title: String resource returns a number?
body: <p>In my android project I have a string resource (string.xml) in the res/ folder.</p>
  
  <p>in that string.xml I have created several strings, like:</p>
  
  <pre><code>&lt;string name="my_server"&gt;http://12.34.56.78&lt;/string&gt;
  &lt;string name="my_port"&gt;1234&lt;/string&gt;
  </code></pre>
  
  <p>then I use in the code:</p>
  
  <pre><code>String url = R.strings.my_server + ":" + R.strings.my_port;
  System.out.println("My server and port is: " + url);
  </code></pre>
  
  <p>but my output is:</p>
  
  <blockquote>
    <p>My server and port is : 2131099700:2131099702</p>
  </blockquote>
  
  <p>Where is my string? That seem kind a adress of that string?</p>
