How to use

getContentLength

method

in

org.apache.http.entity.mime.MultipartEntity

 MultipartEntity reqEntity = new MultipartEntity();
// add your ContentBody fields as normal...

// Now, pull out the contents of everything you've added and set it as the payload
ByteArrayOutputStream bos = new ByteArrayOutputStream((int)reqEntity.getContentLength());
reqEntity.writeTo(bos);
oAuthReq.addPayload(bos.toByteArray());

// Finally, set the Content-type header (with the boundary marker):
Header contentType = reqEntity.getContentType();
oAuthReq.addHeader(contentType.getName(), contentType.getValue());

// Sign and send like normal:
service.signRequest(new Token(oAuthToken, oAuthSecret), oAuthReq);
Response oauthResp = oAuthReq.send();
