Google is announcing the "Android Privacy Sandbox" today, a move the company says will be "a multi-year initiative" to introduce "more private advertising solutions" into Android. After Apple made tracking opt-in in iOS 14, Android wants to be seen as matching its main rival. Today's announcement is in addition to existing ad systems, not a replacement for them, so this will probably be even less effective than the "Privacy Sandbox" for Chrome.

Apple's tracking changes blew up the advertising industry and are already costing ad-based companies like Facebook $10 billion in revenue for the year. Google, the world's largest ad company, doesn't seem to want to do that on Android.
