With Android 2.3, users will have not only a slew of new features (I can't wait!), but also a fix to a security issue present in the previous versions of Android: TapJacking. TapJacking occurs when a malicious application displays a fake user interface that you can interact with, but actually secretly passes interaction events, such as finger taps, to a hidden user interface behind it. Using this technique, a devious developer could potentially trick a user into making purchases, clicking on ads, installing applications, or even wiping all of the data from the phone.
