WebView加载网页 提示错误 net::ERR_UNKNOW

      WebView加载一些其它地址的时候，往往会被重定向不是http、https开头，此处以简书为例，如果加载简书的文章url，会被重定向为：jianshu://notes/xxx，原先加载的url：https://www.jianshu.com/p/xxx，导致重写下面方法的出现上面异常
// 该方法已被废弃
@Override
public boolean shouldOverrideUrlLoading(WebView view, String redirectUrl) {
      if (redirectUrl.startsWith("http:") || redirectUrl.startsWith("https:")) {
            view.loadUrl(redirectUrl);
      return true;
      }
      return super.shouldOverrideUrlLoading(view, url);
}

@Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
      String redirectUrl = request.getUrl().toString();
      if (redirectUrl.startsWith("http:") || redirectUrl.startsWith("https:")) {
            view.loadUrl(redirectUrl);
            return true;
      }
      return super.shouldOverrideUrlLoading(view, request);
}

修复此问题只需要把重定向的操作拦截掉就可以，修复代码，链接开头非http、https的拦截掉

@Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
      String redirectUrl = request.getUrl().toString();
      if (!redirectUrl.startsWith("http:") || !redirectUrl.startsWith("https:")) {
            return true;
      }
      return super.shouldOverrideUrlLoading(view, request);
}
