Android Library that checks for updates on Google Play, GitHub, Amazon, F-Droid or your own server. This library notifies your apps' updates by showing a Material dialog, Snackbar or notification. Check out the wiki. By default, the basic usage will show a default dialog when a new version is found on the Play Store (otherwise nothing will be shown). By calling the .start() method, the library will work in background. You can cancel it at any time by calling .stop(). Other customizations are explained below.
