我想实现安装引荐来源跟踪并希望引荐来源参数和存储在后端数据库中我已经看到很多例子或问题，如 Get Android Google Analytics referrer tag或 Android Google Analytics Campaign tracking not appearing但没有找到我生成链接并尝试代码的方法

   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;
}
}

在那之后我尝试了我的 Activity

 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+" ");

点击按钮但没有得到想要的输出

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

任何帮助我都非常感谢 提前致谢。

最佳答案

不确定 Google 是否允许您发送任意信息。尝试使用生成器创建 url。
