Jetpack
Jetpack is a collection of helpful tools that make Android app development easier and faster. Think of it like a toolkit that Google provides to app developers. Instead of building common features from scratch (like handling screen rotations, saving data, or showing images), developers can use these pre-made components. This saves time and helps create more stable apps. It's similar to buying pre-made furniture versus building everything from raw materials. When you see Jetpack mentioned in a resume, it usually means the candidate knows how to build Android apps using modern, recommended practices.
