android - VrPanoramaView angle update listener

Question

How to get current rotation angle change event for VrPanoramaView?

I am building a simple 360 image viewer with VrPanoramaView with an angle icon that shows current angle of the 360 image.

As far as I see, there is no default "navigator" icon for VrPanoramaView, so I am adding manually but I am not able to simple get current rotation angle of 360 image.

There are two ways that image angle will be changed: gyroscope and touch/drag event. I beleive I can add my custom gyroscrope and touch event and manually call getHeadRotation but I am looking for something simple callback from the library.

I don't see any documentation regarding this.

P.S. I am not looking to update to the new Cardboard SDK, which I think is heavy for a simple 360 image viewer. Plus, I don't see any sample code for using Cardboard SDK, other than google's own repo.
