills
- Ability to work well in a team
Where is Android Studio used?
App-tastic Laboratory!
- Mad scientists (ahem, developers) use Android Studio to concoct delightful app potions for Android smartphones, adding a dash of Java or a sprinkle of Kotlin to the mix.
Virtual Sandbox Extravaganza
- It’s like a digital playground where coding kiddos (professionals, really) build virtual sandcastles (aka apps), then knock ‘em down (debug) until they're sturdy.
Romancing the Droid
- Matchmaking UI designers with UX developers, Android Studio plays Cupid, ensuring users swipe right on slick, intuitive app interfaces.
Widget Whizzbang!
- Where widget wizards wave their wands (write code) to create tiny taskmasters (widgets) that live on home screens, helping muggles interact with apps at a glance.
Android Studio Alternatives
Visual Studio Code with Android Extensions
Visual Studio Code (VS Code) is a lightweight but powerful source code editor that runs on desktop. It comes with built-in support for JavaScript, TypeScript and Node.js, with a rich ecosystem for other languages such as C++, C#, Python, PHP, and Java. For Android development, it relies on extensions such as 'Android for Visual Studio Code' which allow developers to build, run, and debug Android applications.
// Sample command in VS Code to start Android emulator
> adb start-emulator -name Pixel_XL_API_30
- Fast and lightweight
- Highly customizable with extensions
- Great for polyglot programming
- May require multiple extensions for full functionality
- Less integrated compared to Android Studio
- Debugger setup less straightforward
IntelliJ IDEA
IntelliJ IDEA is an integrated development environment (IDE) written in Java for developing computer software. It is developed by JetBrains and is available in two editions: a community edition that is open-source and a commercial edition. It provides robust support for Android development, especially when considering its capability to manage complex code bases and its suite of powerful refactoring tools.
// Example of Android activity in IntelliJ
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
- Comprehensive Java/Kotlin support
- Powerful code analysis and refactoring tools
- Seamless version control integration
- Relatively high memory consumption
- Can be overwhelming for new users
- Community version lacks some Android-specific features
Eclipse with ADT Plugin
Eclipse is a multi-language software development environment comprising an integrated development environment (IDE) and an extensible plug-in system. It was the main IDE for Android development before Android Studio. With the Android Development Tools (ADT) plugin, Eclipse provides the necessary functionality for Android app development.
// Sample Eclipse shortcut to open declarations
F3 - Open Declaration: Jump to the declaration of the selected class, method, or variable.
- Large pool of plugins
- Works well for Java and C/C++
- Extensive community and history
- Perceived as outdated for Android development
- Slower build process compared to Gradle/Android Studio
- Less intuitive UI/UX design features
