Android: Allow Installation from Unknown Sources

Android protects users from inadvertent downloading and installing apps from locations other than the Google Play store. Even if you wanted to add our apps, they will be blocked. It blocks these installs until the user opts into/enables “Unknown sources” in Settings > Security on their device.

To install apps that you downloaded from somewhere besides the Google app store or the company that made your phone, you need to allow installation from “unknown sources“.
