fix(android): keep system bar icons light and fix bottom nav insets#273wizzomafizzo wants to merge 1 commit into
Conversation
Capacitor's SystemBars plugin re-applies its default style on every configuration change, which turned status bar icons dark in light system theme. Set SystemBars and StatusBar to DARK in config and at startup. Disable the Android nav bar contrast scrim and use the app background as the window background so the bottom nav shows behind the 3-button bar without a white strip or startup flash. Use env() safe area insets on Android, which SystemBars keeps accurate for the keyboard and rotation, removing the gap above the keyboard.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use the injected SystemBars variables as the primary Android values.
initSafeAreaInsets passes envInsets to the store for every Android WebView. capacitor.config.ts permits WebViews as old as 60, while Capacitor documents incorrect env() values below WebView 140. SystemBars injects --safe-area-inset-* by default. Change each envInsets entry to var(--safe-area-inset-*, env(...)) and document this fallback in docs/capacitor.md.

SystemBarsplugin re-applies its default style on every configuration change (rotation, fold, theme), which made status bar icons dark on the dark app background in light system theme.SystemBarsandStatusBarare now set toDARKincapacitor.config.tsand at startup inApp.tsx.#111928as the window background, so the bottom nav shows behind the 3-button navigation bar instead of a white strip, and cold start no longer flashes white bars.env(safe-area-inset-*)values, whichSystemBarskeeps accurate for the keyboard and rotation. This removes the gap above the keyboard and the stale bottom padding in landscape. iOS still usescapacitor-plugin-safe-area.App.tsxand safe-area changes can ship as a live update; the config and theme changes need a store build.Summary by CodeRabbit
