Constants
CAMERA_DISCONNECTED
static val CAMERA_DISCONNECTED: Int
The camera device is removable and has been disconnected from the Android device, or the camera id used with android.hardware.camera2.CameraManager#openCamera is no longer valid, or the camera service has shut down the connection due to a higher-priority access request for the camera device.
Value: 2
CAMERA_ERROR
static val CAMERA_ERROR: Int
The camera device is currently in the error state.
The camera has failed to open or has failed at a later time as a result of some non-user interaction. Refer to [CameraDevice.StateCallback.onError](/reference/kotlin/android/hardware/camera2/CameraDevice.StateCallback#onError%28android.hardware.camera2.CameraDevice,%20kotlin.Int%29) for the exact nature of the error.
No further calls to the camera will succeed. Clean up the camera with [CameraDevice.close](/reference/kotlin/android/hardware/camera2/CameraDevice#close%28%29) and try handling the error in order to successfully re-open the camera.
Value: 3
CAMERA_IN_USE
static val CAMERA_IN_USE: Int
The camera device is in use already.
Value: 4
MAX_CAMERAS_IN_USE
static val MAX_CAMERAS_IN_USE: Int
The system-wide limit for number of open cameras or camera resources has been reached, and more camera devices cannot be opened or torch mode cannot be turned on until previous instances are closed.
Value: 5
