Web视图显示加载URL后空白/白页在Android中使用WIFI时 [英] Web view shows blank/white page after loading url when using WIFI in Android

问题描述

我的WebView加载，我就加载它在这两个Android模拟器和设备（使用3G）。

My webview loads the url which I load on to it in both android emulator and device (using 3G).

当我打开同一网页带有WiFi它返回一个空白/白页。请帮助我在此。

When I load the same web page with wifi it returns a blank/white page. Pls help me on this.

    mWebView = (WebView) mRootView.findViewById(R.id.webView);

    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setRenderPriority(RenderPriority.HIGH);

    mWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);

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

            Log.d(TAG, "Finished loading URL: " + url);
        }

        @Override
        public void onReceivedError(WebView view, int errorCode,
                String description, String failingUrl) {

            Log.d("ON RECEIVE ERROR", failingUrl + " --- " + description);

        }       })
    mWebView.invalidate();
        mWebView.loadUrl(Url);

推荐答案

请添加

@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) 
{
handler.proceed(); // Ignore SSL certificate errors
}

在 setWebViewClient 。
