Android App Development

Android App Development is the process of creating applications for devices running on the Android operating system, including smartphones, tablets, and wearables. As a specialized field of mobile application development, it leverages computer science principles to build, test, and deploy software using the Android Software Development Kit (SDK). Developers typically use programming languages like Kotlin or Java within the official Android Studio integrated development environment (IDE) to design user interfaces, manage data, interact with device hardware, and handle the application's lifecycle, with the ultimate goal of distributing the final product through app stores like the Google Play Store.
