In Unity 5.6, how to get inputs in Daydream mode without installing GVR SDK?

Question

I am working on Unity 5.6.5f1 with VR enabled and Daydream selected for an Android app. So my application is working with daydream but I would like to get inputs from the Daydream remote (only a simple click). Is that possible without including the GVR sdk to my project?

Alternatively, can I catch a click on the on/off button or the sound level button of the phone in my app?

Answer 1

You need to import the GVR unity package so that you can access the GVRController class. Only then can you get the on click event.

Answer 2

I finally managed to catch clicks on the volume up and down buttons of the daydream remote control thanks to this post. Quite an ugly solution but it does the trick and provides two inputs.
