Java 使用Android和Libgdx构建时出现意外的顶级异常错误

我正在尝试构建我的libgdx应用程序的最新版本，但没有成功地找出这里出了什么问题。我查找了其他类似的错误，并尝试查看是否有任何错误修复了我的问题，但没有成功（基本上是尝试更改Java版本，卸载/重新安装eclipse并重新安装所有更新）。这个问题是在最近几天安卓SDK更新后才开始的（从周四开始就没有导出过应用程序，这是我唯一能想到的改变）。你们有什么想法可以帮助我吗？这是完整的堆栈跟踪

编辑：我还更改了Android SDK中的Proguard文件，如下所述：。那似乎没什么用。

好吧。通过查看正在解析的文件“com/badlogic/gdx/graphics/g2d/Batch.class”并假设问题与libgdx项目附带的库有关，我发现了这个问题。我创建了一个新的libgdx项目，并将所有文件从我的旧项目移到了新项目中。现在一切正常，项目构建正确。希望这对将来的人有所帮助
