android: is there Intent.Action of font setting changed?

Question

In android, when some of setting changed, the activity of app must reCreate, which may result in app crashed, like language or font setting; I know language setting's Intent.Action is ACTION_LOCALE_CHANGED, but can't find the font setting's Intent.Action; so the question is : what is font setting's Intent.Action in Android, if not, how to handle the case that font setting changed？

Answer 1

I got it;

android.intent.action.FONT_CONFIG_CHANGED

may be you guys can't find it in the Google source code!
