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

Question

I am trying to get Firebase dynamic links to work in my app.

I have a function with the following

    //long
    String link = "http://www.blessd.mobi";
    DynamicLink m = FirebaseDynamicLinks.getInstance().createDynamicLink()
            .setLink(Uri.parse(link))
            .setDynamicLinkDomain("blessd.page.link")
            .setAndroidParameters(
                    new DynamicLink.AndroidParameters.Builder("mobi.blessd")
                            .build())
            .buildDynamicLink();
    Uri t = m.getUri();
    String ll = t.toString();
    Log.d(TAG + " long link:", ll);

    //short
    Task<ShortDynamicLink> shortLinkTask = FirebaseDynamicLinks.getInstance().createDynamicLink()
            .setLink(Uri.parse("http://www.blessd.mobi"))
            .setDynamicLinkDomain("blessd.page.link")
            .setAndroidParameters(
                    new DynamicLink.AndroidParameters.Builder("mobi.blessd")
                            .build())
            .buildShortDynamicLink()
            .addOnCompleteListener(this, new OnCompleteListener<ShortDynamicLink>() {
                @Override
                public void onComplete(@NonNull Task<ShortDynamicLink> task) {
                    if (task.isSuccessful()) {
                        // Short link created
                        Uri shortLink = task.getResult().getShortLink();
                        Uri flowchartLink = task.getResult().getPreviewLink();
                        String sl = shortLink.toString();
                        String fcl = flowchartLink.toString();
                        Log.d(TAG + " short link:", sl);
                        Log.d(TAG + " flow chat link:", fcl);
                    } else {
                        // Error
                        // ...
                        Log.d(TAG + " short links:", "problem");
                        Exception exception = task.getException();
                        Log.e("TAG", "Short Dynamic link error", exception);
                    }
                }
            });

I successfully generate a long link. I have debugged the long link in debug mode in a web browser and there are no errors.

The short link however does not run and I receive the following error:

09-03 16:14:06.816 4551-4551/? E/TAG: Short Dynamic link error com.google.android.gms.common.api.ApiException: 8:

Thanks.

Answer 1

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);





 public class LinkBuilder
 {
    private String domain;
    private String link;
    private String apn;

        catch (Exception ex){
            Timber.e(ex);
        }

        return input;
    }


    public LinkBuilder setDomain(String domain) {
        this.domain = domain;
        return this;

    public LinkBuilder setLink(String link) {
        this.link = getURLEncode(link);
        return this;

        this.apn = apn;
