Question

我有一个使用WebView并加载页面的Android应用程序。此应用程序适用于运行API 16或更高版本的Android设备。

Android WebView代码：

String URL = "https://sandbox.napas.com.vn/gateway/message";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_web_view);

    webview = (WebView) findViewById(R.id.webview);

    webview.getSettings().setJavaScriptEnabled(true);
    webview.getSettings().setAllowFileAccess(true);
    webview.getSettings().setPluginState(PluginState.ON);
    webview.getSettings().setDomStorageEnabled(true);
    webview.getSettings().setAllowContentAccess(true);
    webview.getSettings().setAllowFileAccessFromFileURLs(true);
    webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

    webview.setWebChromeClient(new MyWebChromeClient());
    webview.loadUrl(URL);

    webview.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            view.loadUrl(url);
            return true;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
        }
    });
}

但是webview加载页面为空并且有日志：

请帮我修复此错误。感谢

我通过处理ssl Error找到了类似问题的解决方案。基本覆盖onReceivedSslError对象中的函数Webviewclient并设置handler.proceed()，删除了问题。

      WebViewClient webClient = new WebViewClient() {
            // Override page so it's load on my view only
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap facIcon) {

                mLayoutProgress.setVisibility(View.VISIBLE);

            }

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

            @Override
            public void onPageFinished(WebView view, String url) {

                mLayoutProgress.setVisibility(View.GONE);
            }
        };

我遇到了同样的问题＆amp;我关注了@DRY Believer的答案，但当我将应用程序上传到google Play时，他们拒绝了该应用程序并说你的应用程序正在使用WebViewClient.onReceivedSslError的不安全实现

相反，我找到了一种在服务器上正确安装我的SSL证书的方法，并修复了问题
