如何在安卓系统中检测来自WebView的通知？

public class MyWebViewClient extends WebViewClient {
    @Override
    public WebResourceResponse shouldInterceptNotification(WebView view, WebResourceRequest request) {
        // 在此处理WebView接收到的通知
        return super.shouldInterceptNotification(view, request);
    }
}

WebView webView = new WebView(context);
webView.setWebViewClient(new MyWebViewClient());

@Override
public WebResourceResponse shouldInterceptNotification(WebView view, WebResourceRequest request) {
    String title = request.getTitle(); // 获取通知标题
    String content = request.getContent(); // 获取通知内容
    Bitmap icon = request.getIcon(); // 获取通知图标

    // 在此处理WebView接收到的通知

    return super.shouldInterceptNotification(view, request);
}
