FragmentManager: No field with the name mListener is found in Animation class

Question

I got error when detaching (removing) a Fragment from my FragmentManager.

Detaching:

public void onFragmentDetached(String tag) {
        FragmentManager fragmentManager = getSupportFragmentManager();
        Fragment fragment = fragmentManager.findFragmentByTag(tag);
        if (fragment != null) {
            fragmentManager
                    .beginTransaction()
                    .disallowAddToBackStack()
                    .setCustomAnimations(R.anim.slide_left, R.anim.slide_right)
                    .remove(fragment)
                    .commitNow();
            unlockDrawer();
        }
}

Attaching:

getSupportFragmentManager()
                .beginTransaction()
                .disallowAddToBackStack()
                .setCustomAnimations(R.anim.slide_left, R.anim.slide_right)
                .replace(R.id.mainRootView, settingsFragment, SettingsFragment.TAG)
                .commit();

Here is my error:

I'm using SDK version 29, How can I fix this?

Answer 1

to simply put, just add below line to your build.gradle(:app), implementation "androidx.fragment:fragment:1.3.3"

Answer 2

This bug has been fixed in newer versions of androidx.fragment as mentioned in bug report someone made due to existing issue.
