Ah, ok, I must have misunderstood this line in your log (taking it to
mean the return from getView).
>> 09-24 16:02:20.688: DEBUG/MGCM(357): About to return view <<
Anyway, you could assign the adapter right away, and just make it return
0 from getView if there is no data yet.

Thank you for your response.
I tried what you suggested. The getView code snippet from the base
adapter is here. It definitely would return a non-null value, but the
error above appears to happen before this gets a chance to be called.
(The debug statement didn't get executed.)
public View getView(int position, View convertView, ViewGroup parent) {
FeedListItem temp = (FeedListItem) mBlogFeed.getListFeed().get(
position);
convertView = mInflater.inflate(R.layout.rowlistviewtitledescr,
null);
TextView itemTitle = (TextView) convertView
.findViewById(R.id.textviewListViewTitle);
TextView itemDescr = (TextView) convertView
.findViewById(R.id.textviewListViewDescr);
itemTitle.setText(temp.getTitle());
Date pub = (temp.getPubDate());
Date upd = (temp.getUpdDate());
String datetext;
if (pub.getYear() == 0) {
datetext = "Unknown";
}
else {
datetext = mDateFormat.format(pub);
if (upd.getYear() != 0 && upd.compareTo(pub) != 0) {
datetext += " (Upd: " + mDateFormat.format(upd) + ")";
}
}
itemDescr.setText(datetext);
*if (Constants.DEBUGGING) {*
*Log.d(Constants.LOG_TAG, "convertView is Null: "*
*+ Boolean.toString(convertView == null));*
*}*
return convertView;
}
In fact, from what I can tell, the issue is occurring during the
layout of the screen widgets. I don't assign the adapter to the
listview until after the data is retrieved. The error is occurring
before that has happened - you can see on the onPostExecute above
where the adapter gets assigned and the debug statements didn't get
logged. And, of course, it works quite well when run on devices with
an SDK >= 2.2 (even tablets). This is the vexing part.
I'm starting to follow your lead and diving into the source code to
see if I can find some sort of clue.
Thank you again for your suggestion.
Best Regards,
Eric
