Android Package Kit (APK)

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—like code, resources, and assets—needed for an app to run. When you download an app from the Google Play Store or other sources, you're essentially downloading an APK file. The device then unpacks and installs it to make the app functional. APKs enable efficient app distribution, updates, and security, ensuring that apps can be easily installed and managed on Android smartphones and tablets.
