How to display a 3D Model over a 2D maker (QRCode) using ARCore?

Question

I'm doing tests with the sample Hello AR from the ARCore SDK 1.0. How can I display a 3D Model over a 2D maker, like a QRCode? Is there any class that detects the QRCode position at the ARCore API, or should I do that with an external lib?

At the sample application, the Android Robot (Andy) is shown when the surface is clicked. I wanna show Andy over the 2D marker.

As of now this feature is not supported. Hopefully they will do so in the future. You can't even control the camera's focus so i don't know how you could recognise anything other than the grid.
