我想实现安装引荐来源网址跟踪并希望引荐来源网址参数并存储在后端数据库中我已经看到了许多示例或问题，例如获取 Android Google Analytics 引荐来源标签或Android Google Analytics Campaign 跟踪没有出现但没有获得我生成链接的方式并尝试代码
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+" ");
单击按钮但未获得所需的输出
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
任何帮助我都非常感谢提前谢谢。
