Android, can I put AsyncTask in a separate class and have a callback?

Question

I\'m just learning about AsyncTask and want to use it as a separate class, rather then a subclass.

For example,

class inetloader extends AsyncTask&l         


        

Answer 1

you can pass the activity instance to constructor and call activity function from there...
Like use interface :

public interface ResultUpdatable {

   public void setResult(Object obj);
   }

Implement this in the Activity and pass in the constructor of Async task and update the result from onPostExecute using setResult function.
