会话cookie在模拟器上工作，但不是真实的设备

Question

我正在开发一个使用android 2.1的应用程序。

我使用会话cookie登录到RESTful Web服务时遇到问题。该代码在模拟器上正常工作，但是当我在HTC Magic上运行它时，Cookie逻辑不起作用。我已经确认，通过列出这些魔术曲是通过标题接收cookie（请参阅附件）。任何人都可以说为什么cookie商店即使他们在标题中也是空的吗？

public HttpProvider() { 
    Scheme http = new Scheme("http", new PlainSocketFactory(), 80); 
    SchemeRegistry registry = new SchemeRegistry(); 
    registry.register(http); 

    client = new DefaultHttpClient(new ThreadSafeClientConnManager((new BasicHttpParams()), registry), new BasicHttpParams()); 
    } 

    public void get(Request request) { 
    try { 
     HttpGet get = new HttpGet(request.url); 
     HttpResponse response = client.execute(get); 
     debugListHeaders(response, request.ticket); 
     debugListCookies(); 
    } 
    } 

    void debugListHeaders(HttpResponse response, int ticket) { 
    Header[] headers = response.getAllHeaders(); 
    Log.d(LOG, "Printing all headers" + " (" + ticket + ")"); 
    for (Header header : headers) { 
     Log.d(LOG, "Header name: " + header.getName() + ", value: " + header.getValue() + " (" + ticket + ")"); 
    } 
    Log.d(LOG, "All headers have been printed" + " (" + ticket + ")"); 
    } 

    void debugListCookies() { 
    Log.d(LOG, "List cookies for connection"); 
    for (Cookie cookie : client.getCookieStore().getCookies()) { 
     Log.d(LOG, 
     "Domain: " + cookie.getDomain() + 
     " Name: " + cookie.getName() + 
     " Path: " + cookie.getPath() + 
     " Value: " + cookie.getValue() + 
     " Expires: " + cookie.getExpiryDate().toString() + 
     " IsExpired: " + (cookie.isExpired(new Date()) ? "true" : "false")); 
    } 
    Log.d(LOG, "All cookies have been listed"); 
    } 

Thru the emulator: 
<snipped header list as it's obviously working> 
D/SessionProvider( 257): List cookies for connection

那么，这原来是一个在apache代码中的狩猎探险队。它被归结为饼干已经过期，所以饼干店就把它们扔掉了，没有任何解释。原来手机没有在设置中选中“使用网络日期/时间”。只要我这样做，应用程序运行良好。这仍然令人费解 - 当地时间设置正确（2分钟内）。

从org.apache.http.impl.client.BasicCookieStore /的addCookie：

94 if (!cookie.isExpired(new Date())) { 
95  cookies.add(cookie);
