title: Get right part of string in Android app
body: <p>Ok, I am trying to get the right three characters of a string in an Android app I'm writing.</p>
  
  <p>Based on the research I've done in the SDK and online I should be able to use something like the following to do it.</p>
  
  <pre><code>millisecondsD = millisecondsD.substring(millisecondsD.length() -3, millisecondsD.length());
  </code></pre>
  
  <p>However, I get a force close whenever I try to use to use the code above.  Am I just missing something super simple?</p>
