Fonts, Emoji and Text Using Support Libraries
summary
Android Oreo plus Support Library v26+ brings concrete features and caveats for app text handling Fonts in XML lets you bundle or reference .ttf families and apply one theme line via ResourcesCompat.getFont, Downloadable Fonts uses the Google Play font provider (≈800 Google fonts) to save up to ~7 MB APK size and shares cached fonts but may require blocking fetch or preload and depends on Play Services, EmojiCompat with Noto Color Emoji enables API19+ fallback rendering, and TextView autosizing (API14+) does binary‑search sizing with min/max/step and needs AppCompat and careful layout constraints.
