Android开发错误，使用Eclipse

Question

我的项目遇到这个问题。我不知道该怎么办。请帮我。这是模拟器 2.2 运行的应用程序的 logcat

Answer 1

这有点乱码......你可以编辑你的问题，将内容包装在代码块中并给它一些换行符吗？乍一看，我看到了很多 PhoneGap 的东西，也许你也可以用它来标记你的帖子。不管怎样，很难破译发生了什么，这是一个重大错误，等等。

哦，就是这样……给我一点时间……

好吧，看起来你正试图将一些单个 JSONObject 强制到 JSONArray 中……这似乎是个坏消息。你能发布一些代码吗？

Answer 2

这一行：

02-23 07:48:39.503: I/Database(274): sqlite returned: error code = 14, msg = cannot open file at source line 25467

看起来连接数据库时出错。

这又会导致此错误行：

 02-23 07:48:40.154: E/Contact Query(274): Value {"birthday":null,"ims":null,"nickname":null,"rawId":null,"urls":null,"organizations":null,"emails":null,"phoneNumbers":null,"photos":null,"id":null,"name":{"middleName":null,"familyName":null,"formatted":"","givenName":"","honorificSuffix":null,"honorificPrefix":null},"categories":null,"addresses":null,"displayName":null,"note":null} at 0 of type org.json.JSONObject cannot be converted to JSONArray

因为可能应该从数据库中提取的所有值都是空值，因此您的应用程序失败了。

第一个错误准确地告诉您哪一行代码失败：25467。

查看项目中的该行。

我想如果我能看到您的 HTML 代码，我可以提供帮助。您似乎正在尝试执行 navigator.contacts.find() 并且它没有返回任何结果。我注意到的另一件事是您的错误回调正在尝试执行“elert”，但这可能应该是“alert”。
