Hi jfernandez and all. I've had the same problem for half a year. My device is Galaxy Nexus SC-04D ver4.0.4. I've not solved this problem yet, in spite of half a year researches. I gradually be sure that this is a bug of unregisterAppConfig(). Here is a report about this problem. Google android group http://code.google.com/p/android/issues/detail?id=26704&can=1&q=hdp&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars
I think this is a only way to report the bug to Android API developers, because developer.android.com provides this forum as a Support. So, I want you to add a star or comment to this issue, if you have the same problem. And wish to be debug.
