Google Analytics on mobile clients

Question

I am looking for documentation of the protocol used by the mobile Google Analytics SDKs.

In particular I would be interested in:

1. open source library implementing the protocol
2. documentation on the protocol (wire formats)
3. any partial analysis carried out on the protocol

Answer 1

This is a simple HTTP protocol fairly well documented by Google itself. It's called the measurement protocol.
