java.lang.IllegalStateException: Can't access ViewModels from detached fragment #529
Description
Hello,
This is a Question:
I am getting the said Exception when I upgraded all my Support Libraries to the latest one. 28.0.0
I am not using any Android Architectural Components in my app, but getting the this error.
It happens when I dynamically change Fragments in an Activity, using the FragmentTransactionManager
for Example this below code added in a FragmentA is causing the Issue
Bundle args = new Bundle(); args.putString("email",email); Fragment fragment = FragmentB.newInstance(args); FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.replace(R.id.container, fragment,"FragmentB"); fragmentTransaction.addToBackStack(null); fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE); fragmentTransaction.commitAllowingStateLoss();
this is working normally before I update to the latest Support Libraries
Can someone tell me what am I doing wrong/ am I supposed to change any code.
And a pic of Crash Logs:
