问题 I have a sync adapter that works fine. It does not need internet connection because it needs to sync the addressbook with another local storage (my application). When the Wifi is turned off and the device does not have any internet connection Android disables the sync in the Account & Synch settings activity.

问题 My Java application needs to hold cursor to Oracle DB for some time. During it other DB statements have to be made. Does this require separate DB connections or same (cursor's one) can be used?
