"Do you mean a new connection to the database for each activity? " Yes. How many activities do you expect to have active (i.e. in a state between onCreate and onDestroy)?
If this number is very large, then a singleton that manages such a connection can be the best thing to do. But if this number is relatively small, just keep it easy and open a connection in each onCreate and close it in onDestroy. Don't worry about onDestroy not being called. If onDestroy is not called, your process will be killed, closing all connections automatically.
