不幸的是，在使用cordova和jquery mobile开发android应用程序时，该应用程序已经停止

我不确定是什么原因导致运行不正常，当我在android模拟器中运行应用程序时，它显示错误“不幸的是，应用程序已停止”

感谢您的帮助。 我的logCat错误如下所示

它似乎缺少名为MainActivity的类。正确检查java类名和包名

似乎缺少名为MainActivity的类。正确检查java类名和包名

对于那些面临相同问题的人，我将发布解决方案

问题:

在Eclipse中创建了一个新的Android项目之后，我在构建路径中包括了cordova jar，并在Assets/www文件夹中添加了我的html页面，并在MainActivity.java文件中做了相应的更改。但在Android Emulator中运行应用程序时，它显示了一个错误“不幸的是HelloWorldCordova应用程序意外停止”

解决方案：请阅读我的要点以找到解决方案

MainActivity是在包

com.example.parkingtracker

中声明的公共类吗？是。它被声明并显示在下面公共类MainActivity扩展DroidGap{@Override public void onCreate（Bundle savedInstanceState）{super.onCreate（savedInstanceState）；//在config.xml System.out.println（config.getStartUrl（））中设置；super.loadUrl（config.getStartUrl（））；//super.loadUrl（“file:///android_asset/www/index.html“”}}请编辑您的问题，而不要在注释中添加太多代码。这是非常不可读的…MainActivity是在包
