    onSizeChangedListener -
  - setOnActivityFlipListener
```
@UiThread
public final void setOnActivityFlipListener(OnActivityFlipListener onActivityFlipListener)
```
    Sets the listener that will be notified when activity flip event occurs.
    
    Parameters:
    
    onActivityFlipListener - Activity flip listener
  - setVideoResolutionPreset
```
@UiThread
public final void setVideoResolutionPreset(VideoResolutionPreset preset)
```
    Parameters:
    
    preset - Sets the preset that will be used for choosing camera video resolution.
  - setForceUseLegacyCamera
```
@UiThread
public final void setForceUseLegacyCamera(boolean useLegacyCamera)
```
    With this method you can request using legacy Camera API even on devices that natively support new Camera2 API. Set this to true only if you have problems with camera management on Lollipop and newer devices. Using legacy camera API is less efficient than new Camera2 API.
    
    Parameters:
    
    useLegacyCamera - If set to true, legacy Camera API will be used even on devices that support new Camera2 API.
  - setRequestAutofocusOnShakingStopInContinousAutofocusMode
```
@UiThread
public final void setRequestAutofocusOnShakingStopInContinousAutofocusMode(boolean requestAutofocusOnShakingStopInContinousAutofocusMode)
```
    If device supports continous autofocus mode, enabling this feature will request normal autofocus every time device shaking stops. By default, this is off, as is expected from device which supports continous autofocus to do this automatically. However, some devices do not meet that expectation so this tweak can be used to force autofocus after device has stopped moving.
    
    Parameters:
    
    requestAutofocusOnShakingStopInContinousAutofocusMode - will autofocus be requested each time device shaking stops.
  - setPhotoMode
```
@UiThread
public final void setPhotoMode(boolean photoMode)
```
    Parameters:
    
    photoMode - If set to true, Photo camera manager will be used instead of Video camera manager. Thus, user will have to take the picture before it goes to recognition. Default is false.
  - setOptimizeCameraForNearScan
```
@UiThread
public final void setOptimizeCameraForNearScan(boolean nearScan)
```
    Parameters:
    
    nearScan - Flag which indicates camera parameters should be optimized for near object scanning. When camera parameters are optimized for near object scanning, macro focus mode will be preferred over autofocus mode. Thus, camera will have easier time focusing on to near objects, but might have harder time focusing on far objects. If you expect that most of your scans will be performed by holding the device very near the object, turn on that parameter. By default, this parameter is set to false.
  - setUseTextureViewForCameraDisplay
```
@UiThread
public final void setUseTextureViewForCameraDisplay(boolean forceTextureView)
```
    In order to display camera preview, camera view must use one of two android's view's that are capable of displaying camera preview video stream. When using Camera2 API on Lollipop devices that support it, TextureView will always be used, regardless of this setting, however if legacy camera API is used, SurfaceView will be preferred because it is faster. Sometimes, when you create complex UI on top of camera screen, animations or UI may render incorrectly on some devices when using SurfaceView for displaying camera preview. In that case, you can call this method with parameter 'true' which will ensure TextureView to be used for displaying camera preview rather than SurfaceView. TextureView is slower, but is more UI friendly so it allows creation of more complex UI on top of camera preview. Please note that TextureView requires hardware acceleration to be enabled in your app and on the device. TextureView requires API level 14 (on older API levels, this setting will be ignored and SurfaceView will be used).
    
    Parameters:
    
    forceTextureView - Whether TextureView should be used even for legacy camera API.
  - getCameraEventsListener
```
public CameraEventsListener getCameraEventsListener()

```
public int getHostScreenOrientation()
```
    Returns the host's screen orientation as detected internally. Possible return codes are ActivityInfo.SCREEN_ORIENTATION_PORTRAIT, ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT, ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE and ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE
    
    Returns:
    
    the host's screen orientation
  - getVisiblePart
```
public android.graphics.RectF getVisiblePart()

If autofocus is required and device does not support autofocus, error will be raised and application will not start. If autofocus is not required, application will work even on devices without autofocus.
    
    Returns:
    
    True if autofocus is required, otherwise false.
  - onActivityFlip
```
protected abstract void onActivityFlip()
```
    Called when activity is flipped - this event is not raised by OS so we have custom detection of that state.

```
@UiThread
public void setOrientationAllowedListener(OrientationAllowedListener orientationAllowedListener)
```
    Sets the listener that will be asked if device orientation is allowed prior rotating rotatable view and native recognizer to that orientation. If you do not set this listener, recognition will be performed only in orientation defined by current activity's orientation.

    Sets the orientation listener that will receive orientation change events that are already reported to BaseCameraView. Orientation change events are independent of host activity's orientation settings.
