 Executor executor,
 int uid)
                                          throws CameraAccessException

Throws:

CameraAccessException

openCameraDeviceUserAsync

@Implementation(minSdk=25,
                maxSdk=27)
protected CameraDevice openCameraDeviceUserAsync(String cameraId,
 CameraDevice.StateCallback callback,
 Handler handler,
 int uid)
                                          throws CameraAccessException

Throws:

CameraAccessException

openCameraDeviceUserAsync

@Implementation(maxSdk=24)
protected CameraDevice openCameraDeviceUserAsync(String cameraId,
 CameraDevice.StateCallback callback,
 Handler handler)
                                          throws CameraAccessException

Enables CameraManager.openCamera(String, StateCallback, Handler) to open a CameraDevice.

If the provided cameraId exists, this will always post CameraDevice.StateCallback.onOpened(CameraDevice) to the provided Handler. Unlike on real Android, this will not check if the camera has been disabled by device policy and does not attempt to connect to the camera service, so CameraDevice.StateCallback.onError(CameraDevice, int) and CameraDevice.StateCallback.onDisconnected(CameraDevice) will not be triggered by CameraManager.openCamera(String, StateCallback, Handler).

Throws:

CameraAccessException

registerAvailabilityCallback

@Implementation
protected void registerAvailabilityCallback(CameraManager.AvailabilityCallback callback,
 Handler handler)

unregisterAvailabilityCallback

@Implementation
protected void unregisterAvailabilityCallback(CameraManager.AvailabilityCallback callback)

registerTorchCallback

@Implementation(minSdk=23)
protected void registerTorchCallback(CameraManager.TorchCallback callback,
 Handler handler)

unregisterTorchCallback

@Implementation(minSdk=23)
protected void unregisterTorchCallback(CameraManager.TorchCallback callback)

addCamera

public void addCamera(String cameraId,
 CameraCharacteristics characteristics)

Adds the given cameraId and characteristics to this shadow.

The result from getCameraIdList() will be in the order in which cameras were added.

Throws:

IllegalArgumentException - if there's already an existing camera with the given id.

removeCamera

public void removeCamera(String cameraId)

Removes the given cameraId and associated characteristics from this shadow.

Throws:

IllegalArgumentException - if there is not an existing camera with the given id.

getTorchMode

public boolean getTorchMode(String cameraId)

Returns what the supplied camera's torch is set to.

triggerDisconnect

public void triggerDisconnect()

Triggers a disconnect event, where any open camera will be disconnected (simulating the case where another app takes control of the camera).

updateCameraCallback

protected void updateCameraCallback(CameraDevice device,
 CameraDevice.StateCallback callback,
 @Nullable
 Handler handler,
 @Nullable
 Executor executor)

reset

@Resetter
public static void reset()
