Android uploads both file and key-value pairs.

==================== Problem Description ====================
I'm going to upload an audio or image file now, but at the same time, we'll upload the suffix of the file in the same way as the key-value pair.
And this file is written directly with the stream .... Cannot be passed in the form of the key value of entity.
How to solve.
==================== Solution 1====================
Using the Apache Httpcomm Toolkit, there is a fiileentity class. It's OK to put the file path directly in.
==================== Solution 2====================
Keep the session, upload the file successfully, then upload the key value pair.
