APKtiedostojen

APKtiedostojen refers to files with the .apk file extension, which are used for the distribution and installation of Android applications. APK stands for Android Package Kit. These files are essentially archives, similar to ZIP files, containing all the necessary components for an Android app to run on a device. This includes the app's code, resources such as images and layouts, assets, and a manifest file that describes the app's fundamental characteristics and permissions.

Users typically encounter APK files when downloading apps from sources other than the official Google Play Store. While the Play Store automatically handles the download and installation process, installing an APK file manually requires enabling "unknown sources" in the device's security settings, which should be done with caution due to potential security risks. Developers use APK files to distribute their applications to testers or to users who prefer direct installation. The structure of an APK file allows for easy deployment and management of Android applications.
