Android
Android is a comprehensive software stack of mobile devices that includes an operating system, middleware, and key application. This mobile platform is primarily used for creating applications and games for Android devices, testing them in a simulator, and then deploying them on various devices such as mobile devices and tablets.
Mastering Android means developing a strong understanding of programming languages used for Android app development, like Java and Kotlin, and the Android Software Development Kit (SDK) which includes Android libraries and developer tools. A strong grasp of the Android Studio, which is the official Integrated Development Environment (IDE) for Android app development, is an essential part of mastering this skill.
In terms of requirements by employers, they will typically expect a deep understanding of the Android ecosystem and the latest trends, the ability to code in Java and/or Kotlin, understanding of Android APIs, and thorough proficiency with the Android SDK and Android Studio. Potential employers would also look for experience with restful APIs to connect Android applications to back-end services, understanding of Google's Android design principles and interface guidelines, and proficiency with code versioning tools such as Git.
Skills related to Android, and can serve as a foundation for learning or mastering it, include a basic understanding of databases, particularly SQLite which is a common system used in storing app data in Android. Knowledge of XML is also important as it is needed for designing UI layouts in Android apps. Familiarity with the principles of User Interface (UI) and User Experience (UX) design is useful because creating an effective visual interface is a key part of Android app development. Finally, knowledge of general computing principles and exposure to another programming language, especially Object-Oriented Programming (OOP), will make the process of learning Android easier.
Being able to design and build applications for Android opens up many opportunities as it presents a key opportunity to work on innovative projects, for small businesses to large enterprises, in a rapidly growing field.
