title: How do we know which graph api version we are using from the SDK
body: <p>Once in a while, we get this email from Facebook about a graph API is about to be deprecated. </p>
  
  <p>We are using both the iOS SDK and Android SDK in our apps. </p>
  
  <ul>
  <li><a href="https://developers.facebook.com/docs/ios/graph" rel="noreferrer">https://developers.facebook.com/docs/ios/graph</a></li>
  <li><a href="https://developers.facebook.com/docs/android" rel="noreferrer">https://developers.facebook.com/docs/android</a></li>
  </ul>
  
  <p>I know the SDK use the graph API internally, but I find it tricky to tell which version of the graph API we are using from the SDK.</p>
  
  <p>Is there a way to tell which graph API version we are using given the SDK version number? </p>
