未在Phonegap應用程序中創建SQLite數據庫（Android）

Question

當我在Safari（桌面）或虛擬設備中測試我的應用程序時，可以看到數據庫按預期創建，但是如果我在物理設備上運行相同的應用程序（星系note選項卡）我可以看到/ data文件夾在DDMS文件資源管理器中是空的，我找不到數據庫。

我正在嘗試在onDeviceReady函數中創建數據庫，我可以看到它正在按預期發射。

我是否需要root訪問此設備？我檢查過，它沒有紮根？

這裏是我的config.xml：

<?xml version="1.0" encoding="UTF-8"?> 

<widget xmlns = "http://www.w3.org/ns/widgets" 
    xmlns:gap = "http://phonegap.com/ns/1.0" 
    id = "uk.co.epwin.ecobuild2013" 
    version = "0.0.1" 
    versionCode = "1"> 

<name>Ecobuild 2013</name>

你需要一個植根設備以擴大在文件瀏覽器中data文件夾。它看起來是空的，但它不是。

如果它在你的AVD上工作，它也應該在你的設備上工作，你只是無法訪問文件資源管理器上的數據庫文件。
