Extract URL from HttpPost Android

Question

I have a long URL that is being built using nameValuePairs and I'm currently trying to figure out why the post is resulting in a 500 error on some devices while getting a 200 on other devices. I need to extract the full URL from the httppost although as I understand it should just be in the format of:

http://xx.com/site.asmx?var1=blah?var2=blah

And the same build works on phones while not working on tablets. I've tried looking through my code and catching any places where a tablet may not be able to define such variables like this case:

final TelephonyManager tm = (TelephonyManager) getBaseContext()
                .getSystemService(Context.TELEPHONY_SERVICE);
        String tmDevice;
        try{
        tmDevice = "" + tm.getDeviceId().toString();
        }
        catch (NullPointerException e)
        {
            tmDevice = "null";
        }

Here is what some of the nameValuePairs look like and an excerpt from the posting part of the code:

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs
            .add(new BasicNameValuePair("CurrentOwnerUsername", name));
    nameValuePairs.add(new BasicNameValuePair("OSVersion",
            Build.VERSION.RELEASE));
    nameValuePairs.add(new BasicNameValuePair("hash",
            "xxx"));
    nameValuePairs.add(new BasicNameValuePair("OSName", "Android"));
    nameValuePairs.add(new BasicNameValuePair("Model", Build.MODEL));
    nameValuePairs.add(new BasicNameValuePair("Manufacturer",
            Build.MANUFACTURER));
    nameValuePairs.add(new BasicNameValuePair("IMEI", id));
    try {
        nameValuePairs.add(new BasicNameValuePair("SerialNumber",
                Build.SERIAL));
    } catch (NoSuchFieldError e) {
        nameValuePairs.add(new BasicNameValuePair("SerialNumber",
                "NotAvailable"));
    }
    nameValuePairs.add(new BasicNameValuePair("CarrierName", carrier));
    // .add(new BasicNameValuePair("FriendlyName", Build.DEVICE));
    nameValuePairs.add(new BasicNameValuePair("Type", " "));
    nameValuePairs.add(new BasicNameValuePair("VisitorID", VisitorID));
    nameValuePairs.add(new BasicNameValuePair("PhoneNumber", phoneNumber));
    nameValuePairs.add(new BasicNameValuePair("SSID", ssid));
    nameValuePairs.add(new BasicNameValuePair("MACAddress", macAddr));
    nameValuePairs.add(new BasicNameValuePair("UserDepartment",
            department_val));
    nameValuePairs.add(new BasicNameValuePair("BatteryLevel", batteryText));

    int toastDuration = Toast.LENGTH_SHORT;
    try {
        HttpPost httppost = new HttpPost(URL); // post object
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost); // execution
        int result = response.getStatusLine().getStatusCode();
        if (result == 200) {
            CharSequence toastText = "Success";
            Toast.makeText(context, toastText, toastDuration).show();
        } else {
            CharSequence toastText = "Failure";
            Log.d("checkin", String.valueOf(response.getStatusLine()
                    .getStatusCode()));
            Toast.makeText(context, toastText, toastDuration).show();
        }
    } catch (ClientProtocolException e) {
        CharSequence toastText = "ClientProtocolException";
        Toast.makeText(context, toastText, toastDuration).show();
    } catch (IOException e) {
        CharSequence toastText = "IOException";
        Toast.makeText(context, toastText, toastDuration).show();
    }

So what I need is a way to pull the completed URL from the httppost. the current string URL being passed is simply a base url such as : http://xx.com/ and the nameValuePairs follow it. Thoughts?

For HttpPost, the values are passed as the body of the request, so the URL is going to be the same as the one you pass in. You can, however, use EntityUtils.toString(HttpEntity entity) with your UrlEncodedFormEntity to print out the values that will be passed in the HttpPost.
