Zepp OS Navigation & Lifecycle

Context: Device App (Mini Program). Watchfaces have no pages — see zepp-os-watchface. API_LEVEL: 2.0+. Prereq: registering pages in app.json — see zepp-os-fundamentals.

Overview

A Mini Program is App() + one or more Page() instances. You move between pages with @zos/router and hook behavior into the lifecycle. There is no virtual DOM — build() draws the UI imperatively (see zepp-os-ui).

Lifecycle order

App onCreate(params)   // init globalData; NO UI yet (page not loaded)
  → Page onInit(params)  // params from push/replace (a string)
    → Page build()        // draw widgets here
    → Page onDestroy()
App onDestroy()
