Question

@Override
protected String doInBackground(String... pa         


        

Answer 1

1. Get the context in the constructor like this:

   public GetDataTask(Context context) {}

2. Create an Interface with the method:

   void onDataRetrieved(String data);

3. Implement the Interface in the class from where you are creating the Task object (e.g. MainActivity)

4. Cast the Context to the Interface and call the onDataRetrieved Method
