startActivityForResult() vs getActivity().startActivityForResult() in Android Fragment

Question

What the differences between startActivityForResult() vs getActivity().startActivityForResult() in Android Fragment? And what is the behaviour differences in onActivityForResult() when called in Fragment?

Answer 1

startActivityForResult() must handle it from the fragment's onActivityForResult()

getActivity().startActivityForResult() must handle it from the activity's onActivityForResult()

Basically:

If you're on a fragment and you want to handle the result on the fragment, use onActivityForResult(), otherwise if you want to handle it from the activity of the fragment, use getActivity.startActivityForResult()

Answer 2

startActivityForResult from fragment call startActivityForResult of its container Activity. So for Fragment:-

Call startActivityForResult(Intent, int) from the fragment's containing Activity.

Whereas when you use it in fragment directly some certain changes can be made on request code.And you will get modified request code in onActivityresult(), Cause i have faced some problem with modified request code recently . You can have a look into This Thread.
