可能重复：
XmlHttpRequest error: Origin null is not allowed by Access-Control-Allow-Origin

我正在开发在浏览器中运行良好的天气应用程序。但是，当我尝试在我的Android手机中部署它不能正常工作，它会抛出错误。 XML响应为空。请帮帮我。

Answer 1

您需要允许跨域调用http://www.webservicex.net

看这篇文章： Cordova 1.9.0 Ajax not retrieving

在您的res文件夹中编辑您的xml以包含以下行：

<access origin="http://www.webservicex.net*"/>

或者，如果其Phonegap-Build将该行添加到config.xml

ERROR --- Access-Control-Allow-Origin不允许使用Origin null
