App Resumed Callback

When your app is resumed from the background, the JavaScript function median_app_resumed() - if defined on the current page - will automatically be invoked. You can use this function to trigger background data refreshes, update page content, or perform a full page reload using window.location.reload().

📘

Note

On Android, median_app_resumed() is also triggered after any native permission prompt.

You can define median_app_resumed() directly on your web page or within your Custom JavaScript configuration.

Native Auto-Reload Plugin for Kiosk and Signage Apps

For Android apps used in kiosk or digital signage environments, we offer a custom native plugin that reloads app content at predefined intervals - bypassing JavaScript entirely. This ensures consistent and reliable refresh behavior, even in edge cases.

Contact our team to learn more about implementing this native solution.
