Android WebView 加载本地html跨域问题

参考地址：https://www.jianshu.com/p/833ac6734817

 try {//本地HTML里面有跨域的请求 原生webview需要设置之后才能实现跨域请求
            if (Build.VERSION.SDK_INT >= 16) {
                Class clazz = webView.getSettings().getClass();
                Method method = clazz.getMethod(
                        "setAllowUniversalAccessFromFileURLs", boolean.class);
                if (method != null) {
                    method.invoke(webView.getSettings(), true);
                }
            }
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
        webView.loadUrl("file:///android_asset/HtmlFileTT/index.html");
        webView.setWebViewClient(new WebViewClient(){
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
                return super.shouldOverrideUrlLoading(view, request);
            }
        });
