submit html form programmatically in android

Question

I want to submit form programatically in android. I don't want any user interaction with web browser. User will provide inputs in EditField and then inputs will be submitted thru httppost method via HTTPwebmethod. But I didn't get any success in the same. Please advise. I have used HTMLUnit in java but its not working android.

  final WebClient webClient = new WebClient();
 final HtmlPage page1 = webClient.getPage("http://www.mail.example.com");
     final HtmlForm form = page1.getHtmlElementById("loginform");

    final HtmlSubmitInput button = form.getInputByName("btrn");
    final HtmlTextInput textField1 = form.getElementById("user");
   final HtmlPasswordInput textField2 =          form.getElementById("password");textField1.setValueAttribute("user.name");
    textField2.setValueAttribute("pass.word"); final HtmlPage page2 = button.click();

Oops. Sorry. Looks like you are trying to POST through the browser afterall.

Here's a snippet I've been using to do an HTTP POST on Android without going through the web browser:

HttpClient httpClient = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(httpClient.getParams(), TIMEOUT_MS);
HttpConnectionParams.setSoTimeout(httpClient.getParams(), TIMEOUT_MS);
HttpPost httpPost = new HttpPost(url);  
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
nameValuePairs.add(new BasicNameValuePair("name1", "value1"));  
nameValuePairs.add(new BasicNameValuePair("name2", "value2")); 
nameValuePairs.add(new BasicNameValuePair("name3", "value3"));   
// etc...
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
HttpResponse response = httpClient.execute(httpPost);

I think that should work for what you're trying to do. I have TIMEOUT_MS set to 10000 (so, 10 seconds)

Then you can read out the server's response using something like this:

BufferedReader br = new BufferedReader(new InputStreamReader(response.getEntity().getContent()), 8096);
