Android App - Listening for Hangouts Dialer Calls

Question

Is there a way to create an application that listens for calls coming through the Google Hangouts and Hangouts apps? I know that there is an API for Hangouts, but I would prefer to create a standalone application that detects events from Hangouts and Hangouts Dialer.

Answer 1

As far as I can tell, for Android there is no Hangouts API, but only a web application.
