.APK is Android Package File
An APK file is an app created for Android, Google's mobile operating system. Some apps come pre-installed on Android devices, while other apps can be downloaded from Google Play. Apps downloaded from Google Play are automatically installed on your device, while those downloaded from other sources must be installed manually.
Typically, users never see APK files because Android handles app installation in the background via Google Play or another app distribution platform. However, there are many websites that offer direct APK file download for Android users who want to install apps manually themselves. In this case, you should be careful that you trust the source of the APK file, because malware can be distributed in APK files, just as it can in the case of Windows and .EXE files.
