AdId may be phased out in interest of Topics API and Fledge in Android Tiramisu Privacy Sandbox changing the Landscape of Targeted Ads in Android

[n-aggarwal]

As previously discussed, google is introducing the Privacy Sandbox. It turns out that google plans to phase out Android ID and instead use Topics API to "help preserve users' privacy" over the next 2 years. This would mean that our AdId solutions would fail to work in the long run, so we may need to rethink our implementation approaches.

"Our goal with the Privacy Sandbox on Android is to develop effective and privacy enhancing advertising solutions, where users know their privacy is protected, and developers and businesses have the tools to succeed on mobile. While we design, build and test these new solutions, we plan to support existing ads platform features—including advertising ID—for at least two years, and will provide substantial notice ahead of any future changes."

Android ID is a different thing compared to AdID though!
