Hello All, i'm updating one of my apps, i decided to add a preference activity to let users set some default settings, the app works fine the first time, when i launch the preference activity and select an option from one list and another option from a second list, then let's say i exit the application and then i re-open it the second time i launch the preference activity the app crashes with this error

Force finishing activity com.genesisitdev.thepiratebay/anywheresoftware.b4a.objects.preferenceactivity
Force finishing activity com.genesisitdev.thepiratebay/.main
Activity pause timeout for HistoryRecord{40acd8d8 com.genesisitdev.thepiratebay/anywheresoftware.b4a.objects.preferenceactivity}
Any ideas as to why this would be, this is the first time i use this library, and it is possible i may be missing something but i can't pin point exactly what, I have added this line to my manifest file
AddApplicationText(<activity android:name="anywheresoftware.b4a.objects.preferenceactivity"/>)
Any help will be appreciated.
Thanks,
Walter
