Illegal state exception in onActivityResult

Question

I've got this code in a fragment:

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent resultData) {
        if (requestCode == READ_REQUEST && resultCode == Activity.RESULT_OK) {
            Uri uri;
            if (resultData != null) {
                uri = resultData.getData();
                getChildFragmentManager().beginTransaction().add(new MyFragment(), TAG).commit();
            }
        }
    }

However there is crash with IllegalStateException. The activity can't create/restore transactions after onSaveInstanceState(). What is the correct method to start a fragment from another one in onActivityResult()?

Logcat:

Can you add the logcat, please? – OneCricketeer Mar 17 '17 at 17:54 — OneCricketeer, Mar 17 '17 at 17:54
And did you try using `beginTransaction().replace` instead? – OneCricketeer Mar 17 '17 at 17:55 — OneCricketeer, Mar 17 '17 at 17:55
@cricket_007 I don't want to replace the fragment – greywolf82 Mar 17 '17 at 17:57 — greywolf82, Mar 17 '17 at 17:57

You can use commitAllowingStateLoss

From the Documentation:

Like commit() but allows the commit to be executed after an activity's state is saved. This is dangerous because the commit can be lost if the activity needs to later be restored from its state, so this should only be used for cases where it is okay for the UI state to change unexpectedly on the user.

try using this:

getChildFragmentManager().beginTransaction().add(new MyFragment(), TAG).commitAllowingStateLoss();
