如何在Android中使用google track获取引荐来源？

Question

我想实现安装引用跟踪并希望引用参数和存储在后端数据库中我已经看到许多例子或问题,如获取Android Google Analytics引用标记或Android Google Analytics广告系列跟踪未显示但没有获得我生成链接的方式去尝试代码

   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+" ");

按钮单击但没有获得所需的输出

我想要类似的东西

"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感谢.

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。
