SHORT ANSWER: Using query parameters instead of path variables you could use the getQueryParameter method from the Uri object returned by pendingDynamicLinkData.getLink()

---

What i've been doing is using query parameters instead of path variables.

Instead of sending http://www.myapp.com/offer/123, i'm sending something like http://www.myapp.com/?offer=123

To add parameters dynamically i'm just concatenating strings: "http://www.myapp.com/?offer=" + myValue

This URL is in turn a query parameter of the dynamic link created in firebase:

String url = "https://YourDynamicLinkIdentifier.app.goo.gl/?link=https://myapp.com?offer=" 
+ myOfferVar 
+ "&apn=com.your.apn"; // << Dont forget to change this too

And this resulting URL is the one i send to the url shortener.

Then in the callback onSuccess(PendingDynamicLinkData pendingDynamicLinkData) call getLink() of pendingDynamicLinkData as you're already doing.

Now that you have a Uri object, you can easily get the parameter by calling the method getQueryParameter("offer").

if (pendingDynamicLinkData != null) {
     deepLink = pendingDynamicLinkData.getLink();
     String offerKey = deepLink.getQueryParameter("offer");

NOTE: In case you still prefer to use the path variable, you could get the last segment of the Uri path. See How to obtain the last path segment of an uri
