Turn-Based Multiplayer Quick Start

The Google guide for Turn-based Multiplayer Support in Android Games walks through how to start a new match using the default UI using getSelectedOpponentsIntent(). It also mentions the following:

Alternatively, you can implement a Quick Start button to let users bypass the player picker UI, and instead use some default criteria to build the match.
