Check if Firebase invite led to the Play Store

问题

When using Firebase invites and accessing the dynamic links at the startup of the app on Android, is there a way to know whether the user just installed the app thanks to the invite or whether it was already installed?

Many thanks,

Borja

It turns out that you can find this out using method AppInviteReferral.isOpenedFromPlayStore(result.getInvitationIntent()). In the activity that runs when you click on the invitation:

// Create an auto-managed GoogleApiClient with access to App Invites.
mGoogleApiClientInvite = new GoogleApiClient.Builder(this)
        .addApi(AppInvite.API)
        .enableAutoManage(this, this)
        .build();

// Check for App Invite invitations and launch deep-link activity if possible.
// Requires that an Activity is registered in AndroidManifest.xml to handle
// deep-link URLs.
boolean autoLaunchDeepLink = false;
AppInvite.AppInviteApi.getInvitation(mGoogleApiClientInvite, this, autoLaunchDeepLink)
        .setResultCallback(
                new ResultCallback<AppInviteInvitationResult>() {
                    @Override
                    public void onResult(AppInviteInvitationResult result) {
                        if (result.getStatus().isSuccess()) {
                            // Extract information from the intent
                            Intent intent = result.getInvitationIntent();
                            String invitationId = AppInviteReferral.getInvitationId(intent);
                            boolean alreadyUser = AppInviteReferral.isOpenedFromPlayStore(result.getInvitationIntent());
                            if (alreadyUser) {
                                // Do stuff...
                            } else {
                                // Do other stuff...
                            }
                        }
                    }
                });

Based on this Google product form post, the Firebase Dynamic Links library will only check for incoming deep links once per app lifetime, meaning you'd need to uninstall and reinstall the app for it to check again. This feeds into the behavior of the getInvitation() method, and it appears you can imply whether the app was previously installed based on the results of this method.

To me, this seems awfully confusing. At Branch.io we do it completely differently: your link data object will always contain an is_first_session boolean, which you can programmatically handle in any way you choose.
