You will notice a few changes:

• We now get the _ID column out of our content provider, in addition
  to the name, and we adjust the code that fills in the name widget's

text to match.

• We create an activity PendingIntent for the DetailForm activity.
  However, we add in the ID_EXTRA "extra", so DetailForm knows which

restaurant to show. And, since we are changing extras on an

otherwise-unchanging Intent, we need to add the

FLAG_UPDATE_CURRENT flag in our getActivity() call, so the new extra

takes effect
