Eclipse dalvik“Tween Engine”类的链接在android上失败但在桌面上运行

Question

我正在使用libGDX为Android和台式机创建游戏。对于过渡屏幕，我正在使用Universal Tween engine。桌面版本运行完美，但每当我尝试运行Android版本时，我都会得到Fatal Exception。 NoClassDefFound类的SpriteTween异常发生，但它存在并在我的桌面游戏中成功检测到。

LibGDX对这两个版本使用相同的基本代码。所以从技术上讲，如果桌面版本有效，那么Android版本也可以正常工作。

我已经从logCat中添加了更多条目，我想这一切都是由于SpriteTween的Link类失败而发生的。为什么这只发生在android？

Answer 1

我提到了这个问题here。事实证明，在我的android项目buildpath＆gt; order＆amp;导出android 4.0.3标记未选中。通过检查该框，我的问题得到了解决。

与提到的stuntmania一样，问题不在于补间引擎，而在于我的构建路径。 dalvik机器无法检测到适当的库，因此只有android版本在桌面版本运行完美时无效。
