Phonegap 3.2.0“很遗憾，AppName已停止。” 关闭应用程序时的对话框

当我关闭应用程序时，出现一个对话框，提示“不幸的是，MyApp已停止。” 和一个确定按钮。通过关闭，我的意思是在第一个屏幕上按下“后退”按钮。该应用程序确实关闭正常，但几秒钟后出现此对话框。

我正在使用PhoneGap 3.2.0。在更新到3.xx之前，它并没有发生。我不确定这是什么原因之后的确切版本。

Eclipse中的LogCat会在发生这种情况时予以解决：

有任何想法吗？

到目前为止，我一直在使用navigator.app.exitApp（）;行。如果在按下后退按钮时检测到我在index.html页面上，则关闭应用程序。

相反，我尝试删除后退按钮侦听器，并在按下后退按钮时恢复默认行为。它仍然导致相同的问题。

以下是一些简短的代码段：

$(document).ready(function ()
{
    document.addEventListener("deviceready", onDeviceReady, false);
}

function onDeviceReady()
{
    document.addEventListener("backbutton", backButton, false);
});

function backButton()
{
    var currentLocation = window.location.href.substr(window.location.href.lastIndexOf("/")+1);
    switch (currentLocation) {
    case 'index.html':
    navigator.app.exitApp();
    break;
}

更新2014/01/13 16:00：不确定是否有帮助，但是我注意到，如果我从index.html中注释掉脚本src =“ cordova.js”，它不会给出任何错误。
