61This sample demonstrates how to use basic functionalities of Camera2
62API. You can learn how to iterate through characteristics of all the
63cameras attached to the device, display a camera preview, and take
64pictures.

70The [Camera2 API][1] provides an interface to individual camera
71devices connected to an Android device. It replaces the deprecated
72Camera class.
73
74Use [getCameraIdList][2] to get a list of all the available
75cameras. You can then use [getCameraCharacteristics][3] and find the
76best camera that suits your need (front/rear facing, resolution etc).
77
78Create an instance of [CameraDevice.StateCallback][4] and open a
79camera. It is ready to start camera preview when the camera is opened.
80
81This sample uses TextureView to show the camera preview. Create a
82[CameraCaptureSession][5] and set a repeating [CaptureRequest][6] to it.
83
84Still image capture takes several steps. First, you need to lock the
85focus of the camera by updating the CaptureRequest for the camera
86preview. Then, in a similar way, you need to run a precapture
87sequence. After that, it is ready to capture a picture. Create a new
88CaptureRequest and call [capture][7]. Don't forget to unlock the focus
89when you are done.
