title: PreferenceManager Trouble
body: <p>I have got my self into a problem. I have a PreferenceManager that keeps track of some preferences that have default values and can be set by the user at run time. The other day i was testing this and input a value that apparently is not handled by the way i have it set up. I want to load the default values that are set in the xml file so that my application will run again. Right now, it gets to the part where it is loading the value below</p>
  
  <pre><code>dR.sethRVMax(Integer.parseInt(prefs.getString("hRVMaxKey", "100")));
  </code></pre>
  
  <p><strong>And then it spits out this error</strong></p>

  <p>I would like to load the complete defaults from the xml instead of trying to load the last saved preference. I have tried the following and it is not working:</p>
  
  <pre><code>SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
  PreferenceManager.setDefaultValues(this, R.xml.settings, true);
  prefs.registerOnSharedPreferenceChangeListener(this);
  </code></pre>
  
  <p>If more information is needed please let me know.</p>
  
  <p>Thanks in advance!</p>
