Remarks

Performs the query that created the cursor again, refreshing its contents. This may be done at any time, including after a call to #deactivate.

Since this method could execute a query on the database and potentially take a while, it could cause ANR if it is called on Main (UI) thread. A warning is printed if this method is being executed on Main thread.

This member is deprecated. Don't use this. Just request a new cursor, so you can do this asynchronously and update your list view once the new cursor comes back.
