interfere with game play. One Android user we know recently downloaded some live wallpaper from the Google Play Store. This might have been one of the worst offenders as ads crudely disguised as notifications started popping up. Another friend, (we do have more than one, you know!) recently installed the free version of Alec Baldwin's favorite airplane time killer Words With Friends, and found an ad displayed after every turn.
The new Ad Content policy from Google requests that each ad make it clear which app it "belongs to". Ads should not add bookmarks, shortcuts, icons or change default settings without the user's knowledge and consent. The user should be able to reverse the changes. More importantly, Google now says ads cannot ape notifications or warnings. Hopefully this means that Android owners can install live wallpaper without fear of getting bombarded with notification-style ads.
