android how to send int and double as namevaluepair as http post

I've an app where i am trying to send data to a webservice using a http post. The user data is a mixture of strings int and doubles. In the app all are represented as Strings as when i use AsyncTask to run the network call, (so that it's not on the main thread), the params array is of type String.

The problem i have is that the server expects an int sometimes. eg compID is an int that the server expects. When using the http post, i use NameValuePair. This will only accept strings. How can i pass an int or a double to the http post?

In my activity.

String[] params = new String[]{tagCompany, tagId, tagPerson, OUT,
null, null,null, null, null, null};
AsyncPostData apd = new AsyncPostData();

private class AsyncPostData extends AsyncTask<String, Void, Void> {

ProgressDialog progressDialog;

protected void onPreExecute()
progressDialog= ProgressDialog.show(NfcscannerActivity.this,
"Connecting to Server"," Posting data...", true);

protected Void doInBackground(String... params) {

nfcscannerapplication.loginWebservice.postData(params[0], params[1], params[2], params[3], params[4],
params[5], params[6], params[7], params[8], params[9]);
return null;

protected void onPostExecute(Void result)
if(progressDialog != null)

}//end of AsyncPostData


My post method

public void postData( String compID, String tagID, String clientID, String carerID,
String phoneScanned, String phoneSent, String TXType, String phoneType, String latitude, String longitude) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://cfweb.yourofficeanywhere.co.uk:88/roadrunner.asmx/PostTransaction");

try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("CompanyID", compID));
nameValuePairs.add(new BasicNameValuePair("TagID", tagID));
nameValuePairs.add(new BasicNameValuePair("ClientID", clientID));
nameValuePairs.add(new BasicNameValuePair("CarerID", carerID));
nameValuePairs.add(new BasicNameValuePair("PhoneScanned", "2010-10-16 16:30 000"));
nameValuePairs.add(new BasicNameValuePair("PhoneSent", "2010-10-16 16:32 000"));
nameValuePairs.add(new BasicNameValuePair("TXType", "2"));
nameValuePairs.add(new BasicNameValuePair("PhoneType", "2"));
nameValuePairs.add(new BasicNameValuePair("Latitude", latitude));
nameValuePairs.add(new BasicNameValuePair("Longitude", longitude));

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);

Log.e(TAG, "response of post = " + response.toString());

} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block

In my post method some of the values are set to null for now. What i would like to know is how to make compID an int in the NameValuePair. compID comes over from the activity as a String but the server expects an int.

You can do something like this:

nameValuePairs.add(new BasicNameValuePair("TXType",Integer.toString (2)));

TxType is the key and 2 is the value
