You don’t need to page your lists. The Android ListView is very
efficient at displaying long lists (recycling views, fast scrolling,
etc), assuming you are showing data derived from a database (there are
other examples if you are dynamically downloading your data)

I have Call Log Widget on the Android Market:
http://blog.zedray.com/call-log-widget/
The core of this Widget is an AppWidgetProvider which registers a

is updated every time a call (incoming, outgoing, missed) is
recorded.
Ah, BroadcastReceiver - ACTION_PHONE_STATE_CHANGED. That's the sort
of life-cycle I was looking for. :-D

Use a MatrixCursor instead of a CrossProcessCursor.
This will allow you to send custom data in a Cursor object over a
ContentProvider, and works across the process boundary.
Example code:

So correct me if I am wrong, but the only Cursors that can be sent
across a process boundary are the ones created by SQLite?

Can you comment on whether the community will see another Android SDK

I know the UI is supposed to be a *big surprise*, but there are so
many other APIs that us regular developers would love to give feedback
on.
OK, thanks for giving feedback.
Perhaps someone else from Google (who is more in the know) could throw
