Question

我想实现install referrer track并希望在后端数据库中使用referrer参数和存储我已经看到了许多例如Get Android Google Analytics referrer tag或Android Google Analytics Campaign tracking not appearing的问题，但没有得到我生成链接的方法去尝试代码

   package SimpleDemo.ReferralTrack; 

   import java.io.UnsupportedEncodingException;
   import java.net.URLDecoder;
   import java.util.HashMap;
   import java.util.Map;

   import android.content.BroadcastReceiver;
   import android.content.Context;
   import android.content.Intent;
   import android.content.SharedPreferences;
   import android.os.Bundle;

  public class ReferralReceiver extends BroadcastReceiver
   {
@Override
public void onReceive(Context context, Intent intent)
{
    // Workaround for Android security issue: http://code.google.com/p/android/issues/detail?id=16006
    try
    {
        final Bundle extras = intent.getExtras();
        if (extras != null) {
            extras.containsKey(null);
        }
    }
    catch (final Exception e) {
        return;
    }

    Map<String, String> referralParams = new HashMap<String, String>();

    // Return if this is not the right intent.
    if (! intent.getAction().equals("com.android.vending.INSTALL_REFERRER")) { //$NON-NLS-1$
        return;
    }

    String referrer = intent.getStringExtra("referrer"); //$NON-NLS-1$
    if( referrer == null || referrer.length() == 0) {
        return;
    }

    try
    {    // Remove any url encoding
        referrer = URLDecoder.decode(referrer, "x-www-form-urlencoded"); //$NON-NLS-1$
    }
    catch (UnsupportedEncodingException e) { return; }

    // Parse the query string, extracting the relevant data
    String[] params = referrer.split("&"); // $NON-NLS-1$
    for (String param : params)
    {
        String[] pair = param.split("="); // $NON-NLS-1$
        referralParams.put(pair[0], pair[1]);
    }

    ReferralReceiver.storeReferralParams(context, referralParams);
}

private final static String[] EXPECTED_PARAMETERS = {
    "utm_source",
    "utm_medium",
    "utm_term",
    "utm_content",
    "utm_campaign"
};
private final static String PREFS_FILE_NAME = "ReferralParamsFile";

/*
 * Stores the referral parameters in the app's sharedPreferences.
 * Rewrite this function and retrieveReferralParams() if a
 * different storage mechanism is preferred.
 */
public static void storeReferralParams(Context context, Map<String, String> params)
{
    SharedPreferences storage = context.getSharedPreferences(ReferralReceiver.PREFS_FILE_NAME, Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = storage.edit();

    for(String key : ReferralReceiver.EXPECTED_PARAMETERS)
    {
        String value = params.get(key);
        if(value != null)
        {
            editor.putString(key, value);
        }
    }

    editor.commit();
}

/*
 * Returns a map with the Market Referral parameters pulled from the sharedPreferences.
 */
public static Map<String, String> retrieveReferralParams(Context context)
{
    HashMap<String, String> params = new HashMap<String, String>();
    SharedPreferences storage = context.getSharedPreferences(ReferralReceiver.PREFS_FILE_NAME, Context.MODE_PRIVATE);

    for(String key : ReferralReceiver.EXPECTED_PARAMETERS)
    {
        String value = storage.getString(key, null);
        if(value != null)
        {
            params.put(key, value);
        }
    }
    return params;
}
}

之后我尝试了我的活动

 SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(DemoActivity.this);
              String  referrers1 =preferences.getString("ga_campaign", "0");
              Map<String, String> retrieveReferralParams=ReferralReceiver.retrieveReferralParams(DemoActivity.this);
              String  referrers2= retrieveReferralParams.get("utm_source");
              String  referrers3= retrieveReferralParams.get("utm_medium");
              String  referrers4= retrieveReferralParams.get("utm_term");
              String  referrers5= retrieveReferralParams.get("utm_content");
              String  referrers6= retrieveReferralParams.get("utm_campaign");
              tv.setText(referrers1+" "+referrers2+" "+referrers3+" "+referrers4+" "+referrers5+" "+referrers6+" ");

点击按钮但没有获得所需的输出

我想要来自

的东西

"https://play.google.com/store/apps/details?id=com.lifestreet.android.TestInstallationIntent&referrer=bb%3DAAAAAAAAAA&feature=search_result%22"  
 Ans     

   referrer=bb

任何帮助我高度赞赏提前谢谢。

不确定Google是否允许您发送任意信息。尝试使用生成器来创建URL。

Answer 2

我遇到过类似的问题。发现它是生命周期问题：在我的应用程序的onResume（）之后，在SAME主线程上调用了install_referrer接收器的onReceive，因此在onResume（）期间读取referrer文件的任何尝试都会失败。以下是用于证明它的logcat，使用Android 4.2.1和4.4.2在2台设备上反复100％重现：

首先，Play商店在单独的（商店）流程中将引荐者广播到包：

11-04 14:17:51.558: D/Finsky(1737): [1] ReferrerRebroadcaster.doBroadcastInstallReferrer: Delivered referrer for com.xxx.demo

app onResume（） - 仍然没有激活广播接收器！小号

11-04 14:17:51.888: D/XXX Main Activity(22730): onResume

应用程序尝试读取引用者（接收者应使用getSharedPreferences.putString存储它）：

11-04 14:17:51.958: I/XXX(22730): Extracted install referrer:

现在只在主线程上调用接收器，并且很快就会尝试将引用者写入文件：

11-04 14:17:51.918: I/XXX(22730): Received install referrer: abcdefg

正如您所看到的，onResume（）没有机会实际读取文件，因此提取无效。但是，如果我关闭应用程序并重新打开它，onResume现在能够找到该文件并且引用者字符串被处理 - 但不是在第一次启动时：）

希望这有帮助！

Google Analytics在其SDK中使用任意常量。对于campaing_source是＆amp; cs。

如何在Android中使用google track获取引荐来源？
