Who is an Android developer?

Android is the leader among operating systems worldwide with a huge number of supported devices. To start developing mobile applications on this OS, you need to know Java, but Kotlin is also better, and the median salary of such a specialist is 140 thousand rupees. Together with the Android-developer of the Maxim taxi and the mentor of the course "Android-developer" Arina Murasheva answered the main questions about the profession.

What does an Android developer do?

It creates and maintains applications on the Android operating system. It works not only smartphones, but also tablets, smart watches, as well as Smart TVs. It depends on the developer how convenient and functional the application will be.

A specialist in mobile development not only creates the architecture of the application, but also makes a convenient user interface, tests the application, works with the API (Application Programming Interface).

Android-developer creates applications for devices on the Android operating system. He writes code, works on the interface and design, tests the application and fixes bugs, and also adapts it for different models of devices (of which Android has a great many).

Where is an Android developer needed and how much in demand?

The pandemic has accelerated the transition of businesses online, and the growth of e-commerce and related areas continues, and business owners are striving to reach as large an audience as possible by creating applications for both iOS and Android. Application developers are actively sought in marketing, retail, banking, transport aggregators, hotel business, education, sports and games.

According to statcounter at the beginning of 2021, the share of Android among mobile devices in the world was 74.34% (this is about 2.5 billion active devices).

As of June 2021, there were 1574 vacancies of android developer in India at the (against 1461 iOS developers). You can see the current state of the market by typing the name of the vacancy into any job search engine.

How much does an Android developer get?

According to the Study of Habr Careers, the median salary of a mobile developer in India is 140 thousand rupees. An Android developer with 1-2 years of experience in India receives an average of about 120 thousand rupees per month.

A middle specialist can receive from 100 thousand rupees a month, and a signor and a team leader on average from 180 thousand rupees.

Pros and cons of the profession


  • Android has a high entry threshold and a huge variety of devices, so there is always a job for such a specialist.
  • This OS has open source and a wide community, so you can always get help and find the answer to your question on the forums.
  • Prospects and demand - Android-developer will not be left without work, as applications are needed by businesses from a variety of areas.
  • You can work for yourself - there is an opportunity to make a convenient schedule yourself. In addition, developers can take several orders at the same time and increase their income.

Arina Murasheva:

"You see the result of your work. Of the minuses - Chinese phones, which also need to be supported. "


  • The variety of devices is also a minus, since you have to adapt applications for different devices, and it is almost impossible to take everything into account.
  • If Apple every year releases detailed guidelines for application development, then Android's development nuances may change, and not all libraries and answers on the forums will be relevant.

Which is better: Android or iOS?

Android is loved for its open source and accessibility, but scolded for the abundance of different devices. iOS is praised for transparent OS updates and a small number of smartphones, but is not liked for the high prices of devices. What to choose - everyone decides for himself.


In fact, the variety of devices for Android is a plus: you do not need any additional equipment - you can write code on any operating system (macOS, Linux or Windows). But for development on iOS, you will definitely need equipment from Apple.

What do you need to know and be able to do?

Android Developer Starter Pack:

  • File structure and operating principles of the operating system.
  • XML and Android SDK.
  • Programming languages Java or Kotlin.
  • Android Studio is a development environment where you write code.
  • Network protocols are sets of rules and standards that define commands and how devices communicate. There are quite a lot of protocols, the main ones are HTTP, HTTPS, TCP/IP.
  • Basics of design and engineering of mobile applications.
  • SQL is a language for communicating with databases in order to be able to work with them.
  • Git is a distributed version control system and GitHub is a web service for hosting IT projects and collaborative development.

What kind of soft skills are needed?

In mobile development, as in development in general, it is necessary to be able to communicate with colleagues and customers. "I work in a fairly large company," says Arina Murasheva, "so the ability to negotiate and work in a team is always necessary. Here, each person is responsible for certain tasks and you have to communicate a lot. "

Another important skill is the ability to Google and ask questions on time. "I did not understand - look in the documentation, Google, read the articles, look at the books. And if there is no result, it's time to seek help from colleagues, "advises Arina.

If I change my mind, can I switch from Android to iOS?

Yes, you will only need to master the Swift programming language, study Apple's documentation and other development tools, for example, iOS Console (iOS Console Magazine Viewer for macOS) and Hyperion (a solution to improve the design), etc. There are also developers who are engaged in cross-platform development and make applications that function on both platforms. In any case, the skills of mobile development on one platform will be useful in working on another and you will not have to learn everything from scratch.

How do I get started?

You can download the Android Studio development environment for free from the website. True, if you have 4 GB of RAM on your computer, the environment will take up most of it.


For Android development, Java and Kotlin are used, both are object-oriented – respectively, you need to know the principles of OOP.

You can start learning Java and Kotlin from video tutorials, books and manuals, while studying the official documentation for Android.

You'll also have to understand the HTTP and REST architectural styles that help applications interact with other applications and servers.

Then you should understand the file structure and how the operating system works. The developer should know how to optimize the application, understand how the file system communicates with other applications. You also need to understand the life cycle of the application and its interaction with the operating system.

After that, you can move on to the basics of design and engineering mobile applications, the principles by which navigation works and graphic elements are arranged. Android has guidelines for the development of the interface for this.

When you're comfortable, write your own little app, post it on GitHub, and publish it on Google Play. Then try to master popular libraries such as Glide, Retrofit, and Room.

You can take free courses on Coursera, attend webinars and read books. Another option to quickly pump skills is to participate in a hackathon, a championship in mobile development. The hackathon from Android Academy takes place, for example, on Habra.

On the course "Android-developer" SkillFactory can go all the way from scratch to creating your application in 16 months (already in the 8th month you will have a junior level). You will learn the principles of OOP, Java Core, multithreading, design patterns and start thinking algorithmically. We give skills in the format of practice: you will work out the material on simulators, interactive webinars, end-to-end and team projects.

In parallel with the training, we will prepare you for technical interviews, help you determine your career goal and create a resume. Our Career Center will accompany you throughout the program and help you find a job afterwards.
