APKs (Android Package) are a file format that is used to distribute Android Applications.
Android has the advantage that you can create your own APKs and install them on devices.
You do need to enable the ability to install APKs from unknown sources to do this.
This does have security risks and should only really be done on development devices.
The steps can change slightly depending on the device manufacturer and version of Android, but it’s usually in settings.
Often when you try to install an APK it will ask you if you want to change permissions. Android 12 allows you to set this as you install apps.
