Just use interfaces. Pass to your non-activity class as listeners. — Harikumar Alangode, May 15 '18 at 06:34

u can do a callback on FragmentA and in DownloadFile to invoke it!

I tried, but can not do that, because we on FragmentA can not get data when we turn on setResult – Le Thanh Tan May 15 '18 at 03:58
u use the startActivityForResult or getActivity().startActivityForResult? – Fang May 15 '18 at 04:01
yes, but how to setResult to FragmentA which can get data. I need get data on FragmentA when startActivityForResult on non activity class. – Le Thanh Tan May 15 '18 at 06:36

onActivityResult() is a method in the class Activity. Therefore if you're not extending Activity, you can't override it

You need an Activity on order to receive the result of the action. If it is just for reuse and organisation then just call your other class from your Activity?

public class DownloadFile {
    public static void loadFiles(int requestCode, int resultCode, Intent data){
        ...
    }
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
   DownloadFile.loadFiles(requestCode,resultCode,data);
    ...
}

Yes, I tried it, but it's not possible, as on non activity class can not call setResult or any thing about ActivityResult — Le Thanh Tan, May 15 '18 at 06:37
