我正在使用 Phonegap 和 jQuery mobile 开发混合移动应用程序。我的应用程序在不添加 cordova.js 的情况下工作正常，但是当我添加 cordova.js 时，应用程序显示一些错误并崩溃。
我想在我的代码中添加 Phonegap 后退按钮事件，但它也不起作用，我希望 cordova.js 问题可能是问题所在。我使用的是 Cordova 2.4.0。
这是我的 logcat 和我的代码:

最佳答案
您的 AndroidManifest 文件中是否有“android.permission.ACCESS_NETWORK_STATE”？ Logcat 说你没有它，所以添加它。
