AsyncTask has nothing to do with pending intents or activities. It's
just a utility class.

Check your logcat more carefully:

Assuming that com.mobisys is your application, look in
FBQueryAsync.java, line 50.

Are you somehow calling Facebook classes with a NULL pointer?

Are you using AsyncTask from a widget's onReceive?
