Android Package Kit

An Android Package Kit (APK) is the file format used to distribute and install applications on Android devices. Think of it as a container that holds all the necessary components—such as code, resources, assets, and metadata—needed for an app to run. When you download and install an app, your device opens this APK file to set up the app and make it ready for use. Essentially, the APK is the digital package that carries an Android app from developers to your device, ensuring everything needed is included for proper installation and operation.
