android - onReceivedHttpError : support for android version < 23 错误

Question

我正在开发一个加载 url 的解决方案。我需要获取 Http 错误，以便重新加载 url 以创建新 session 。

@Override
   public void onReceivedHttpError(WebView view, WebResourceRequest request, WebResourceResponse errorResponse) {
            super.onReceivedHttpError(view, request, errorResponse);
            Toast.makeText(getActivity(), "Unexpected error occurred.Reload page again.", Toast.LENGTH_SHORT).show();
            if(errorResponse.getStatusCode() == 401){
                customWebView.loadUrl(url);
            }
        }

但上面代码的问题在于它在 Marshmallow 中运行。任何人都可以建议我一个解决方案，我可以在 android 版本 < 23 以下出现错误吗？

Answer 1

onReceivedHttpError

void onReceivedHttpError (WebView view, 
                WebResourceRequest request, 
                WebResourceResponse errorResponse)

通知主机应用程序在加载资源时已从服务器收到 HTTP 错误。

Can any one suggest me a solution where I can get error below android version < 23

onReceivedHttpError 添加到 API 级别 23。所以它不会在 23 以下工作。

尝试

.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {
        }

        @Override
        public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {

        /*if(Build.VERSION.SDK_INT<23)
         {
            // You work
         }*/
        }

        @Override
        public void onReceivedHttpError(
                WebView view, WebResourceRequest request, WebResourceResponse errorResponse) {

        /*if(Build.VERSION.SDK_INT >= 23)
            {
                 // Your Work
            }*/
        }

        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler,
                                       SslError error) {
        }
    });

仅供引用

onReceivedError

This method was deprecated in API level 23. Use onReceivedError(WebView, WebResourceRequest, WebResourceError) instead.
