会话 cookie 在模拟器上可以工作，但在真实设备上无法工作。

androidsessioncookieshttpclientcookiestore

我正在使用Android 2.1开发应用程序。

在使用会话Cookie登录RESTful Web服务时，遇到了问题。代码在模拟器上运行良好，但在我的HTC Magic上运行时，Cookie逻辑不起作用。通过列出Cookie列表（请参见附图），我确认Magic已经在标头中接收到Cookie。有谁能解释为什么Cookie存储区为空，即使它们在标头中也是如此？

  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:

更新 - 我已经在另外两部手机上尝试过了，它们都可以正常工作。但其中一部手机无法处理cookies。唉。 - mvsjes2

好的，这实际上是一次在Apache代码中的寻找。归根结底，问题是cookie已经过期了，所以cookiestore没有任何解释地将它们丢弃了。结果发现手机设置中没有勾选“使用网络日期/时间”。一旦我勾选了这个选项，应用程序就正常工作了。但仍然令人困惑-本地时间已正确设置（误差不超过2分钟）。

来自org.apache.http.impl.client.BasicCookieStore/addCookie：

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