Codename1 - Values not assigned to variables

Question

Am calling the method GetVal() in another method MyVimeo().

The variables timestamp, nonce, sign are global and printed inside the method GetVal(). However the values are blank when the same are printed in the MyVimeo() method.

Is there any alternative to return the values from GetVal() as String ?

public void GetVal(final String param) {

            NetworkManager networkManager = NetworkManager.getInstance();
            networkManager.start();
            networkManager.addErrorListener(new ActionListener() {

                public void actionPerformed(ActionEvent evt) {
                    NetworkEvent n = (NetworkEvent) evt;
                    n.getError().printStackTrace();
                }
            });

            ConnectionRequest request = new ConnectionRequest() {

                int chr;
                StringBuffer sb = new StringBuffer();
                public String response = "";

                public void readResponse(InputStream input)
                        throws IOException {
                    // do something with input stream
                    while ((chr = input.read()) != -1) {
                        sb.append((char) chr);
                        //System.out.println("reading...");
                    }
                    response = sb.toString();
                    res = response;
                    Log.p("param->" + param);
                    if(param=="timestamp") {
                        timestamp = res;

Answer 1

addToQueue is asynchronous so it already works on a separate thread and you don't need to call it from another thread (and you really shouldn't do that).

You can use addToQueueAndWait but you are better off just calling the rest of your processing code after the data is fetched.
