Background

The ability to identify users is important for advertising, analytics and other purposes. Android developers typically rely on the Android Device ID or Telephony IDs such as the International Mobile Equipment Identity (IMEI) to uniquely identify users, but these approaches also introduce privacy concerns. Android 4.4 Kitkat introduces a new anonymous identifier for advertising purposes. Referred to as Advertising ID, it provides a user-resettable identifier that helps protect the user’s personal identity. Google defines Advertising ID as follows:

“The advertising ID is a user-specific, unique, resettable ID for advertising, provided by Google Play services. It gives users better controls and provides developers with a simple, standard system to continue to monetize your apps. It is an anonymous identifier for advertising purposes and enables users to reset their identifier or opt out of interest-based ads within Google Play apps. The advertising ID is accessible through a straightforward API that you can implement in your apps.”

Advertising ID is supported in Google Play services 4.0+, and follows the format of UUID, for example: “96bd03b6-defc-4203-83d3-dc1c730801f7“.

Summary

Developers have a number of options to generate unique user identifiers. These include Telephony identifiers such as IMEI or the Android Device ID. Starting with Android 4.4, developers can use the Advertising ID that provides a user-specific, unique, and resettable ID for advertising, as provided by Google Play services.
