Pass Variable from Activity to AsynTask

Issue

I have a App with a Navigation Drawer and some fragments.

In my MainActivity i get the actual lat & long Location of the device.

On my first Fragment in the drawer i load in a AsyncTask some stuff out of my Database on my Webserver

For this request i need my Lat & Long variables from the MainActivity.

But how can i call a getLag() Method from MainActivity out of my AsyncTask or get my 2 variables?

I need the variables in the Methode updateJSONdata which is called in doInBackround()

public class LoadEvents extends AsyncTask<Void, Void, Boolean>{

        Activity activity;
        ListFragment LF;
        String TAG;

        public LoadEvents(Activity A, ListFragment lf, String TAG) {

            this.TAG = TAG;
            this.LF = lf;
            this.activity = A;
        }

        @Override
        protected void onPreExecute() {
            super.onPreExecute();


            MySwipeRefreshLayout srl = (MySwipeRefreshLayout) LF.getView().findViewById(R.id.srl);

            if(srl!=null){
                srl.setRefreshing(true);
            }

        }

        @Override
        protected Boolean doInBackground(Void... arg0) {

            updateJSONdata(TAG, activity);




            return null;

        }

Solution

Fragment onAttach()

MainActivity mainActivity;

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    mainActivity = (MainActivity) activity;             
}

Calling Activity method like this in your fragment

if (mainActivity != null)
    latLng = mainActivity.getLatLng(); //getLatLng() is a method defined in MainActivity
