title: Preference ringtone default value
body: <p>I have this in my preferences.xml</p>
  
  <pre><code>        &lt;RingtonePreference android:key="ringtone_uri"
              android:title="@string/preferences_select_ringtone"
              android:showDefault="true" android:srinlent="true"
              android:summary="@string/preferences_select_ringtone_summary" /&gt;
  </code></pre>
  
  <p>And every time when I first start fresh install of an app, the default value in silent :(, When I tap on the ringtone preference the dialog is opened with silent selected as default. I want by default "Default ringtone" to be selected. How can I do this

  <p>How can I set the default value to be "default ringtone" not silent, I do not know why is this silent as my default I do not set in any place in my code, the silent is the default from android system ...</p>
