How can I save a GridView with Vector list in android? I 'm developing a launcher and I want the shortcuts to be saved after onDestroy or any crash.
Not sure what you exactly mean, but why not save data using SharedPreferences at some stage while the application is running? or when user makes some changes.
Here is an example of how to use sharedpreferences. How to use SharedPreferences in Android to store, fetch and edit values
