APK stands for Android Package Kit and is a file extension for Android Package files, which are used to distribute apps on Google’s Android OS. It’s similar to the.exe files used to instal apps on Windows OS. From the app’s resources and manifest to the app’s compiled application code, APK files contain all of an app’s data.
We normally download apps from the Play Store without even realising the word APK is in the title. Since Android handles the software installation process in the background, this is the case. There are numerous websites that have APK files for download if you know how to manually instal software.
However, you must always exercise caution when installing these files, as malware can easily be spread in APK files, just as it can in.exe files.
