Android is the most popular mobile operating system in the world, making it important to learn for any software application developer. In contrast to Apple’s iOS, which can only be used in iPhones, Google’s Android operating system is open source, which allows it to be used by manufacturers all over the world. As a result, now Android powers 2.5 billion phones, tablets, and other smart devices of all sizes, configurations, and price points, making it the operating system of nearly 75% of the world’s mobile devices.

Android app development uses Android Studio, the Integrated Development Environment (IDE) for Android apps. Within Android Studio, developers can choose to use common object-oriented programming languages like Java, Kotlin, and C++. The ability to use Java in particular can make Android app development easier than iOS development for programmers coming from a desktop software background. That said, the Swift programming language used in iOS requires writing less code, which generally makes iOS development faster and easier for experienced mobile developers.‎

Because Android devices are so popular, a background in building apps for this operating system is essential for any mobile app developer. This is especially true for developers of apps for the global market; while iOS devices are actually slightly more popular in the U.S., the availability of a wide range of Android devices from international manufacturers at significantly lower price points than iPhones has made this OS more popular in every other global market - and especially in Asia.

Becoming a mobile software developer with Android skills is a path to a high-paying job in a fast-growing industry. According to the Bureau of Labor Statistics, software developers earned a median annual wage of $107,510 in 2019, and these jobs are expected to grow much faster than the economy-wide average over the next decade.‎
