I would like to be able to use the time-limited trial version of my application, but I'm not sure how I can reliably determine if the user tried to reinstall the application after the expiration date.
I could save the start date of the installation to a repository that does not get deleted when uninstalling, but this does not seem to be the ideal method. Does this app support Google Play Application Licensing or is there another acceptable way to do this?
