We are trying to develop a widget that may need to save considerable amounts of data, and I was wondering if the S60's preference for key method, had any type of limitations.
We're developing quite a lot of widgets, and time is an issue, that's why we're considering the possibility of using the Widget's setPreferenceForKey() just as it was a small database.
But before doing that we need to know about any known limitations for these preferences, so any feedback would be really appreciated.
- Limited number of keys ?
- Limited length for a key's value?
- System/Widget performance problems with large amount of keys?
