如何使用Play安装引荐来源网址库将引荐来源网址从Play商店获取到应用程序？

Question

我想从我的应用内的Google Play网址获取引荐来源网址查询参数。

https://play.google.com/store/apps/details?id=<apppid>&referrer=myReferrerValue

我写了这个

InstallReferrerClient referrerClient;

referrerClient = InstallReferrerClient.newBuilder(this).build();
referrerClient.startConnection(new InstallReferrerStateListener() {
    @Override
    public void onInstallReferrerSetupFinished(int responseCode) {
        switch (responseCode) {
            case InstallReferrerClient.InstallReferrerResponse.OK:
                Log.d("InstallReferrerResponse","Connection established");

                ReferrerDetails response = null;
                try {
                    response = referrerClient.getInstallReferrer();
                    String referrerUrl = response.getInstallReferrer();

                    Log.d("InstallReferrerResponse",referrerUrl);
                } catch (RemoteException e) {
                    e.printStackTrace();
                }

                break;
            case InstallReferrerClient.InstallReferrerResponse.FEATURE_NOT_SUPPORTED:
                Log.d("InstallReferrerResponse","API not available on the current Play Store app");
                break;
            case InstallReferrerClient.InstallReferrerResponse.SERVICE_UNAVAILABLE:
                Log.d("InstallReferrerResponse","Connection couldn't be established");
                break;
        }
    }

    @Override
    public void onInstallReferrerServiceDisconnected() {
    }
});

但是我只得到utm_source=google-play&utm_medium=organic，没有得到Referrer = myReferrerValue。

如何获取Referrer = myReferrerValue？
