You can trigger Java/Kotlin method execution from webview when you receive a notification like this

    mWebView.addJavascriptInterface(new MyJavaInterface(), "test");

    private class MyJavaInterface {
        @android.webkit.JavascriptInterface
        public String getGreeting() {
            return "Hello JavaScript!";
        }
}
