Do i have to close a cursor when using
startManagingCursor(cursor); //I know its deprecated
and
cursor.registerContentObserver(..
if so, where to close it?
解決
If using startManagingCursor
you do not need to close the cursor, Activity will take care of that for you.
But if you have called registerContentObserver
, you need to call unregisterContentObserver
. Usually you call registerContentObserver in OnResume and unregisterContentObserver in OnPause, But it can change depending upon what kind of operations you are performing in ContentObserver
.
