android webview ERR_UNKNOWN_URL_SCHEME

在android中webview请求网页时，有的网页跳转会报这个错，我之前代码是:

WebViewClient mWebviewclient = new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return super.shouldOverrideUrlLoading(view, url);
            }

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

            @Override
            public void onReceivedError(WebView view, int errorCode,
                                        String description, String failingUrl) {
                // TODO Auto-generated method stub
                super.onReceivedError(view, errorCode, description, failingUrl);
            }
        };
        webView.setWebViewClient(mWebviewclient);

网上查了帖子，说是将

webView.setWebViewClient(mWebviewclient);

改为

webView.setWebChromeClient(new WebChromeClient());

这样确实能解决问题，但是会导致其它问题，比如说我想在方法onReceivedSslError()或者onReceivedError()中做些处理，这时就很棘手，我的解决办法是，

WebViewClient mWebviewclient = new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return super.shouldOverrideUrlLoading(view, url);
            }

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

            @Override
            public void onReceivedError(WebView view, int errorCode,
                                        String description, String failingUrl) {
                // TODO Auto-generated method stub
                super.onReceivedError(view, errorCode, description, failingUrl);
            }
        };
        webView.setWebViewClient(mWebviewclient);

就是在 shouldOverrideUrlLoading()方法中，将view.loadUrl(url)方法去掉就好～
