Question

I’m working on an android app that has to send and receive information from a 3rd party server. I’m not experienced at this at all, so bear with me if I give too much/too little/not the right kind of information at first.

The API that was provided to send information has the format

https://methodurl.com/username=user&password=pass&key=key&info=infotosend

When I put this URL into my desktops browser, it returns a string, which I’m also trying to get. At least, I’m assuming all it returns is a string, since if I look at the page source, there is just a string, such as “200 OK” or “401 Unauthorized”.

The code I’m using is what I can glean from the web what I’m supposed to use. Unfortunately, for all I know, I’m writing code to do something very different than what I want. I’ve never written code to interact with a server before, so this is all new to me.

Here’s my code:

TextView urlView = (TextView)findViewById(R.id.url_view);

    HttpClient client = new DefaultHttpClient();
    HttpGet request = new HttpGet(siteToSubmit);
    ResponseHandler<String> responseHandler = new BasicResponseHandler();

    try {
        String serverResponse = client.execute(request, responseHandler);
        urlView.setText(serverResponse);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }   

Logcat in eclipse (when app is running on the emulator) is

java.net.UnknownHostException

The way I understand the code to be working is I’m creating a client that will execute on a url (like would happen when I hit enter in the URL bar on a browser), a request for that client to execute on, and a handler to receive the response from the server, which is set to be recieved as a string. I am then trying to set that string as the text in a TextView to verify that I am getting the proper response. Right now, I just get the log error, and urlView does not change. Any ideas why? Am I understanding the process correctly?

Thanks!
