An APK (Android Package Kit) is the file format used by Android to distribute and install apps. It contains all the elements an app needs to install correctly on a device, including the app’s code, resources, assets, certificates, and manifest file. APK files are similar to .exe files on Windows. Users can download APKs from the Google Play Store or third-party sources. Installing APKs manually allows early access to updates or apps not available in certain regions. However, caution is advised when installing from unknown sources to avoid malware.
