Integrate SpeedOf.Me speed testing into your Android app using Kotlin and WebView. The API runs in a hidden WebView while your native UI displays the results.
Uses @JavascriptInterface for secure JavaScript-to-Kotlin communication.
The HTML page that loads in the hidden WebView, runs the speed test, and sends results back to Kotlin via window.Android.
Complete Kotlin Activity implementation with WebView setup, @JavascriptInterface bridge, and native UI for displaying results.
