Database.isOpen()

[cherrydev]

It would be great if the Database interface exposed the .isOpen() method of the delegate. I'm dealing with an app that uses AccountManager and has separate databases for each user. When an account is deleted, a callback deletes the underlying database, but if the app is still running, when my Activity resumes it needs to check if the database is still open. I can do it by getting the raw database and then casting it (to one of two implementation classes, depending on if it's encrypted or not) but it seems like adding .isOpen() to the interface should be straightforward.
I'd be happy to submit a pull request for it if the idea is approved. Thanks.

@cherrydev The built-in StandardDatabase and EncryptedDatabase always return a SQLiteDatabase for Database#getRawDatabase. So you should be safe to cast to SQLiteDatabase and call isOpen() on it. -ut

There are two SQLiteDatabase classes in two different packages, one for the standard, one for the encrypted. There is no common interface or subclass for these two SQLiteDatabase classes. Therefore a single call to isOpen() requires code for two instanceof expressions and two casts. The Database interface has a close() method on it. Why not isOpen()?

Sorry, I missed the different package for SQLiteDatabase. Suggested a change. Thanks! -ut
