I am trying to replace fragment in onActivityResult() but it always gives me error of java.lang.illegalStateException.
Caused by: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

Here is my onActivityResult code
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Fragment fragment = new VirtualListFragment();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame_container, fragment).commit();
}
Finally found the solution, fragment can not be swapped or replaced in onActivityResult()
We need to put this code in Handler or in OnResume()
Solution :
private boolean change_fragment=false;
OnActivityResult() Code
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
change_fragment=true;
}
OnResume() code
@Override
public void onResume() {
super.onResume();
if(change_fragment)
{
change_fragment=false;
Fragment fragment = new VirtualListFragment();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame_container, fragment).commit();
}
}
Answer：
The answer to this question is that you should not call commit on a fragment transaction before an activity loads it’s savedInstanceState or after it saves it’s savedInstanceState.
One of the existing answers for this question mentions Activity#onResume() as the place to commit the fragment transaction however Activity#onPostResume() would be a better option since it is called when the instance state of the activity is guaranteed to be restored.
A good explanation of what is happening and why it happens is provided in this blog post: http://www.androiddesignpatterns.com/2013/08/fragment-transaction-commit-state-loss.html

Have you tried this one? hope this one helps
You need to get a fragment manager from your main activity.
Try below snippet:-
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 1){
if(resultCode == Activity.RESULT_OK){
android.support.v4.app.FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
android.support.v4.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.container, new DemoFragment(), "fsdf").commit();
}
}
}
