Android Developer

One million computer programming jobs are estimated to be created in the U.S. by 2020 - as well as 700,000 in Europe - thanks to unprecedented growth in the tech sector.

Here at OpenClassrooms, we pinpoint the key skills needed for the most in-demand jobs and develop courses and diplomas to train our students in those areas. That’s why we've developed a one-year bachelor’s-level diploma in development, which you can complete entirely online with the help of a dedicated mentor. 

In this path, you'll study Android development. Android developers build mobile applications on the most widely-used mobile platform in the world. You guessed it: Android! They build apps that run on both smartphones and tablets and can even run on Android smartphones or TVs.

Android is a mobile operating system created by Google. You may also have heard of its main competitor: iOS, which is made by Apple. Android is similar in terms of functionality but looks different and runs on different types of phones. 

An Android developer: 

• Builds mobile applications on the Android operating system
• Writes clean, well-structured code
• Writes unit and integration tests for their code
• Takes project briefs from clients and builds apps based on those needs 
• And more!

How much will I earn?

Android developers, whether they work in Java or Kotlin, can be well-paid because the industry lacks specialized developers in this field.

As an Android developer, you'll be able to earn:

United States

• Beginner: $60,000 - $80,000
• More experienced: $80,000 - $120,000+
• Freelance: $30 - $150/hour

United Kingdom

• Beginner: £35,000 - £45,000
• More experienced: £45,000 - £60,000+
• Freelance: £20 - £130/hour

What are my job prospects?

Android developers are actively recruited by every kind of company, from startups to big companies. Google products are widely used in almost every industry, and no company that ventures into web or mobile services would be able to do so fully without building Android applications, as Android is the most widely-used mobile platform in the world.
