public void onLowMemory()
```
    Called when the overall system is running low on memory, and actively running processes should trim their memory usage. https://developer.android.com/reference/android/app/Activity.html#onLowMemory()
  - surfaceCreated
```
public void surfaceCreated(SurfaceHolder surfaceHolder)
```
    Called immediately after the surface is first created. Implementations of this should start up whatever rendering code they desire. Note that only one thread can ever draw into a Surface, so you should not draw into the Surface here if your normal rendering will be in another thread.
    
    Parameters:
    
    surfaceHolder - The SurfaceHolder whose surface is being created.
  - surfaceChanged
```
public void surfaceChanged(SurfaceHolder holder,
                           int format,
                           int width,
                           int height)
```
    Called immediately after any structural changes (format or size) have been made to the surface. You should at this point update the imagery in the surface. This method is always called at least once, after surfaceCreated(SurfaceHolder).
    
    Parameters:
    
    holder - The SurfaceHolder whose surface has changed.
  - surfaceDestroyed
```
public void surfaceDestroyed(SurfaceHolder holder)
```
    Called immediately before a surface is being destroyed. After returning from this call, you should no longer try to access this surface. If you have a rendering thread that directly accesses the surface, you must ensure that thread is no longer touching the Surface before returning from this function.
    
    Parameters:
    
    holder - The SurfaceHolder whose surface is being destroyed.
  - onPause
```
public void onPause()
```
    This method can be called from the activity's onPause() method to store the state of the camera preview display before the application is sent to the background. The stored state can then be restored with a corresponding call to onResume() made from the activity's onResume() method.
  - onResume
```
public void onResume()
```
    This method can be used in conjunction with onPause() when called from the activity's onResume() method to restart the camera preview display based on the state it was in when the activity was paused and a corresponding call to onPause() was made.
  - getScreenSize
```
public WZSize getScreenSize()
```
    Returns the size of camera preview display
    
    Returns:
    
    The size of camera preview display, in pixels
  - registerFrameRenderer
```
public void registerFrameRenderer(WZRenderAPI.VideoFrameRenderer frameRenderer)
```
    Call to register an object instance implementing the WZRenderAPI.VideoFrameRenderer interface that can be used to render additional content, such as a logo, to the camera preview display
    
    Parameters:
    
    frameRenderer - An instance of a WZRenderAPI.VideoFrameRenderer implementation
  - unregisterFrameRenderer
```
public void unregisterFrameRenderer(WZRenderAPI.VideoFrameRenderer frameRenderer)
```
    Call to unregister a previously registered frame listener
    
    Parameters:
    
    frameRenderer - A previously registered instance of a WZRenderAPI.VideoFrameRenderer implementation
  - registerFrameListener
```
public void registerFrameListener(WZRenderAPI.VideoFrameListener frameListener)
```
    Call to register an object instance implementing the WZRenderAPI.VideoFrameListener interface that can be used to capture content from the camera preview display
    
    Parameters:
    
    frameListener - An instance of a WZRenderAPI.VideoFrameListener implementation
  - unregisterFrameListener
```
public void unregisterFrameListener(WZRenderAPI.VideoFrameListener frameListener)
```
    Call to unregister a previously registered frame listener
    
    Parameters:
    
    frameListener - A previously registered instance of a WZRenderAPI.VideoFrameListener implementation
