Android Camera2Basic Sample
This sample demonstrates how to use basic functionalities of Camera2 API. You can learn how to iterate through characteristics of all the cameras attached to the device, display a camera preview, and take pictures.
The Camera2 API provides an interface to individual camera devices connected to an Android device. It replaces the deprecated Camera class.
Create an instance of CameraDevice.StateCallback and open a camera. It is ready to start camera preview when the camera is opened.
Still image capture takes several steps. First, you need to lock the focus of the camera by updating the CaptureRequest for the camera preview. Then, in a similar way, you need to run a precapture sequence. After that, it is ready to capture a picture. Create a new CaptureRequest and call [capture]. Don't forget to unlock the focus when you are done.
