if the info has to remain you have to use a predefined class to store your information, as String, Boolean, Integer... or Vector, Hashtable etc.
If you put an own class into the store that implements Persistable the store will get deleted if you remove the application.

Thanks simon_hain for your reply. But in APIDocs: "Every object that can persist between handheld resets must implement persistable". If my app not implement Persistable and use predefined class to store my app data, are you sure my app data is maintain when restart device. Please, show me more detail If you can. Thanks very much !

some classes already implement persistable. the ones i mentioned for example. see the API for details.
