title: The method getResources() and context is undefined for the type
body: <p>I use the <code>getString()</code> to become String from string.xml.
  In my class (non-activity) does not work:</p>
  
  <ul>
  <li>context.getResources().getString()</li>
  <li>getResources().getString()</li>
  <li>context.getResources().getString()</li>
  </ul>
  
  <p>How do I get the String to this class?</p>
  
  <pre><code>public class myClass{
       public String[] myInfo(String ID) {
          String myString = getRessources().getString(R.string.myString);
       };
  }
  </code></pre>
