如何在我的Android应用中获取Google点击ID（gclid）？

Question

我在android ads的Google adsense中有一个广告，我知道当用户点击广告时，google会创建带有有关用户信息的链接以进行跟踪。所以我想在其中获取该链接和gclid参数。我该怎么办？

我已经尝试使用Intent和Google Play安装引荐来源网址进行操作，但是Intent返回null，并且Google Play安装引荐来源网址返回空字符串，有时还返回FEATURE_NOT_SUPPORTED

这是我获取代码的意图：

        val intent = this.intent
        val uri = intent?.data
        urlFromIntent = uri.toString()

清单：

       <receiver android:name="com.google.android.gms.analytics.CampaignTrackingReceiver"
                  android:enabled="true"
                  android:exported="true">
            <intent-filter>
                <action android:name="com.android.vending.INSTALL_REFERRER" />
            </intent-filter>
        </receiver>
        <service android:name="com.google.android.gms.analytics.CampaignTrackingService"
                 android:enabled="true"
                 android:exported="false" />

我的Google Play安装引荐来源代码：

        mRefferClient = InstallReferrerClient.newBuilder(this).build()
        mRefferClient.startConnection(object : InstallReferrerStateListener {

            @SuppressLint("SwitchIntDef")
            override fun onInstallReferrerSetupFinished(responseCode: Int) {
                when (responseCode) {
                    InstallReferrerClient.InstallReferrerResponse.OK -> {
                        try {
                            if (BuildConfig.DEBUG) Log.d("InstallReferrerState", "OK")
                            var response = mRefferClient.installReferrer
                            urlFromReferClient = response.installReferrer
                            urlFromReferClient += ";" + response.referrerClickTimestampSeconds
                            urlFromReferClient += ";" + response.installBeginTimestampSeconds
                            mRefferClient.endConnection()
                        } catch (e: RemoteException) {
                            urlFromReferClient = e.toString()
                        }
                    }
                    InstallReferrerClient.InstallReferrerResponse.FEATURE_NOT_SUPPORTED -> {
                        urlFromReferClient = "FEATURE_NOT_SUPPORTED"
                }
                    InstallReferrerClient.InstallReferrerResponse.SERVICE_UNAVAILABLE -> {
                        urlFromReferClient = "SERVICE_UNAVAILABLE"
                    }
                }
            }

            override fun onInstallReferrerServiceDisconnected() {
                // Try to restart the connection on the next request to
                // Google Play by calling the startConnection() method.
            }
        })
