title: Opening Firebase Dynamic Link with android app without FirebaseDynamicLinks
body: <p>I have an application at the Google Play and there are already a few hundred of users.</p>
  <p>Now, I'm working on an update that will allow users to share user-to-user content via <code>Firebase Dynamic Links</code>.</p>
  <p>In order to do so, I created a subdomain and all the required things and I added this code:</p>
  <pre><code>FirebaseDynamicLinks.getInstance()
                  .getDynamicLink( getIntent() )
                  .addOnSuccessListener( this, pendingDynamicLinkData -&gt; {
                      Uri deepLink = null;
                      if (pendingDynamicLinkData != null) {
                          deepLink = pendingDynamicLinkData.getLink();
                          String bookID = deepLink.getQueryParameter( &quot;id&quot; );
                          if (bookID != null) {
                              startBookDetailActivity( bookID );
                          }
                      }
                  } )
                  .addOnFailureListener( this, e -&gt; {
                          }
                  );
  </code></pre>
  <p>However, the users who already have the app installed on their phone don't have this piece of code in their application which means that if they click on the dynamic link it won't do the job.</p>
  <p>Is there any other way I can handle the dynamic link for the period until all users get the latest version?</p>
  <p>Thank you</p>
