Android 4.4 KitKat未收到Cookie

Question

在我的应用程序中，我向服务器发送POST请求，并从服务器接收响应。 从响应我收集不同的cookie，特别是用户信息。所以，我发送一个登录请求，并在服务器响应后接收cookie，以坚持登录。在Android 4.3及以下版本中，我收到的cookies很好，用户登录成功。但在Android 4.4中，用户成功登录，但没有收到cookie。

Android已经改变了一些重要的事情发生？如果有人有任何建议，以下是我的代码。

private URL urlObj; 
private HttpURLConnection connection; 
private DataOutputStream dataOs; 


private ArrayList<String> schools; 
private ArrayList<Post> schoolPosts; 
private String schoolID;

private String userLoginCookie, sessionSeedCookie, sessionUidCookie, sPrefCookie; 

private Context context; 
private CookieStore store; 

public DataParser(Context _context) { 
    context = _context; 
} 

//First call whenever connecting across the user's network 
private void establishConnection() throws IOException { 
    urlObj = new URL(url); 
    connection = (HttpURLConnection) urlObj.openConnection(); 
    CookieManager cookieManager = new CookieManager(); 

    cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL); 
    CookieHandler.setDefault(cookieManager); 
    store = cookieManager.getCookieStore(); 

    getCookies(); 
    connection.setRequestMethod("POST"); 
    connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded"); 
    connection.setRequestProperty("Cookie", sessionSeedCookie+";"+sessionUidCookie+";"+userLoginCookie+";"+sPrefCookie);

我修复了这个问题。我从HttpUrlConnection和其他java.net的东西切换到AndroidHttpClient和其他Apache Http类。 Cookies现在从Android API 19检索。

[编辑] 我使用AndroidHttpClient（http://developer.android.com/reference/android/net/http/AndroidHttpClient.html），我跟着几个Apache Http教程。所以，以后我就变卦了一点点的代码，它看起来像这样：

private AndroidHttpClient httpClient; //Android Client, Uses User-Agent, and executes request 
private HttpContext httpContext; //Contains CookieStore that is sent along with request 
private CookieStore cookieStore; //Holds cookies from server 
private HttpPost httpPost; //Contains message to be sent to client 
private final String USER_AGENT = System.getProperty("http.agent"); //Unique User-Agent of current device 

//First call whenever connecting across the user's network 
private void establishConnection() { 
    cookieStore = new BasicCookieStore(); 
    httpContext = new BasicHttpContext(); 
    httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore); //Attach CookieStore to the HttpContext 

    getCookies(); //Retrieve currently stored cookies 

    httpClient = AndroidHttpClient.newInstance(USER_AGENT); 
    httpPost = new HttpPost(url); 
    httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded"); 
    httpPost.setHeader("Cookie", sessionSeedCookie + ";" + sessionUidCookie + ";" + userLoginCookie + ";" + sPrefCookie); 
} 

//Called after communication is complete 
private void disconnectAll() { 
    httpClient.close(); 
} 

//Sends out POST request and returns an InputStream 
private InputStream processRequest(String query) throws IOException{ 
    httpPost.setEntity(new StringEntity(query)); //wraps the query into a String entity 
    HttpResponse response = httpClient.execute(httpPost, httpContext); //Executes the request along with the cookie store 
    Log.i(TAG, "Server Response Code: " + response.getStatusLine().getStatusCode()); //Reads response code from server 

    updateCookies(); 

    return response.getEntity().getContent(); 
} 

//Logins User into Walkntrade 
public String login(String email, String password) throws IOException { 
    establishConnection(); //Instantiate all streams and opens the connection 
    String query= "intent=login&password="+password+"&email="+email+"&rememberMe=true"; 

    InputStream inputStream = processRequest(query); 
    String serverResponse = readInputAsString(inputStream); //Reads message response from server 

    disconnectAll(); 
    return serverResponse; 
}

此代码之前，奇巧的工作对我罚款4.4更新 -

HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); 

//handle cookies 
CookieManager cookieManager = new CookieManager(); 
CookieHandler.setDefault(cookieManager); 

它4.4.2爆发后（在至少在我注意到它的时候），cookies不再被接收。在打开urlConnection之前简单地移动CookieManager和CookieHandler就可以修复它了。奇怪的是，它之前的工作！例如。

//handle cookies 
CookieManager cookieManager = new CookieManager(); 
CookieHandler.setDefault(cookieManager); 

HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
