VirtualKeyboard API (`overlaysContent=true` + `env(keyboard-inset-*)`)** | JS opt-out: no viewport resize, keyboard overlays, geometry via CSS env vars | Yes (no resize) — but only the Blink side; OS must also not resize | API since Chrome 94; BCD `webview_android: mirror` | Needs `adjustNothing`; then drive layout from `env(keyboard-inset-bottom)` | Medium | Medium (you own focus-scroll) | Medium (feature-detect + flag) | +| **C. `adjustNothing` + VisualViewport/JS-driven** | OS doesn't resize window; read `visualViewport`, set `--keyboard-height` | Yes — window doesn't resize | VisualViewport Chrome 61+; M139+ also resizes visual viewport | Replaces `adjustResize`; edge-to-edge plugin keeps sole inset ownership (no double-handling) | Medium | Medium (own scroll-into-view; pre-M139 may give no signal) | Easy (manifest one-liner) | +| **D. `WindowInsetsAnimationCompat` deferred insets (native)** | Native per-frame translation matched to IME curve | N/A for web reflow — animates the native view | Android 11+ (compat to 10) | Used WITH `adjustResize` | High | High (single WebView; fights web `--keyboard-height`) | Hard | +| **E.

C achieves the same smoothness in-web and is a +one-line manifest revert. + +**Explicitly rejected — re-including `@capacitor/keyboard` on Android.** Tempting +("we already use Capacitor"), but wrong: it was removed on purpose because it +registers an unused insets callback that crashes in `Keyboard$1.onEnd` on some +devices (`capacitor.config.ts:38-40`; cf. capacitor #8055, capacitor-keyboard +#28 on API 35). Its `resize: 'none'/'body'` modes *still* need a +`windowSoftInputMode` change, so it doesn't avoid the flip — it just stacks a +known-flaky native callback on top of it. The visualViewport backbone is +strictly less code. + +## Recommended target architecture + +The OS stops resizing the WebView window during the IME animation, and the app +drives keyboard-aware layout from a keyboard-inset signal — removing the +documented per-frame reflow while preserving the edge-to-edge plugin's sole +inset ownership (no double-handling) and the add-task-bar pinning. + +**Approach B+C, runtime-gated (see the TL;DR correction).** Because the support +matrix starts at Chrome 107 and visualViewport-under-`adjustNothing` only signals +on ~Chrome 139+, the VirtualKeyboard API (Chrome 94+) is the **required** height +source, not a contingency.

Keep it OFF any ancestor of the add-task bar and the CDK + overlay root (it can create a containing-block/scroll context that shifts fixed + children or clips overlays). +- **On-device check:** re-trace; if open/close is now acceptably smooth, **stop + here** — the higher-risk Phase 2 becomes unnecessary. + +### Phase 2 — Runtime-gated `adjustNothing` + VirtualKeyboard (only if Phase 1 is insufficient) +This is the real reflow fix, but a coupled native+web change that is **100% +on-device-gated** and must be built with a device in the loop. Because the +support matrix starts at Chrome 107 (< the ~139 that auto-resizes the visual +viewport under `adjustNothing`), the VirtualKeyboard API is the required signal +source, and the switch must be **runtime-gated so no-API WebViews keep +`adjustResize` unchanged**: +1. **New native plugin method** to set `windowSoftInputMode` at runtime + (`SOFT_INPUT_ADJUST_NOTHING`) on `CapacitorMainActivity`. The manifest stays + `adjustResize` (the fallback); only this call flips capable devices. +2. **Capability gate (web):** only when `'virtualKeyboard' in navigator` — set + `navigator.virtualKeyboard.overlaysContent = true`, call (1), and drive + `--keyboard-height` from the `geometrychange` `boundingRect`. Order matters: + `env(keyboard-inset-*)` / `boundingRect` read 0 until `overlaysContent` is set, + and never set `overlaysContent=true` while still on `adjustResize` (Blink and + the OS disagree → double-offset bar).
