Submit form with POST data in Android app

Question

I\'ve been searching the web for a way to do this for about a week now, and I just can\'t seem to figure it out.

I\'m trying to implement an app that my college can use

Based on @RobbyPonds answer, for the benefit of people wandering past here, below is a generic implementation to post and receive a response from a URI (NOTE Also contains waiting implementation to return a response, probably not every day implementation of network call):

private static String responseValue;

@SuppressWarnings({ "unchecked", "rawtypes" })  
public static String sendPostToTargetAndWaitForResponse() throws ClientProtocolException, IOException {     
    final Thread currentThread = Thread.currentThread();
    synchronized (currentThread) {      

        HttpParams params = new BasicHttpParams();
        HttpClient client = new DefaultHttpClient(params);
        HttpPost post = new HttpPost(HTTP_POST_URI);

        // List Creation with post data for UrlEncodedFormEntity
        ArrayList<NameValuePair> mList = new ArrayList<NameValuePair>();
        mList.add(new NameValuePair() {

            @Override
            public String getValue() {
                return getSampleJSON();
            }

            @Override
            public String getName() {
                return "json";
            }
        });
        post.setEntity(new UrlEncodedFormEntity(mList)); // with list of key-value pairs
        client.execute(post, new ResponseHandler(){

            @Override
            public Object handleResponse(HttpResponse response) throws ClientProtocolException, IOException {
                responseValue = EntityUtils.toString(response.getEntity(), "UTF-8");
                synchronized (currentThread) {                          
                    currentThread.notify();
                }
                return null;
            }
        }); 
        try {
            currentThread.wait();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return responseValue;
    } 
}

What's wrong with them just using the built in browser? You can also submit a form using UrlEncodedFormEntity and HttpClient.

HttpParams params = new DefaultHttpParams(); // setup whatever params you what
HttpClient client = new DefaultHttpClient(params);
HttpPost post = new HttpPost("someurl");
post.setEntity(new UrlEncodedFormEntity()); // with list of key-value pairs
client.execute(post, new ResponseHandler(){}); // implement ResponseHandler to handle response correctly.

Okay and after you have the response in a string. The response since its a page is going to be in html. You need to use a WebView to show the html. WebView has a method loadData() that takes a string of html and displays it.
