I just ran into this and thought I would post this for anyone else who might be struggling with the same problem.
In creating preferences, I had the following code in res/xml to define my preference activity: <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/ android"> <CheckboxPreference android:key="App_Start_Notification" android:title="Notify When AppSwipe Starts" /> <CheckboxPreference android:key="Boot_Notification" android:title="Notify On Boot" /> </PreferenceScreen> ADT did not complain about this (and is usually pretty good about catching errors) so I thought everything was fine. However, when I went to access my preference activity I got a crash and logcat gave a ClassNotFoundException. Turns out it was a simple change: Checkbox should have been CheckBox! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
