Android: Alternatives to AsyncTask?

Question

for my app I made a framework for all network calls to an external API. I put everything in "Services" like: UserService, MessageService etc. So now when I want to call a network method I can't do this in the UI-Thread of my Activity so I made an AsyncTask and everything was just fine =)

But now I want something like giving the method to execute to the AsyncTask so I don't need to write an AsyncTask for every method of my network-framework. So instead of having something like this:

public class NetworkTask extends AsyncTask<UserService, Void, Void> {      @Override     protected Void doInBackground(UserService... params) {         UserService userService = params[0];         userService.getUser();         return null;     } } 

I want something more "abstract" so the AsyncTask doesn't need to know the "getUser" method? But I can't find any idea of how to do this... Maybe the AsyncTask is not good for this anyway?

Maybe you can use a third party library like Retrofit If you work with images I strongly suggest picasso
