Short Dynamic link error com.google.android.gms.common.api.ApiException: 8:

Firebase team was able to reproduce the issue and has already reported this to their team.

Currently, there are two workarounds for this issue:

• Use the Dynamic Link version 16.0.1 to be able to generate a short Dynamic Link: implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-dynamic-links:16.0.1'

• Stick in using version 16.1.1, create a long link first then try to shorten the long Dynamic Link using this guide.

Use my solution to build your short link and avoid downgrading firebase.

           String builtLink = new LinkBuilder().setDomain("example.page.link")
           .setLink("your link goes here")
           .setSd(socialTagDesc)
           .setSt(socialTagTitle)
           .setSi("social image link here")
           .setApn("android app pkg")
           .setAmv("android min version")
           .setIbi("ios app pkg")
           .setImv("ios app min version")
           .setIsi("iosid number").build();

    DynamicLink.Builder builder =  FirebaseDynamicLinks.getInstance().createDynamicLink()
            .setLongLink(Uri.parse(builtLink));

    builder.buildShortDynamicLink()
            .addOnSuccessListener(listener)
            .addOnFailureListener(failureListener);
