Android app development is a specialized field within software engineering dedicated to creating applications for mobile devices running the Android operating system. These devices include smartphones, tablets, smart TVs, watches, and other digital wearables.

Launched in 2003 as an open-source project, Android has evolved into a globally popular operating system. This app development process for this system involves leveraging extensive APIs to overcome mobile device limitations, incorporating services to enhance user experiences, and accessing free resources to accelerate and improve results.

Developers employ various programming languages like Java and Kotlin to conduct Android app development. Though Java still enjoys widespread use, Kotlin is touted by many experts as the programming language of the future for the Android platform.

As of 2023, Android has a global market share of around 70%. Hence, developing apps for this operating system is potentially lucrative.
