[android-developers] Re: Contacts-based app force-closing on Droid, unable to repro

Hey Eric,

When I was working on a Droid I found that fields were null
unexpectedly when I queried for a specific MIMETYPE. The display name
for a contact is not null with a GroupMembership MIMETYPE query but
there is no data in the phone number fields. My guess is that the
Phone.Number MIMETYPE might not have a display name column. Like me,
you may need two queries. One with a MIMETYPE that has display name
and another to fetch the numbers where selection is based on the
contact_id or raw_contact id collected in the first query.

Here is a question for you... How do you put contact data into the
Emulator? Unfortunately for me, although contacts can be loaded, the
Emulator data cannot be grouped. This means I am not able to use the
Emulator at all to test my code since I query for the
GroupMembership.CONTENT_ITEM_TYPE. If you or anyone has a suggestion,
great, my access to the Droid is limited and I really want to put out
a new feature on Alarmoid.

Boas Festas!
Beth
