This android tutorial focuses on completing the setup for the camera2 surface preview session.
The first step is to create a camera2 surface based on the TextureView.
Then create a CaptureRequestBuilder using the CameraDevice and add the camera2 surface to the CaptureRequestBuilder.
Next use the CameraDevice to create a CameraCaptureSession and include the surface preview and capture session StateCallback as arguments.
In the CameraCaptureSession's onConfigured method setup the CaptureRequest, initialise the CameraCaptureSession member and then call the CameraCaptureSession's setRepeatingRequest method.
It also pays to setup a toast in the CameraCaptureSession's onConfigureFailed in case something has gone wrong.

API's covered:
SurfaceTexture
SurfaceTexture.setDefaultBufferSize
Surface
CaptureRequest.Builder
CaptureRequest.Builder.build
CaptureRequest.addTarget
CameraDevice
CameraDevice.createCaptureRequest
CameraCaptureSession.StateCallback
CameraCaptureSession.setRepeatingRequest
