The app has 2 columns of 10 EditTexts each, a Save Button, a Export Data button and a Import Data button. When I press Save Button I want like my data entered in the EditText fields to be saved with Shared Preferences. When i press Export Data Button i want like the app to take the values stored in the Saved Preferences and export them in a xml or cvs file on the mobile storage as a back up solution. If I reinstall the app, when press Import Data i want to be able to browse the xml or cvs file from the storage and populate with the values the 2 columns of 10 edit texts each.
