As hjpotter92 mentions, this is how Java handles generics. In this case, I would just suggest using anonymous classes as indicated in hjpotter92's link.

public class MyActivity extends FragmentActivity {
     private LoaderCallbacks<String> mLoaderCallbackString = new LoaderCallbacks<String>() {
           ...
     };

     private LoaderCallbacks<Integer> mLoaderCallbackInteger = new LoaderCallbacks<Integer>() {
           ...
     };
}

Then for each loader, you just pass the correct LoaderCallbacks object
