Camera2 API is an upgraded model of the Camera device. Today you look at many apps with rich camera features in markets like Instagram and Snapchat. Earlier, we used the camera for video and image capture.
In 2014 google introduce Camera2 API with lollipop version (API Version 21). I would like to suggest you must use Camera API 2 if not have version constraint. Camera2 API is not supported below 21 API.
Camera2 device model takes input request to capture a single frame and a single image as per user. Each request is processed in order, multiple requests can process at a time.
