Using HttpClient and HttpPost in Android with post parameters

You can actually send it as JSON the following way:

// Build the JSON object to pass parametersJSONObject jsonObj = new JSONObject();jsonObj.put("username", username);jsonObj.put("apikey", apikey);// Create the POST object and add the parametersHttpPost httpPost = new HttpPost(url);StringEntity entity = new StringEntity(jsonObj.toString(), HTTP.UTF_8);entity.setContentType("application/json");httpPost.setEntity(entity);HttpClient client = new DefaultHttpClient();HttpResponse response = client.execute(httpPost);

have you tried doing it without the JSON object and just passed two basicnamevaluepairs?also, it might have something to do with your serversettings

Update:this is a piece of code I use:

InputStream is = null;ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();    nameValuePairs.add(new BasicNameValuePair("lastupdate", lastupdate)); try {        HttpClient httpclient = new DefaultHttpClient();        HttpPost httppost = new HttpPost(connection);        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));        HttpResponse response = httpclient.execute(httppost);        HttpEntity entity = response.getEntity();        is = entity.getContent();        Log.d("HTTP", "HTTP: OK");    } catch (Exception e) {        Log.e("HTTP", "Error in http connection " + e.toString());    }

I've just checked and i have the same code as you and it works perferctly.The only difference is how i fill my List for the params :

I use a : ArrayList<BasicNameValuePair> params

and fill it this way :

 params.add(new BasicNameValuePair("apikey", apikey);

I do not use any JSONObject to send params to the webservices.

Are you obliged to use the JSONObject ?
