I want to build an apk(Named commander) to use Google assistant(SDK), the feature designed below: 1:control some device, for example. Just say"Ok google, set the brightness to 100" or "Ok google, take a picture now."
2:Use default google assistant's feature, for example. "Ok google, call lucy" or "Ok google, send a message to Lucy to ask her to have breakfast"
3:Send command directly without say "Ok google, let's talk to commander"
My question is that, is Actions on Google just build an app which is plugged in google assistant app? Could user call my own app to do something when receive the actions on google.
For example: User say "ok google, call lucy" this command will deliver to google own assistant to handle it, and when user say "ok google, set the brightness to 100" will response an action to my owner app with parameter(100) in a intent?
Could I implement it ?
