Okay, sure, if you are letting the user open and close databases then you
could have an arbitrary number open (if you are actually letting the user do
that). But then... you also already have the answer for when to close the

For the vast, vast majority of Android applications, there will just be a
couple databases the app is dealing with, which a reasonable implementation
would just leave open.
