while u write R  you are referring to the R java class created by eclipse  use getResources   getString   and pass the id of the resource from which you are trying to read inside the getString   method   Example   String   yourStringArray   getResources   getStringArray R array Your array

Update   You can use getString R string some string id  in both Activity or Fragment  You can use Context getString R string some string id  where you don t have direct access to getString   method  Like Dialog    Problem is where you don t have Context access  like a method in your Util class   Assume below method without Context   public void someMethod                   can t use getResource   or getString   without Context      Now you will pass Context as a parameter in this method and use getString     public void someMethod Context context               context getString R string some id       What i do is   public void someMethod                App getRes   getString R string some id      What  It is very simple to use anywhere in your app   So here is a Bonus unique solution by which you can access resources from anywhere like Util class    import android app Application  import android content res Resources   public class App extends Application       private static App mInstance      private static Resources res         Override     public void onCreate             super onCreate            mInstance   this          res   getResources               public static App getInstance             return mInstance             public static Resources getResourses             return res             Add name field to your manifest xml  lt application tag    lt application         android name   App                       gt                   lt  application gt    Now you are good to go
