Best practices for using text in Android
summary
Android Q turns hyphenation off by default (hyphenation previously drove ~70% of TextView work) and adds tools to push text work off the UI thread: use PrecomputedText.getTextFuture / AppCompatTextView.setTextFuture with RecyclerView prefetch to move ~90% of text layout to background. Fonts: build multi-font fallbacks with Typeface.CustomFallbackBuilder up to 64 families, match system fonts with FontMatcher and list installed files with SystemFonts enumeration . For EditText prefer TextInputLayout, use IME flags like no personalized learning and force ASCII, and override focused rect to keep validation errors visible.
