Regarding your first question: strings.xml file is used for storing string resources, especially for the sake of resolving the localization issues. You can store multiple strings.xml files inside your project in different folders depending on the localization. This makes translating your application to a different language easier: you just create another strings.xml file, translate all the strings and put it inside the corresponding folder. Hope this helps.
