Question

i am trying to post data via HTTP Post using name value key pair. But I am unable to post . The post url is http://mastercp.openweb.co.za/api/dbg_dump.asp .Should I include some header also while posting? Thanks

public class MainActivity extends Activity {
    Button ok;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.profile);
        ok=(Button)findViewById(R.id.but_signup_login);



        ok.setOnClickListener(new OnClickListener() {


            public void onClick(View arg0) {


                System.out.println("Clicked");
        DownloadWebPageTask task = new DownloadWebPageTask();
        task.execute(new String[] { "http://mastercp.openweb.co.za/api/dbg_dump.asp" });}});
    }






    public void postData() {
        // Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://mastercp.openweb.co.za/api/dbg_dump.asp");

        System.out.println("Clicked again");
        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(34);
            String amount ="Ashish";
            nameValuePairs.add(new BasicNameValuePair("User_Type", amount));
            nameValuePairs.add(new BasicNameValuePair("User_Email", "[e-mail]"));

Your postdata() method doesn’t actually do the post. You need to do something like:

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost, new BasicHttpContext());

Then you can process the response (starting by checking the value of response.getStatusLine().getStatusCode()). For instance, if you’re expecting string data in the response:

if (response.getStatusLine().getStatusCode() == 200) {
    BasicResponseHandler handler = new BasicResponseHandler();
    String data = handler.handleResponse(response);
}
