获取Android Google Analytics引荐来源代码

Question

我们计划使用Google Analytics跟踪广告点击推介,通过Android电子市场推广到我们的应用程序.

根据Google文档,引荐来源代码是通过意图实现的,并由Google Analytics资源库自动记录.

这很好,但我们需要为我们自己的内部分析提取引用标记.该文档很少关于如何从初始启动意图中获取它的详细信息,以及有关如何在上线之前模拟它的说明.

有任何人对此有经验吗？

Answer 1

我继续发布了一个死像素查找器应用程序,以窥探意图.出于某种原因,当我注册两个不同的广播接收器(即com.google.android.apps.analytics.AnalyticsReceiver和我自己的)时,我从未接收过它.

因此,我只注册了自己的接收器,处理信息,并将其传递给Google Analytics.不知道这是多么犹豫,但它确实有效.代码如下.

public class ZSGoogleInterceptor extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();

        String referrerString = extras.getString("referrer");
        // Next line uses my helper function to parse a query (eg "a=b&c=d") into key-value pairs
        HashMap<String, String> getParams = Utility.getHashMapFromQuery(referrerString);
        String source = getParams.get("utm_campaign");

        if (source != null) {
            SharedPreferences preferences = context.getSharedPreferences("my_prefs", Context.MODE_PRIVATE);
            Editor preferencesEditor = preferences.edit();
            preferencesEditor.putString("ga_campaign", source);
            preferencesEditor.commit();
        }

        // Pass along to google
        AnalyticsReceiver receiver = new AnalyticsReceiver();
        receiver.onReceive(context, intent);
    }

}

然后,当您的应用程序实际启动时,您可以将值从共享首选项中拉回来,并将其与用户注册或其他任何内容一起传递.我将广告系列代码用于我的目的,但您可以从使用此工具创建的引荐来源字符串中获取所需的任何参数.

在你的清单文件中:

        <receiver android:name="com.google.android.gms.analytics.CampaignTrackingReceiver" />

        <!-- Make sure this points to the location of Referrer Receiver in your package -->
        <receiver android:name=".ReferrerReceiver" android:exported="true">
            <intent-filter>
                <action android:name="com.android.vending.INSTALL_REFERRER" />
            </intent-filter>
        </receiver>
