Android WebView没有加载JavaScript文件,但Android浏览器加载它很好

我正在编写一个连接到后台网站的应用程序.后台站点包含大量JavaScript函数,至少是普通站点的100倍.不幸的是,它没有加载它们,并导致许多功能无法正常工作.所以我正在进行测试.我在我的服务器上放了一个页面,它加载了FireBugLite javascript文本.它有很多javascript,非常适合测试并查看Android WebView是否会加载它.WebView不加载任何内容,但浏览器会加载Firebug图标.究竟是什么会产生影响,为什么它可以在浏览器中运行而不是在我的WebView中运行？有什么建议.

更多的背景信息,为了在Droid(或除Windows之外的任何其他平台)上获得臭味的后台应用程序,我需要欺骗bakcoffice应用程序以相信访问该网站的是Internet Explorer.我通过修改WebView用户代理来完成此操作.

同样对于这个应用程序我已经缩小了我的登陆页面,所以我可以给你提供援助的来源.

后台应用程序是我的应用程序,在模拟器中运行.顶级应用程序是浏览器.您将看到浏览器具有firebug图标,并且可以激活firebug,但应用程序没有firebug图标.http://img413.imageshack.us/img413/9628/myapp.gif

我的应用程序在后台运行,因为您可以在右下角看不到Firebug.但是,浏览器(顶部的模拟器)具有相同的页面,但显示了firebug.我究竟做错了什么？我假设它没有足够的内存分配给应用程序,处理能力分配或物理内存的东西.我说不出来,我所知道的结果都很奇怪.

我从我的Android设备获得相同的东西,应用程序显示没有firebug但浏览器显示萤火虫.

我已经在Web浏览器上安装了JavaScript,问题是Web视图的行为与Web浏览器不同.
