Answer 1

这是一个有点乱码...你可以编辑你的问题，包装在一个代码块的东西，给它一些新行？刚开始时我看到很多PhoneGap的东西，也许你也可以用你的帖子标记你的帖子。反正很难破译这是怎么回事，这是显著错误等

哦，它就在那里，给我的时间...

那么它看起来像你试图迫使一些单一的JSONObject到JSONArray中......这似乎是个坏消息。你可以发布一些代码吗？

Answer 2

这条线：

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

貌似有连接到数据库中的错误。

这反过来又导致该错误行：

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 

因为这很可能应该是从数据库中抽取的所有值都为空值，因此，为什么你的应用程序失败。

的第一个错误告诉你到底是哪行代码失败：25467.

看看在你的项目中该行。

我想我可以帮忙，如果我能看到你的HTML代码。看起来你正在尝试做一个navigator.contacts.find（）并且它没有返回任何结果。我注意到的另一件事是你的错误回调试图执行“elert”，但可能应该是“警觉”。
