What's New (?) in Android Text Over the Past Few Years
summary
Describes Android text features added between Android 9 and 13: API 29 adds custom font fallback allowing different fonts per script (e.g., Latin vs Japanese) with limits and family-style bundling; new text-shaping APIs (TextShaper, canvas.drawGlyph) expose glyph IDs and positions for per-glyph animation and debugging; emoji font updates use Play Services plus a platform font manager with signed secure installs; Android 13 introduces Japanese line-break rules and improved hyphenation modes (fast and full) and API 33 changes to fallback/spacing that require targeting SDK 33 to enable.
