インストールリファラートラックを実装したいのですが、リファラーパラメーターをバックエンドデータベースに保存したいのですが、多くの例や質問を見てきました.コードを試してみる
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;
}
}
その後、私は自分の活動を試しました
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+" ");
ボタンをクリックしても目的の出力が得られない
からのようなものが欲しい
"https://play.google.com/store/apps/details?id=com.lifestreet.android.TestInstallationIntent&referrer=bb%3DAAAAAAAAAA&feature=search_result%22"
Ans
referrer=bb
よろしくお願いします。
