The lesser-known world of Spans
summary
Explains that Android uses Spannable types (SpannableString, Spanned) so getString strips spans while getText can return a Spanned, details that Spannable.setSpan accepts any object and spans can overlap. Describes the four flags and that inclusive/exclusive flags control span growth with concrete editor and cursor examples, shows links use URLSpan, spellcheck and meta keys inject spans, demos: per-letter animations via ObjectAnimator, a shimmer via a custom span, a flatten-layout trick, and a small library BetterLinkMovementMethod fixes touch bounds and highlighting.
