Question

I am having difficulty understanding what a “static” method and “static” variable is and it is causing me problems with my code. Here is the code I am having difficulty with:

    public class Document{
      public void NewBlank(){
           Resources.openRawResource(R.raw.blank);
           }
       }

Why do I get the error “Cannot make a static reference to the non-static method Resource.openRawResource(int) from the type Resources”? Why can’t I reference a non-static method?

Answer 1

openRawResources is not a static method, it needs to be invoked in an object, not a type. In order to get an instance of Resources you could call getResources in an activity. Then the resulting code would be

Resources resources = myactivity.getResources();
resources.openRawResource(R.raw.blank);

A static method/variable is one that belongs to the class type, and not to the instances/objects of such type.
