这与Cordova文档中的情况完全相同：http://docs.phonegap.com/en/1.9.0/cordova_events_events.md.html#deviceready

其他一切都在工作，但这将成为一个真正的障碍，因为我在从本地存储读取数据时需要它。我该不该相信这些文件？

干杯，萨米语

加载主页似乎花费了太长时间。你应该提取这3个jQuery文件，并将它们打包到你的应用程序中，而不是远程加载它们。

其他一切都很好

使用

<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no, width=device-width">

而不是

<meta name="viewport" content="width=device-width, initial-scale=1">

以及从类似的清单文件中删除screenSize

android:configChanges="orientation|keyboardHidden">
