PendingDynamicLinkData имеет значение null

Question

Я разрабатываю приложение, которое может делиться и получать вознаграждение, поэтому я использую концепцию динамической ссылки, чтобы хранить информацию приглашающего в этой ссылке, а затем получать вознаграждение.но PendingDynamicLinkData возвращает нулевое значение при установке приложения после упомянутой ссылки.

MainActivity

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();

    googleSignInClient = GoogleSignIn.getClient(this, gso);

    checkInvitations();
}

void checkInvitations() {

    FirebaseDynamicLinks.getInstance().getDynamicLink(getIntent())
            .addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() {
                @Override
                public void onSuccess(PendingDynamicLinkData data) {
                    if (data == null) {
                        Diagnostics.e(this, "No data").append(activity);
                        return;
                    }

                    // Get the deep link
                    Uri deepLink = data.getLink();

Answer 1

Скорее всего, вы хотите проверить намерение при запуске - в данный момент похоже, что вы запускаете InfoActivity, а динамические ссылки, когда приложение установлено, переходят на InvitationActivity, но ваш код проверки ссылокв MainActivity.
