public void windowDismissed(IBinder appWindowToken) {
// Intentionally empty.
//
// It seems that some applications call this method via reflection to null clear the
// following fields that used to exist in InputMethodManager:
// * InputMethodManager#mCurRootView
// * InputMethodManager#mServedView
// * InputMethodManager#mNextServedView
// so that these objects can be garbage-collected when an Activity gets dismissed.
//
// It is indeed true that older versions of InputMethodManager had issues that prevented
// these fields from being null-cleared when it should have been, but the understanding of
// the engineering team is that all known issues have already been fixed as of Android 10.
//
// For older devices, developers can work around the object leaks by using
// androidx.activity.ComponentActivity.
// See https://issuetracker.google.com/u/1/issues/37122102 for details.
//
// If you believe InputMethodManager is leaking objects in API 24 or any later version,
// please file a bug at https://issuetracker.google.com/issues/new?component=192705.
