No meu aplicativo, envio uma solicitação POST para um servidor e recebo uma resposta do servidor. E, a partir da resposta, recolho cookies diferentes, informações do usuário especificamente. Portanto, envio uma solicitação de login e recebo os cookies após a resposta do servidor, para manter o login. No Android 4.3 e abaixo, recebo os cookies e o usuário faz login com êxito. Mas no Android 4.4, o usuário faz logon com êxito, mas nenhum cookie está sendo recebido.

O Android mudou algo significativo para que isso ocorra? Aqui está o meu código abaixo, se alguém tiver alguma sugestão.

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

    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);
    connection.setDoOutput(true);
    connection.setUseCaches(false);

}

    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++) {
