Capturing HTTP Requests and rewrite post Request

Question

I use

1. android emulator (memu).
2. Drony - to install proxy for applications. (works socks5)

I need to change post request from application to server.

I am currently looking at traffic using the http toolkit. But this tool is inconvenient for me because there are many emulators

What I would like.

1. View traffic in real time http: port
2. Send a modified post request from the application to the server

Is it real or not?
