How Google Play Campaign Measurement works
Google Play Store Campaign Measurement relies on the use of Campaign Parameters to pass campaign and traffic source information into your app at the time that it is downloaded from the Google Play Store.
The following is an end-to-end description of how Google Play Campaign Measurement works:
A user clicks on a link, from an ad, website, or app, that takes them to your app's Google Play Store page. The link is tagged with Campaign Parameters. After the user downloads and installs your app, the Google Play Store will broadcast an INSTALL_REFERRER intent on the device that includes those same campaign parameters. Your app will then respond to that intent, using the BroadcastReceiver object provided below, reading the campaign parameters and using them to update the Google Analytics campaign information.
