title: How to set a DefaultSharedPreferences value?
body: <p>I have a preferences activity with a checkbox "Enable Service".</p>
  
  <p>I read the value like this :</p>
  
  <pre><code>SharedPreferences prefs = 
  PreferenceManager.getDefaultSharedPreferences(con);
  ServiceEnabled_Pref = prefs.getBoolean("EnableService", true);
  </code></pre>
  
  <p>ok, but how can I set this Preference ?</p>
  
  <p>this is not a CustomShared Preference, It is a DefaultShared Preferences and it seems that there is not a method putBoolean for DefaultSharedPreferences.</p>
  
  <p>I need this, cause I have a Widget with a button that needs to set this value to true/false </p>
