How do I persist cookies when using HTTPUrlConnection?

Question

I\'ve begun using the recommended HTTPUrlConnection and moved away from the DefaultHTTPClient. One of the things that I haven\'t been able to glue

Its' taken me a few hours but I managed to build a custom cookie storage myself.

You have to attach this by doing this:

public class application extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
       CookieManager cmrCookieMan = new CookieManager(new MyCookieStore(this.objContext), CookiePolicy.ACCEPT_ALL);
       CookieHandler.setDefault(cmrCookieMan);
       }
    }

Here's the actual storage:

/*
 * This is a custom cookie storage for the application. This
 * will store all the cookies to the shared preferences so that it persists
 * across application restarts.
 */
class MyCookieStore implements CookieStore {

    /*
     * The memory storage of the cookies
     */
    private Map> mapCookies = new HashMap>();
    /*
     * The instance of the shared preferences
     */
    private final SharedPreferences spePreferences;

    /*
     * @see java.net.CookieStore#add(java.net.URI, java.net.HttpCookie)
     */
    public void add(URI uri, HttpCookie cookie) {

        System.out.println("add");
        System.out.println(cookie.toString());

        List cookies = mapCookies.get(uri);
        if (cookies == null) {
            cookies = new ArrayList();
            mapCookies.put(uri, cookies);
        }
        cookies.add(cookie);

        Editor ediWriter = spePreferences.edit();
        HashSet setCookies = new HashSet();
        setCookies.add(cookie.toString());
        ediWriter.putStringSet(uri.toString(), spePreferences.getStringSet(uri.toString(), setCookies));
        ediWriter.commit();

    }

   /*
    * Constructor
    * 
    * @param  ctxContext the context of the Activity
    */
    @SuppressWarnings("unchecked")
    public MyCookieStore(Context ctxContext) {

        spePreferences = ctxContext.getSharedPreferences("CookiePrefsFile", 0);
        Map prefsMap = spePreferences.getAll();

        for(Map.Entry entry : prefsMap.entrySet()) {

            for (String strCookie : (HashSet) entry.getValue()) {

                if (!mapCookies.containsKey(entry.getKey())) {

                    List lstCookies = new ArrayList();
                    lstCookies.addAll(HttpCookie.parse(strCookie));

                    try {

                        mapCookies.put(new URI(entry.getKey()), lstCookies);

                    } catch (URISyntaxException e) {

                        e.printStackTrace();

                    }

                } else {

                    List lstCookies = mapCookies.get(entry.getKey());
                    lstCookies.addAll(HttpCookie.parse(strCookie));

                    try {

                        mapCookies.put(new URI(entry.getKey()), lstCookies);

                }

                System.out.println(entry.getKey() + ": " + strCookie);

            }

        }
