Android uses webview to initialize the game, which requires the injection interface. Example steps

// Sample Code
// 1. Create an interface class
    class AndroidInterface {
        @JavascriptInterface
        fun showToast(message: String) {
        // Handling calls from JS
        }
    }

// 2. Injection interface
    webView.addJavascriptInterface(AndroidInterface(), "Android")

// 3. Check after the page has loaded
    webView.setWebViewClient(object : WebViewClient() {
        override fun onPageFinished(view: WebView?, url: String?) {
            super.onPageFinished(view, url)
                
            // Check if an Android object exists
            webView.evaluateJavascript("typeof window.Android") { result ->
                Log.d("WebViewConsole", "Android object type: $result")
            // If "object" is returned, the injection is successful.
            }
        }
    })
