Android 4.4 KitKat does not receive cookies

Question

In my application, I send a POST request to the server and get a response from the server. And from the answer I collect different cookies, user information. Therefore, I send a login request and receive cookies after the server responds in order to save the login. On Android 4.3 and below, I get cookies that are great and the user logs have completed successfully. But in Android 4.4, the user logs in successfully, but the cookie is not accepted.

Android has changed something important for this? Here is my code below if anyone has any suggestions.

private URL urlObj; private HttpURLConnection connection; private DataOutputStream dataOs; private ArrayList<String> schools; private ArrayList<Post> schoolPosts; private String schoolID; private String name; 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 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); connection.setDoOutput(true); connection.setUseCaches(false); dataOs = new DataOutputStream(connection.getOutputStream()); } //Called after communication is complete private void disconnectAll() throws IOException { connection.disconnect(); dataOs.close(); } private void getCookies() { SharedPreferences settings = context.getSharedPreferences(PREFS_NAME, 0); userLoginCookie = settings.getString(USER_LOGIN, BLANK); Log.d(LOG, "Cookie: "+userLoginCookie); sessionSeedCookie = settings.getString(SESS_SEED, BLANK); Log.d(LOG, "Cookie: "+sessionSeedCookie); sessionUidCookie = settings.getString(SESS_UID, BLANK); Log.d(LOG, "Cookie: "+sessionUidCookie); sPrefCookie = settings.getString(S_PREF, "sPref="+BLANK); Log.d(LOG, "Cookie: "+sPrefCookie); } private void updateCookies() { SharedPreferences settings = context.getSharedPreferences(PREFS_NAME, 0); SharedPreferences.Editor editor = settings.edit(); List<HttpCookie> cookieList = store.getCookies(); for(int i=0; i<cookieList.size(); i++) { if(cookieList.get(i).getName().equals(USER_LOGIN)) editor.putString(USER_LOGIN, cookieList.get(i).toString()); else if(cookieList.get(i).getName().equals(SESS_SEED)) editor.putString(SESS_SEED, cookieList.get(i).toString()); else if(cookieList.get(i).getName().equals(SESS_UID)) editor.putString(SESS_UID, cookieList.get(i).toString()); else Log.d(LOG, "Found Extra Cookie: "+cookieList.get(i).getName()); } sPrefCookie = settings.getString(S_PREF, "sPref="+BLANK); editor.commit(); //Save changes to the SharedPreferences } //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"; dataOs.writeBytes(query); Log.d(LOG, "" + connection.getResponseCode()); updateCookies(); String response = readInputAsString(connection.getInputStream()); Log.d(LOG, "Connection Status: "+response); disconnectAll(); return response; } //Logs user out of Walkntrade public void logout() throws IOException { establishConnection(); String query = "intent=logout"; dataOs.writeBytes(query); Log.d(LOG, "" + connection.getResponseCode()); updateCookies(); disconnectAll(); } //Returns user login status public static boolean isUserLoggedIn(Context _context) { SharedPreferences settings = _context.getSharedPreferences(PREFS_NAME, 0); boolean isUserLoggedIn = settings.getBoolean(DataParser.CURRENTLY_LOGGED_IN, false); return isUserLoggedIn; } public String getUserName() throws IOException{ establishConnection(); String query = "intent=getUserName"; dataOs.writeBytes(query); Log.d(LOG, ""+connection.getResponseCode()); updateCookies(); String response = readInputAsString(connection.getInputStream()); disconnectAll(); return response; } public String getUserAvatar() throws IOException { establishConnection(); String query = "intent=getAvatar"; dataOs.writeBytes(query); Log.d(LOG, ""+connection.getResponseCode()); updateCookies(); String response = readInputAsString(connection.getInputStream()); disconnectAll(); return response; }

I fixed the problem. I switched from HttpUrlConnection and other java.net stuff to AndroidHttpClient and other Apache Http classes. Cookies are now retrieved from Android API 19.

[EDIT] I used AndroidHttpClient ( http://developer.android.com/reference/android/net/http/AndroidHttpClient.html ) and I followed several Apache Http tutorials. So after I changed the code a bit, it looks like this:

 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 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; }

This code worked fine for me before the KitKat 4.4 update -

 HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); //handle cookies CookieManager cookieManager = new CookieManager(); CookieHandler.setDefault(cookieManager); 

It broke after 4.4.2 (at least when I noticed this) and cookies were no longer received. Just by moving the CookieManager and CookieHandler before opening urlConnection, he fixed it again .. it is strange that it worked before! eg.

 //handle cookies CookieManager cookieManager = new CookieManager(); CookieHandler.setDefault(cookieManager); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
