Android Studio中的“接收失败”错误

Question

我已经在Webview中打开了本地html文件。网页中唯一的功能是JavaScript超时功能，该功能每10秒运行一次（但是我不确定这段代码是否可以在webview上运行，但这不是我的问题）。

function checkConnection(){
    try {
         if (navigator.onLine){
         //do something
         }
        else{
         //do something
        }
        }catch(err){}
    setTimeout(checkConnection,10000);
}

我在logcat中每秒收到很多错误。我不知道此错误是来自Webview还是其他原因？
