Summary

Constants
`int`	`CAMERA_DISABLED` The camera is disabled due to a device policy, and cannot be opened.

`int`	`CAMERA_IN_USE` The camera device is in use already.
`int`	`MAX_CAMERAS_IN_USE` 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.

Constants

CAMERA_DISABLED

Added in API level 21

int CAMERA_DISABLED

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

See also:

setCameraDisabled(android.content.ComponentName, boolean)

Constant Value: 1 (0x00000001)

CAMERA_DISCONNECTED

Added in API level 21

int CAMERA_DISCONNECTED

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from the Android device, or the camera id used with openCamera(String, CameraDevice.StateCallback, Handler) is no longer valid, or the camera service has shut down the connection due to a higher-priority access request for the camera device.

Constant Value: 2 (0x00000002)

CAMERA_ERROR

Added in API level 21

int CAMERA_ERROR

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 onError(CameraDevice, int) for the exact nature of the error.

No further calls to the camera will succeed. Clean up the camera with close() and try handling the error in order to successfully re-open the camera.

Constant Value: 3 (0x00000003)

CAMERA_IN_USE

Added in API level 23

int CAMERA_IN_USE

The camera device is in use already.

Constant Value: 4 (0x00000004)

MAX_CAMERAS_IN_USE

Added in API level 23

int MAX_CAMERAS_IN_USE

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.

Constant Value: 5 (0x00000005)
