Android 4.x and Dropbox - does not authenticate
<p>I've implemented a Dropbox interface in my Android app exactly as shown in the example
on the dropbox dev guide - <a href="https://www.dropbox.com/developers/start/setup#android" rel="nofollow">https://www.dropbox.com/developers/start/setup#android</a></p>

<p>It works perfectly on my Android 2.3.5 device, and works fine on my 4.x Emulator.  However, in testing on real devices, it fails on 4.x devices with a "Not properly authenticated" error.
Two separate devices running 4.x have failed in the same way. </p>

<p>I realize this is a bit of a stretch to ask a question with out all the tech details, but the plain truth is I don't have them. The two users I was able to convince to help test on their real devices are a) remote and b) completely non-technical, so I have no Logcat data or stacktrace or anything else that might help.  I was simply hoping someone else has run into
this and might have an answer.  Failing that, anyone have a 4.x device they would be willing to run an app on and provide some logcat data?</p>
