Android programmatically update application when a new version is available

Question

Within my application, I want to check if there is any updated version of my application is in the app store. If there is any, then have to inform the user through an alert

Answer 1

Google Play already does this. When you upload a new version of your app, it will either send an alert directly to your users' devices or download the upgrade automatically if the user has this option turned on in the Google Play app.
