我有一个与PhoneGap/Cordova 2.5.0结合使用Android的应用程序。我有所有的HTML页面和javascript文件等本地；我不调用外部URL

在我尝试连接或断开蓝牙键盘（在我的例子中是肯辛顿键盘专家）之前，这一切都是完美无瑕的。在这种情况下，会发生以下情况：

页面将重新加载

webview等待大约20秒（我认为这是cordova默认超时？）

弹出一个标题为“应用程序错误”的警报，说明：

与服务器的连接不成功。（javascript:try{cordova.require（'cordova/channel'）.onDestroy.fire（）；}catch（e）{console.log（'exception firing destroy event from native'）；}；）

或者，适当缩进：

The connection to the server was unsuccessful.    
 (javascript: try {
     cordova.require('cordova/channel').onDestroy.fire();
 } catch (e) {
     console.log('exception firing destroy event from native');
 };)

我在互联网上搜索了一些解决方案，据说应该使用下面的HTML“欺骗”cordova

<!doctype html>
<html>
    <head>
        <title></title>
        <script>
            window.location='./actual.html';
        </script>
    <body>      
    </body>
</html>

很明显，我的问题是：为什么会发生这种情况，我该如何解决
