应用程序在 Android 2.2 (Froyo) 中根本无法启动

Question

在最近的 Froyo 更新之前，我的应用程序一直运行良好。安装 Android 2.2 SDK 后，我可以毫无错误地编译我的代码。但是，当我运行它时，它只是强制关闭：

这是日志：

主要的启动类是 com.handyapps.easymoney.EasyMoney。我在 onCreate() 方法的开头放置了一个断点，但我发现它甚至没有到达那里。不知何故，该应用程序无法在 Android 2.2 中加载……但它适用于所有以前的 Android 版本。过去 2 天一直在寻找原因，但完全被难住了！！

Answer 1

我找到了解决方案！只需要将manifest中的应用标签中的android:name属性去掉就可以了...但是编译器应该已经给出警告或者错误了。

Answer 2

来自ClassCastException：

当程序尝试强制转换时抛出 一个对象到它所在的类型 不兼容。

我会检查代码并检查我正在做的演员表。
