title: Constants in Android xml file
body: <p>I have some code like this in my Android settings xml file (res/xml/settings.xml):</p>
  
  <pre><code>    &lt;EditTextPreference
              android:title="@string/settings_date_format"
              android:summary="@string/settings_date_format_summary"
              android:key="settingsDateFormat"
              android:defaultValue="@string/config_settings_date_format_default_value" /&gt;
  </code></pre>
  
  <p>And a string like this:</p>
  
  <pre><code>&lt;string name="config_settings_date_format_default_value"&gt;dd MMM yyyy, HH:mm&lt;/string&gt;
  </code></pre>
  
  <p>As you can see, I'm setting the default value to a string. However, I'd like to have these default values stored somewhere else as it doesn't make sense to put them in res/values/strings.xml</p>
  
  <p>Is it possible for me to put them in a new file called "config.xml" for example?</p>
