APK

APK stands for Android Package Kit. It is the file format used by the Android operating system for distributing and installing applications. Much like a software installer on a computer, an APK file contains all the necessary components for an app to run on an Android device, including the code, resources, and manifest file that describes the app's features. Users can download APKs from the Google Play Store or other sources, allowing them to install applications directly, bypassing the store if needed. This flexibility enables developers and users to share and install apps easily.
