QR Code Scanner API
Open a native QR code scanner from your web app and process scan results via URL or JavaScript.
To trigger the QR code scanner within your WebView-based Android app, use the following HTML link format:
<a href="qrcode://">Scan QR Code</a>
Clicking this link will open the device’s camera to scan a QR code, and any URL encoded in the QR code will load automatically within the WebView.
Use Cases:
- Bridging print and digital content (e.g., scanning a QR code from a magazine to open a webpage).
- Quick access to promotions, product information, or events.
- Securely linking users to internal app resources or specific landing pages.
SDK-style implementation notes
Treat this feature as a native capability exposed to your web layer: keep your production website or PWA as the source of truth, then use the documented WebViewGold configuration flags, URL commands, and JavaScript bridge calls to opt in to native Android behavior only where it adds value. This approach keeps your codebase maintainable because the same web application can serve browsers, WebViewGold for Android, and the other WebViewGold platforms with minimal conditional logic.
For reliable results, prefer HTTPS endpoints, stable route names, explicit success/error states in your UI, and small JavaScript helper functions that wrap native calls. For example, a web app built with jQuery Mobile, Lovable, Base44, Bolt, WordPress, Bubble, a custom React/Vue/Angular stack, or static HTML can expose a single button or event handler that triggers the native WebViewGold API while still showing a graceful browser fallback.
- Recommended integration pattern: detect the app context, call the WebViewGold API, then update your web UI after the native callback or route change.
- Testing checklist: validate the feature on a real device or packaged build, verify permissions and store review text, and confirm that browser-only users still receive a useful fallback.
- SEO benefit: keep feature pages, route titles, and structured content indexable on your website while WebViewGold delivers the native app shell for Android users.
