Answer 1

When you create the AsyncTask, you can add a new constructor to it, and pass in a reference to the Activity:

AsyncTask myTask = new MyTask(this);

And then from the onPostExecute() method in the AsyncTask you can call the method on the Activity.

public class MyTask extends AsyncTask
{
    public MyActivity activity;

    public MyTask(MyActivity a)
    {
        this.activity = a;
    }

    //  ......

    protected void onPostExecute(String result)
    {
        activity.myMethod();
    }
}
