Sample error:
2021-03-05 00:12:59.453 13821-13821/com.cb.callrecorder E/FragmentManager: Fragment ReceivedCallFragment{23269ee} is not currently in the FragmentManager
Solution:
Change:
getSupportFragmentManager().putFragment(outState, RECEIVED_CALLS_FRAGMENT_KEY, mReceivedCallsFragment);
To :
if (mReceivedCallsFragment.isAdded())
getSupportFragmentManager().putFragment(outState, RECEIVED_CALLS_FRAGMENT_KEY, mReceivedCallsFragment);
