Android：在webview中檢查互聯網連接

我試圖在每次啓動應用程序時在webview中測試互聯網連接。Android：在webview中檢查互聯網連接

我嘗試調整一個我找到的例子，但它崩潰了。不管我的連接信息的狀態返回我相同的結果

嘗試是這樣的：

ConnectivityManager connmgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); 
     if (connmgr != null){ 
      NetworkInfo[] netInfo = connmgr.getAllNetworkInfo(); 
      if (netInfo != null){ 
       for (int i = 0; i < netInfo.length; i++){ 
        if (netInfo[i].getState() == NetworkInfo.State.CONNECTED){ 
         // you are connected 
        } 
       } 
      } 
     }
