    So I'm working with Camerax, new to Android development, and I'm attempting to write an application that takes an image on a specific event, not button related, without having to pull up the camera application. I have it all working, but my MainActivity is overloaded. So to clean up the MainActivity.java file I decided to offload different aspects to other files. Such as normal OOP concept.

    So I created a CameraFuncs.java file. Which I setup a constructor that I passed an object of the MainActivity class so I can access all the UI objects.

    Code (Java):
    1. public class CameraFuncs
    2. {
    3.     MainActivity main;
    4.  
    5.     public CameraFuncs(MainActivity mainActivity)
    6.     {
    7.         main = mainActivity;
    8.   ...
    9.   ...
    10.   ...
    11.      }
    12. }
    my orientation listener works just fine. I have access to UI objects. Everything seems to be working just fine. Execpt when I attempt to bindtolifecycle(). It throws an error.

    Code (Java):
    1. Camera camera = cameraProvider.bindToLifecycle((LifecycleOwner) this, cameraSelector,
    2.                 main.imageCapture);
    I get the following error

    I'm not really understanding whats going on with bind to lifecycle. Can something clarify whats happening here, point me in the right direction?
