title: The method getLong(String, long) in the type SharedPreferences is not applicable for the arguments (String)
body: <p>I'm getting an error message stating "The method getLong(String, long) in the type SharedPreferences is not applicable for the arguments (String)" on the line (all the way at the end of my code):</p>
  
  <pre><code> long oldTime = pref.getLong("smstimestamp");
  </code></pre>
  
  <p>However I'm not sure how this can be resolved. </p>
  
  <p>Any suggestions?</p>
