compile 'com.tmsdurham.actions:actions-on-google:2.0.2'

* use action name from Dialogflow instead of intent name.  The official library changed from using the action field, to using the intent name.  There is a PR open on the official SDK for support for action.  If/when this is merged, this library will be updated to match.
* middleware not supported.  Same functionality can be implemented without lib support by wrapping handlers in fuctions.
