How can I call OnActivityResult inside Fragment and how it work?

I want to know is it possible on onActivityResult()to use inside Fragment and if yes then how it works please explain with example.

You would call:

startActivityForResult(i, 1);

and then:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
   //super.onActivityResult(requestCode, resultCode, data); comment this unless you want to pass your result to the activity.
}

Use this code in the activity.

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    Fragment fragment = (Fragment) getSupportFragmentManager().findFragmentByTag(childTag);
    if (fragment != null) {
        fragment.onActivityResult(requestCode, resultCode, intent);
    }
}

Definitely it will work, It will work same like in activities. You have call startActivityForResult(intent, requestCode); and normally get result in

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
}

Yes you can use OnActivityResult inside Fragment.like this

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
// perform your action here
}

now you call onActivityResult like this

getActivity().startActivityForResult().

EDIT

The Above answer is old

check here the updated answer https://stackoverflow.com/a/17085889/7666442

if you call startActivityForResult() in fragment , result is delivered to parent activity.

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);//will deliver result to desired fragment.
}
