Is there a way to reuse builder code for retrofit

I am using Retrofit and in every task I have to do something like this:

public class MyTask extends AsyncTask<String, String, String> {

    private void someMethod() {
        final RestAdapter restAdapter = new RestAdapter.Builder()
            .setServer("http://10.0.2.2:8080")
            .build();
        final MyTaskService apiManager = restAdapter.create(MyTaskService.class);
    }

    // ...

}

What is a good way to make this code DRY?
