Don't reinvent the wheel. Use Apache HttpClient. Read this javadoc page for an example of a post containing a file upload and a string parameter:

  File f = new File("/path/fileToUpload.txt");
  PostMethod filePost = new PostMethod("http://host/some_path");
  Part[] parts = {
      new StringPart("param_name", "value"),
      new FilePart(f.getName(), f)
  };
  filePost.setRequestEntity(
      new MultipartRequestEntity(parts, filePost.getParams())
      );
  HttpClient client = new HttpClient();
  int status = client.executeMethod(filePost);

You should have tagged your question with android. Android bundles the apache HttpClient, but without this class. Nevertheless, it seems that it's easy enough to add it. Read the following Google groups post: groups.google.com/group/android-developers/msg/1ea124b384da9dc2. You'll need to use the mime4j and httpmime libraries.
