android - send parameters while uploading file

I've got this piece of code http://pastebin.com/VrMNuxcv which successfully uploads a file onto the serve开发者_Go百科r from my android.

I'd like to , however to be able to send a couple of string parameters together with it.

Could you please tell me, if possible, where exactly I need to do this in that piece of code and how?

Thanks Andreas

I assume that you're in control of how the server processes the upload, i.e., you wrote the server code too???

If so, I simply use custom/private request properties (i.e., prefixed x-) for some client/server code I've written. Example...

conn.setRequestProperty("x-myapp-param1", "Parameter 1 text");

Any use to you?
