You can approach in this way

in the first time user install and start the application, you should store the current version as last_vertion_of_app in the shared preferences. then use a alarm Manager +broadcast receiver+service to check the manifest app version with shared preference stored version if both are different(not equal) that means some update happen. then you can do the thing what you want to happen if updated=true in the save service even without application starts.
