Question

我有一个使用Android与PhoneGap / Cordova 2.5.0结合使用的应用程序。我有所有HTML页面和javascript文件等本地;我不打电话给外部网址。

这一切都完美无瑕，直到我尝试连接或断开蓝牙键盘（在我的情况下是Kensington KeyFolio Expert）。在这种情况下，会发生这种情况：

页面重新加载
webview等待20秒（我认为这是Cordova的默认超时？）
弹出标题为Application Error的提醒，说：

与服务器的连接失败。（javascript：try {cordova.require（＆＃39; cordova / channel＆＃39;）。onDestroy.fire（）;} catch（e）{console.log（＆＃39;异常触发来自本地＆＃39; ）;};）

或者，正确缩进：

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下解决方案，据说有人应该“哄骗”。 cordova，使用下面的HTML。

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

但它无济于事。问题依然存在。其他主题说我应该使用loadUrlTimeoutValue来增加this.setIntegerProperty("loadUrlTimeoutValue", 60000);，但是：无效（加上我的脚本运行时间不超过2秒，因为它全部是本地的）。

这是我（dis）连接蓝牙键盘时发生的堆栈跟踪：

显然，我的问题是：为什么会发生这种情况，我该如何解决这个问题？

当（dis）连接蓝牙键盘时，Cordova崩溃
