我正在使用Trigger IO框架处理HTML5应用程序。我在iPhone上测试它并且它在那里工作得很好。但问题在于Android。调试应用程序时出现以下错误。
CurrentLocation = LocationManager.GetLastKnownLocation(LocationManager.GpsProvider);
LocationManager.RequestLocationUpdates(LocationManager.GpsProvider, 0, 0, this);
if (CurrentLocation == null)//network provider
{
CurrentLocation = LocationManager.GetLastKnownLocation(LocationManager.NetworkProvider);
LocationManager.RequestLocationUpdates(LocationManager.NetworkProvider, 0, 0, this);
}
if (CurrentLocation == null)//passive provider
{
CurrentLocation = LocationManager.GetLastKnownLocation(LocationManager.PassiveProvider);
LocationManager.RequestLocationUpdates(LocationManager.PassiveProvider, 0, 0, this);
}
这适用于从html标头引用的每个资源文件。我的标题代码是：

这两个文件都存在于该位置，并且在iOS上运行良好。但问题在于Android / Chrome。任何解决方法？
修改
以下是index.html的标题：
Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME
注意：如果我删除了jquery.mobile-1.4.5.min.js文件，那么它将引用index.js
