There are a number of ways to use the MultipartEntity for uploading a file. By far, the most common is something like this.

File file = new File([path to your file]);

MimeTypeMap map = MimeTypeMap.getSingleton();
String ext = FilenameUtils.getExtension(file.getName());
String mime_type = map.getMimeTypeFromExtension(ext);

String userAgent = System.getProperty("http.agent", "Android device");
AndroidHttpClient httpClient = AndroidHttpClient.newInstance(userAgent);

HttpPost httpPost = new HttpPost([your url here]);

MultipartEntity form = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE, this);
form.addPart("file-data", new FileBody(file, mime_type, "UTF-8"));

httpPost.setEntity(form);

HttpResponse httpResponse = httpClient.execute(httpPost);

httpClient.close();

That's a basic example. You should wrap it with appropriate try-catch blocks, etc.

If you want to use the MultipartEntity with the android-async-http project just pass the object to an AsyncHttpClient like this:

File file = new File([path to your file]);

MimeTypeMap map = MimeTypeMap.getSingleton();
String ext = FilenameUtils.getExtension(file.getName());
String mime_type = map.getMimeTypeFromExtension(ext);

MultipartEntity form = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE, this);
form.addPart("file-data", new FileBody(file, mime_type, "UTF-8"));

AsyncHttpClient client = new AsyncHttpClient();
client.post(context, [your url], form, mime_type, responseHandler) ;

Again, just a basic example. Follow the android-async-http project documentation and recommendations for creating the client and response handlers.
