Saving an entire Bundle to SharedPreferences

Question

Assuming a method of mine was passed a Bundle already filled with data to be saved, is there a way to save it to SharedPreferences without taking it apart to ints, floats, Strings, etc.?

I prefer the convenience of writing/committing it all in "one fell swoop", so if this isn't possible using SharedPreferences, what other persistent storage approach would you recommend?

Answer 1

SharedPreferences are serialized to XML, which is why you can only use simple types. You'll either have to do your own conversion of the bundle to individual SharePreferences properties or serialize the bundle some other way to disk.
