AsyncTask + WeakReference - Android Studio Tutorial

In this video we will learn, how to use the AsyncTask class, which makes it easier to do operations on a background thread and publish the results on the UI/main thread, without having to manipulate threads and handlers ourselves.
For this we will subclass Asynctask, define 3 generic types for the params, the progress and the result and override 4 methods:
onPreExecute, where we do preparations on the UI thread, doInBackground where we do the heavy work on a background thread, onProgressUpdate where we publish the progress to the UI thread (for example to a ProgressBar), and onPostExecute where we get back the result from the background task.
In order to not leak memory by holding onto a strong reference to our MainActivity, we will make the AsyncTask static and keep a WeakReference to our Activity.
