closed. | | public static final int | CAMERA_DISABLEDThe camera is disabled due to a device policy, and cannot be opened. | | public static final int | CAMERA_DISCONNECTEDThe camera device is removable and has been disconnected from the Android
device, or the camera id used with {@link android.hardware.camera2.CameraManager#openCamera}
is no longer valid, or the camera service has shut down the connection due to a
higher-priority access request for the camera device. | | public static final int | CAMERA_ERRORThe camera device is currently in the error state.
