大家好！
我正在编写一个从Google电子表格（发布到网络）下载数据的Android应用程序，其中我已插入3行进行测试。我使用json格式的url作为电子表格的链接，以便我直接以json格式下载电子表格。当我在浏览器中输入网址时，我得到了json格式的电子表格：
/*O_o*/
google.visualization.Query.setResponse({"version":"0.6","reqId":"0","status":"ok","sig":"270757910","table":{"cols":[{"id":"A","label":"ID\n","type":"number","pattern":"General"},{"id":"B","label":"Title","type":"string"},{"id":"C","label":"Description","type":"string"},{"id":"D","label":"Picture","type":"string"},{"id":"E","label":"Date","type":"string"},{"id":"F","label":"Time","type":"string"},{"id":"G","label":"Author","type":"string"},{"id":"H","label":"Category","type":"string"}],"rows":[{"c":[{"v":1.0,"f":"1"},{"v":"title1"},{"v":"description1"},{"v":"picture1"},{"v":"date1"},{"v":"time1"},{"v":"author1"},{"v":"category1"}]},{"c":[{"v":2.0,"f":"2"},{"v":"title2"},{"v":"description2"},{"v":"picture2"},{"v":"date2"},{"v":"time2"},{"v":"author2"},{"v":"category2"}]},{"c":[{"v":3.0,"f":"3"},{"v":"title3"},{"v":"description3"},{"v":"picture3"},{"v":"date3"},{"v":"time3"},{"v":"author3"},{"v":"category3"}]}]}});
但是当我尝试使用此网址通过应用程序下载并记录结果时，我得到了这个：

我仍然没有完成代码，我只想看看我的应用以json格式正确下载电子表格。
我已经被困在这里超过3天，仍然无法找到问题。
我会感激我能得到的每一个帮助！
答案 0 :(得分：1)
我并不孤单！
我创建了一个从Google电子表格中提取数据的信息中心。几个小时前，我试图运行我的仪表板，收到一些错误，告诉我JSON格式有问题。我看一下＆＃39; / O_o /＆＃39;出现在所有文件的顶部。
这必须是谷歌手中的内部变化，无论是否有意，它可能会有望得到改变。
