Description

添加tag Fragment fragment = LoginSelectIdentityFragment.newInstance(); Rigger.getRigger(fragment).setFragmentTag(LoginSelectIdentityFragment.class.getName()); Rigger.getRigger(puppet).startFragment(fragment); 查找tag Fragment fragment = Rigger.getRigger(this) .findFragmentByTag(LoginSelectIdentityFragment.class.getName()); 这时查找的fragment总是为null，然后我又Rigger.getRigger(puppet).startFragment(LoginSelectIdentityFragment)，结果就报错了。这是为什么啊？

Contributor guide

Research direction
Investigate the setFragmentTag and findFragmentByTag methods in Rigger. Trace how tags are stored and retrieved. Check if the fragment is properly attached to the FragmentManager before searching by tag. Also review startFragment to understand the error when starting an already managed fragment.
