java Android Libgx青蛙游戏崩溃：找不到类的com。伦格伯特。青蛙。青蛙游戏'

Question

我试图在这里运行教程：http://www.rengelbert.com/tutorial.php?id=175

这就是Frogger游戏，我导入了项目，Java版本运行得很好，但运行Android版本时，我遇到了崩溃。我对这件事还不太熟悉，正在寻求帮助

以下是我得到的：

所以我想这就是原因：12-20 17:32:01.725: E/dalvikvm(231): Could not find class 'com.rengelbert.froggergdx.FroggerGame', referenced from method com.rengelbert.froggergdx.FroggerGDX.onCreate

我在主题：libgdx game not working in 安卓 phones上找到了这条线索

在进入Java构建类并检查gdx之后。jar后端jar文件和FroggerDesktop文件，我仍然会崩溃

如果这些文件是依赖项，为什么在导入项目时不自动检查它们？我想在导入项目后，一切都应该正常工作

谢谢你的帮助
