在Android中制作ConnectionRequest的最佳方式

Question

I coded this connection request using codenameone. I will like to know the best way to do the same thing on android. Any help please. I have searched around and not really getting anything solid. This is what I want to do. Thanks.

public void doLogin(String username, String password) {

    ConnectionRequest cr;
    cr = new ConnectionRequest() {
        Hashtable h;

        @Override
        protected void postResponse() {

        }

        @Override
        protected void readResponse(InputStream input) throws IOException {
            JSONParser parser = new JSONParser();
            h = parser.parse(new InputStreamReader(input));
            System.out.println("" + h);
            String username = (String) h.get("username");

            if (username != null) {
                user = username;
                showForm("Dashboard", null);

            }

        }

        @Override
        protected void handleErrorResponseCode(int code, String message) {
            if (code == 401) {
                Dialog.show("Failure", "Invalid Username or Password", "OK", null);
            }
        }

        @Override
        protected void handleException(Exception err) {
            Dialog.show("Failure", "Check Network", "OK", null);
        }

    };

    cr.addRequestHeader(AppConfig.REQUEST_HEADER, AppConfig.REQUEST_HEADER_VALUE);
    cr.setContentType(AppConfig.CONTENT_TYPE);
    cr.setUrl(AppConfig.BASE_URL + "authentication?username=" + username + "&password=" + password);
    cr.setPost(true);
    cr.setReadResponseForErrors(true);
    InfiniteProgress prog = new InfiniteProgress();
    Dialog dlg = prog.showInifiniteBlocking();
    cr.setDisposeOnCompletion(dlg);
    NetworkManager.getInstance().addToQueue(cr);

}

We support BluetoothLE which is where the industry is going. I would suggest avoiding that entirely for this use case and using a native interface to the OS's printing API's which are currently unmapped in Codename One.

For Android you can use the standard java.net.URL code and the org.json parsing API.
