Android開發錯誤，使用Eclipse

Question

即時通訊與我的項目有這個問題。我不知道該怎麼做。請幫幫我。這裏是應用程序的運行logcat中通過模擬器2.2

Answer 1

這是一個有點亂碼...你可以編輯你的問題，包裝在一個代碼塊的東西，給它一些新行？剛開始時我看到很多PhoneGap的東西，也許你也可以用你的帖子標記你的帖子。反正很難破譯這是怎麼回事，這是顯著錯誤等

哦，它就在那裏，給我的時間...

那麼它看起來像你試圖迫使一些單一的JSONObject到JSONArray中......這似乎是個壞消息。你可以發佈一些代碼嗎？

Answer 2

這條線：

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

貌似有連接到數據庫中的錯誤。

這反過來又導致該錯誤行：

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 

因爲這很可能應該是從數據庫中抽取的所有值都爲空值，因此，爲什麼你的應用程序失敗。

的第一個錯誤告訴你到底是哪行代碼失敗：25467.

看看在你的項目中該行。

Answer 3

我想我可以幫忙，如果我能看到你的HTML代碼。看起來你正在嘗試做一個navigator.contacts.find（）並且它沒有返回任何結果。我注意到的另一件事是你的錯誤回調試圖執行「elert」，但可能應該是「警覺」。
