我只是为我的 android 应用程序准备了小更新，但是当我尝试构建我的应用程序(在 Debug模式下)时，我遇到了这个奇怪的错误。如果更聪明的人可以查看此内容以找出可能出现的问题，那就太好了。我正在清理/重建/修复项目属性，但没有结果。我不知道发生了什么:(。也许这里的任何人都会发生类似的事情？ 如果这可以帮助我使用以下库:adMob(4.1.1)、openfeint 和 libgdx。

这里是构建日志:

最佳答案

您有两次包含相同的 jar 库。检查您的应用程序和所有引用的 Android 库，并确保您将所有 jar 包都包含一次。

如果没有帮助，请查看 http://tools.android.com/knownissues .具体看构建系统部分中描述的第一个问题。
