No More □ — Mastering Emoji on Android
summary
Shows concrete fixes not vague promises: use EmojiCompat with dynamic font downloading (bundled font is ~7.4MB, download init delays ~150ms) or supply an emoji-one font as a custom Typeface; matching all 4,000+ emoji requires a generated regex and an emoji dictionary; naive string.length fails because a complex emoji is length 7 so Twitter fits ~40 of them into 280 chars, codePointCount gives 4, and a BreakIterator yields rendered graphemes; alternative build uses image spans or Typeface spans and the recommended APIs actually work with caveats.
