Constants

CAMERA_DISABLED

Added in API level 21
public static final int CAMERA_DISABLED

The camera is disabled due to a device policy, and cannot be opened.

Constant Value: 1 (0x00000001)

CAMERA_DISCONNECTED

Added in API level 21
public static final int CAMERA_DISCONNECTED

The camera device is removable and has been disconnected from the Android device, or the camera id used with CameraManager.openCamera(String, StateCallback, Handler) is no longer valid, or the camera service has shut down the connection due to a higher-priority access request for the camera device.
