当我在Safari（桌面）或虚拟设备中测试我的应用程序时，我可以看到数据库是按预期创建的，但如果我在物理设备上运行相同的应用程序（galaxy note选项卡），我可以看到/ data文件夹在DDMS文件资源管理器中为空，我找不到数据库。
我正在尝试在onDeviceReady函数中创建数据库，我可以看到它按预期触发。
我是否需要root访问此设备？我查了一下，它没有扎根？
这是我的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"

您需要有根设备才能展开文件资源管理器上的data文件夹。它看起来很空但不是。
如果它适用于您的avd，它也可以在您的设备上运行，您只是无法访问文件资源管理器上的数据库文件。
