我正在为桌面和安卓设备创建一个带有 libgdx 的应用程序。该应用程序在桌面（Windows）上运行良好，在冰淇淋三明治上也运行良好（在 Droid DNA、Nexus 7 和模拟的 Nexus One 上测试）。

但是，在 Droid X 或 Gingerbead 模拟器上，应用程序会立即崩溃。

什么可能导致应用程序在 Gingerbread 上崩溃，而不是在 ICS 上？

错误是：

我的android清单文件是：

您是否在使用 SDK 10 之后的任何 Android API com.ianmarkowitz.superfrenzy.MainActivity？MainActivity如果 Dalvik 链接器引用了不存在的类/方法，它将拒绝加载。
