An APK (Android Package Kit) is the file format used for distributing and installing applications on Android devices. It contains all the necessary elements of an app, including the code, resources, assets, and manifest file. APKs are similar to executable files (.exe) on Windows and are used to install apps manually outside the Google Play Store. Users can download APK files from various sources, but caution is needed to avoid malware. Developers use APKs for testing before publishing their apps. To install an APK, users must enable "Unknown Sources" in their device settings. APKs allow early access to apps and modified versions.
