How Facebook tracks you on Android [video]
We're spoiled in the desktop browser by being able to clear history, cookies, local storage etc, or use a private browser session. There's also the importance of the  "same origin policy".<p>The Android platform API should simply never allow apps to obtain global system identifiers (serial numbers, "advertising IDs", MACs, Wifi network info, EMEIs etc) in the first place. Perhaps even going as far as not providing a shared filesystem.<p>Mobile apps, despite platform API permission, and having some ability to protect their own data, are a lot closer to desktop programs than web apps in many regards.
