Fragment getActivity is always returning null from Async Task

Question

I have called an AsyncTask inside my fragment. I was calling getActivity() from within doInBackground of that AsyncTask, but getActivity is returning null.

If I call getActivity outside from AsyncTask its working properly, but I need instance of activity inside my asyncTask itself.

Any help would be appreciated.. !!!

Answer 1

Pass Activity to AsyncTask method

new Demo().execute(getActivity());

public class Demo extends AsyncTask<Activity,Void,Void>{
    Activity activity=null;
    @Override
    protected Void doInBackground(Activity... params) {
        activity=params[0]; //get the activity instance 
        //Do your task

        return null;
    }
}
