Special Settings

Compatibility polyfills, bridges, and other specialized toggles. This card collects the specialized WebViewConfig options.

Where: the Special settings card in the Edit Common Config editor.

Polyfills & bridges

• Clipboard polyfill — enableClipboardPolyfill.
• Notification polyfill — Web Notification support (enableNotificationPolyfill).
• Orientation polyfill — enableOrientationPolyfill.
• Compat polyfills — a bundle of compatibility shims (enableCompatPolyfills).
• Native bridge — expose a native bridge with capability gates (enableNativeBridge, nativeBridgeCapabilities).
• Print bridge — intercept window.print() and PDF output to the Android print framework (enablePrintBridge).
• Media Session bridge — bridge web media to the system media notification and lock-screen controls, including Bluetooth headsets and Android Auto (enableMediaSession).
• Share bridge — enableShareBridge.
• Zoom polyfill — enableZoomPolyfill.

Media & content

• Media autoplay — with scope (mediaAutoplayEnabled, mediaAutoplayScope: video-only, …).
• Image repair — fix broken images (enableImageRepair).
• Scroll memory — remember scroll position (enableScrollMemory).
• Back-state preservation — enableBackStatePreservation.
• Blob download interception — with scope and size threshold (enableBlobDownloadInterception, blobInterceptThresholdMb).

JavaScript & windows

• JS can open windows — with policy (javaScriptCanOpenWindows, jsOpenWindowsPolicy).
• Prime user activation — synthesize a user gesture, with mode and timing (primeUserActivation, primeUserActivationMode, primeUserActivationTiming).
• Base64 deep links — decode base64 deep links, gesture-only or always (decodeBase64DeepLinks, decodeBase64Mode).

Security & misc

• Cross-origin isolation — enableCrossOriginIsolation.
• Anti-capture — block screen capture (antiCapture).
• Hide status bar in video fullscreen — force-hide the status bar while a web video plays in HTML5 fullscreen, restoring it on exit (hideStatusBarInVideoFullscreen, on by default). Overrides the Fullscreen Mode "show status bar in fullscreen" option while the video holds the screen.
• File access from file URLs — allowFileAccessFromFileURLs, allowUniversalAccessFromFileURLs.
• Error page — custom error page config (errorPageConfig).
• Performance optimization — performanceOptimization.
• PWA offline — offline cache strategy (pwaOfflineEnabled, pwaOfflineStrategy).
• Floating back button — showFloatingBackButton.
• Keyboard adjust mode — keyboardAdjustMode (resize, …). On Android 10 and below, the RESIZE mode uses the classic window-resize path (the window is not edge-to-edge), so the keyboard resizes content reliably.
• Fullscreen video orientation — how fullscreen video orients (fullscreenVideoOrientation), e.g. auto sensor landscape.
• Hide URL preview — hideUrlPreview.

Notes

• These are power-user toggles; most apps leave them at defaults.
• Defaults: the safe experience features default to ON for new apps — clipboard / orientation / compat polyfills, media session, share, zoom and print bridges, image repair, scroll memory, back-state preservation, blob interception, JS windows, user-activation priming, base64 deep links, private-network bridge, and the native bridge. Deliberately OFF: notification polyfill (it would prompt POST_NOTIFICATIONS on every export), geolocation, mixed content, third-party cookies, autoplay, and popup blocking.
