Best practices for text on Android
summary
Overview of concrete Android text practices: Minikin does shaping, line breaking and a system LRU word-measure cache of 5,000 items; hyphenation costs about 2.5× more CPU and depends on locale so use setTextLocale/LocaleSpan. Use premeasured text (PrecomputedText.create) off‑UI to cut measure cost ~90%, prefer SpannableStringBuilder for >250 spans, avoid XML autolink in RecyclerView (precompute Linkify/LinkifyCompat), use SpannableFactory to avoid copies, and use async Smart Linkify and the built‑in Magnifier for selection.
