The Overflow Blog. Android operating system uses its own type of installation format, as like windows softwares have. When you download an app from Google play store, it is downloaded and installed in APK format. You will not see the file directly when you download it from play store. At times you may want to download APK files from other sources directly.

Advantages: You can download any version of the app directly from third-party websites. They may have app archives of most versions and you can download the one you may need. Downloading is instant unlike play store, no need to wait for the verifcation process etc. So you can uninstall and re-install as many as times without needing to download.

Disadvantages: Downloading apps from third-party sources usually are not verified by Google. So can be harmful to your phone. APK files can have viruses that will steal data from your phone or corrupt your phone. Your apps will not be updated automatically as Google play store usually don't have access to it. But we strongly recommend not to download from any third-party sources.
