Content length? Length required but set?

Question

I am trying to send data to a web server using a post, this is what I have so far:

private void entity(String id, String file)
                throws JSONException, UnsupportedEncodingException, FileNotFoundException {
             // Add your data
            File myFile = new File(
                    Environment.getExternalStorageDirectory(), file);
            InputStreamEntity reqEntity = new InputStreamEntity(
                    new FileInputStream(myFile), myFile.length());

            reqEntity.setContentType("text/csv");
            reqEntity.setChunked(true); // Send in multiple parts if needed

            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
            nameValuePairs.add(new BasicNameValuePair("project", id));

            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            httppost.setEntity(reqEntity);

            //httppost.setHeader("Content-Length", String.valueOf(myFile.length()));

        }

When I send the post request it comes back with content-length required, but isn't that set here?

InputStreamEntity reqEntity = new InputStreamEntity(
                    new FileInputStream(myFile), myFile.length());

I don't know if what I am doing is right or not, please help, thanks

Edit -

When I try to set the content-length myself using

httppost.setHeader("Content-Length", String.valueOf(myFile.length()));

it comes back with header already set.

Hence why it is commented out

In my case using

reqEntity.setChunked(false);

solved the problem.

That sets the length of the content for the InputStreamEntity which is used locally when writing the data to the OutputStream. It doesn't set that value as a parameter for your request. You'll need to set that header yourself.

Oh, I think I see why. You're setting the entity twice. Why? – Jason Robinson Apr 19 '12 at 22:18
`httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));` followed by `httppost.setEntity(reqEntity);` – Jason Robinson Apr 19 '12 at 22:34
Ahh yeah, how would I add them both then? – FabianCook Apr 19 '12 at 22:44

You may want to use MultipartEntity and add parts using addPart methods with StringBody and InputStreamBody (or) FileBody

I don't believe Android uses this? – FabianCook Apr 19 '12 at 23:19
@SmartLemon My bad. Just by looking at the class names, I thought you were using Apache HttpClient. – srkavin Apr 19 '12 at 23:23
Thanks for answer though, in general Java that works so accept :P – FabianCook Apr 20 '12 at 00:50
