Android - AsyncTask return value

I am looking to implement a generic type API Handler. I have created a class called ApiCall that extends the AsyncTask. The results are returned as a JSONArray.

I am new to Android and don't fully understand how to invoke a function in the Activity Class. I have seen several posts and blogs in regards to how to do this; however, most of them are either a private class withing the activity class or have some type of call back to the activity or fragment that provides a hard link back to the calling class.

I want to keep this class loosely coupled, to allow me to reuse this throughout the app.

Thank you for your insight.

You can pass a reference as a Weak reference. This will ensure that the class is loosely coupled to any UI elements.

     private  WeakReference<CallBack> callBack;
     //To assign a callBack reference to weak reference object
     callBack = new WeakReference<CallBack>(callBackReference);

     //To check if reference to callBack still available
     final CallBack callback = callBack.get();
     if(callback!= null){

      }
