WebView调用JS代码的问题

[weixin_38330488]

本地代码

        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.setBackgroundColor(Color.argb(0, 0, 0, 0));
        mWebView.getSettings().setDefaultTextEncodingName("utf-8");
        mWebView.addJavascriptInterface(new JsInteration() , "jsObj");
        mWebView.loadUrl("http://api.meeyou.net/h5/#/about-us");
        mWebView.setWebViewClient(new WebViewClient());


           public class JsInteration {
        @JavascriptInterface
        public void toUser() {
            finish();
        }
    }

这是logcat:

貌似没人给出一个好的答案，说一下我遇到这个错误的场景，打开www.baidu.com，百度自动访问了另外一个url：baiduboxapp://utils?action=sendIntent&minver=7.4¶ms=%7B%22intent%22%3A%22intent%3A%23Intent%3Baction%3Dcom.baidu.searchbox.action.HOME%3Bpackage%3Dcom.baidu.searchbox%3BS.targetCommand%3D%257B%2522mode%2522%253A%25220%2522%252C%2522intent%2522%253A%2522intent%253A%2523Intent%253Baction%253Dcom.baidu.searchbox.action.HOME%253Bcategory%253Dandroid.intent.category.DEFAULT%253BS.extra_target_tab%253DFeed%253Bend%2522%252C%2522min_v%2522%253A%252216787968%2522%257D%3Bend%22%7D&needlog=1&logargs=%7B%22source%22%3A%221021206d%22%2C%22from%22%3A%22openbox%22%2C%22page%22%3A%22chrome%22%2C%22type%22%3A%22%22%2C%22value%22%3A%22%22%2C%22channel%22%3A%221021206r%22%2C%22extlog%22%3A%22%22%2C%22baiduId%22%3A%2215DF1754549B48B4E3CD0E3C570A34FE%3AFG%3D1%22%2C%22app_now%22%3A%22chrome_1537447239894_4313893467%22%2C%22yyb_pkg%22%3A%22com.baidu.searchbox%22%2C%22idmData%22%3A%7B%7D%2C%22matrix%22%3A%22main%22%7D 报错信息errorCode：10，description：不支持的协议。 啊，很明显，这是什么鬼协议，不是http也不是https，chromium当然不认识了。 呐，解决办法就是把自己APP中webview不支持的url过滤掉就行了。 public boolean shouldOverrideUrlLoading(WebView view, String url) 这个方法中如果不支持当前的url则返回true，true表示拦截url之后自己处理，自己不去加载它即可。
