I am trying to develop an app with voice commands to do different actions within my app. But to fire up the Speech listener module I want to use something like the Google's "OK Google" command which works without any manual touch input. This will help make my app completely hands-free.
Instead of re-creating what the google's service does, I wanted to know if it's possible to receive an event when "Ok google" is triggered.
Note: that this has to work only when my app is running not when it is closed.
