Wysiwyg component to use inside my Android app?

My Android app lets users write HTML fragme开发者_JAVA百科nts.

WYSIWYG would be nice, but is there a WYSIWYG widget available for the Android UI?

Or do you know a JavaScript-based WYSIWYG component that works in an Android WebView?

Preferably usable in an Open Source app. Ideally Open Source itself.
