I have an app in the Google Play store. When I create a new version of it how do I notify those who have downloaded the original app that an update is available?
Also, my phone is set to auto update so I get a notification when a new version of an app on my phone has been updated. How can I do that for users that have their phones set to auto update?

Android takes care of that. After you upload the apk file of the new version to Play Store, the store shows a notification to your users automatically. It may not happen instantly but will in a few hours. And if the user has enabled auto update, that will happen too.
