Android (operating system)Android is a mobile operating system developed by Google, based on a modified version of the Linux kernel and other open source software and designed primarily for touchscreen mobile devices such as smartphones and tablets. In addition, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface. Variants of Android are also used on game consoles, digital cameras, PCs and other electronics.
Android developers build mobile applications on the most widely-used mobile platform in the world. 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!
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.

At OpenClassrooms, learning is project-driven because that’s the fastest way to become proficient. Projects offer hands-on experience so you can hit the ground running when you start your new job.
iPhone Operating System
iOS (formerly iPhone OS) is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that presently powers many of the company’s mobile devices, including the iPhone, iPad, and iPod Touch. It is the second most popular mobile operating system globally after Android.
