```
    Measuring is basically controlled by layout params width and height. The basic semantics are: - MATCH_PARENT: CameraView should completely fill this dimension, even if this might mean not respecting the preview aspect ratio. - WRAP_CONTENT: CameraView should try to adapt this dimension to respect the preview aspect ratio. When both dimensions are MATCH_PARENT, CameraView will fill its parent no matter the preview. Thanks to what happens in CameraPreview, this acts like a CENTER CROP scale type. When both dimensions are WRAP_CONTENT, CameraView will take the biggest dimensions that fit the preview aspect ratio. This acts like a CENTER INSIDE scale type.

```
    Maps a Gesture to a certain gesture action. For example, you can assign zoom control to the pinch gesture by just calling: cameraView.mapGesture(Gesture.PINCH, GestureAction.ZOOM); Not all actions can be assigned to a certain gesture. For example, zoom control can't be assigned to the Gesture.TAP gesture. Look at Gesture to know more. This method returns false if they are not assignable.
    
    Parameters:
    
    gesture - which gesture to map
    
    action - which action should be assigned
    
    Returns:
    
    true if this action could be assigned to this gesture

    Parameters:
    
    cameraListener - a listener for events.

    Clears the list of FrameProcessor that have been registered to preview frames.
  - capturePicture
```
public void capturePicture()
```
    Asks the camera to capture an image of the current scene. This will trigger CameraListener.onPictureTaken(byte[]) if a listener was registered. Note that if sessionType is SessionType.VIDEO, this might fall back to captureSnapshot() (that is, we might capture a preview frame).
    
    See Also:
    
    captureSnapshot()
  - captureSnapshot
```
public void captureSnapshot()
```
    Asks the camera to capture a snapshot of the current preview. This eventually triggers CameraListener.onPictureTaken(byte[]) if a listener was registered. The difference with capturePicture() is that this capture is faster, so it might be better on slower cameras, though the result can be generally blurry or low quality.

    durationMillis - recording max duration
  - stopCapturingVideo
