App Version Check API
Detect the installed app version from your web app and prompt users to update when needed.
Using this WebViewGold App Version Check API, your website/web app can retrieve the version of the Android app being used by your Android app user. This API is especially helpful if you want to notify users of an older version to update their app. Moreover, you can hide web app sections that require app features supported by a specific app version.
Use JavaScript to this kind of URL to read and alert the app version and app bundle number:
<script> window.location.href = "getappversion://"; alert(versionNumber); alert(bundleNumber); </script>
Alternatively, consider turning
AUTO_INJECT_VARIABLES to true in Config.java to automatically inject this (and other) values into JavaScript without needing to call a URL upfront.
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.
