Hi all, Now I have 2 activities that would simultaneously access one data/ settings. However, two kind of solution can be applied after I study from the Android Developer's Guild.
One is ContentProvider, The discription in guild is as: "Content providers store and retrieve data and make it accessible to all applications. They're the only way to share data across applications; there's no common storage area that all Android packages can access." and another is SharedPreferences, "To use preferences that are shared across multiple application components (activities, receivers, services, providers), you can use the underlying Context.getSharedPreferences() method to retrieve a preferences object stored under a specific name." What is the differenet between these 2 ? Thanks a lot! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
