IMM_CUR_ROOT_VIEW

When an activity is destroyed, the corresponding ViewRootImpl instance is released and ready to be garbage collected. Some time after that, ViewRootImpl#W receives a windowfocusChanged() callback, which it normally delegates to ViewRootImpl which in turn calls InputMethodManager#onPreWindowFocus which clears InputMethodManager#mCurRootView.

Unfortunately, since the ViewRootImpl instance is garbage collectable it may be garbage collected before that happens. ViewRootImpl#W has a weak reference on ViewRootImpl, so that weak reference will then return null and the windowfocusChanged() callback will be ignored, leading to InputMethodManager#mCurRootView not being cleared.
