在 Unity 中为 Android 构建 Google VR 项目，重新打包资源时失败
Building Google VR project for Android in Unity, fails when repackaging resources
我正在尝试为 Google Cardboard 构建一个 真正 的基本应用程序，但我无法通过构建。该应用程序没什么特别的，只有一个地形、一个球体、GvrMain 预制件和一个十字线。它在 Unity 播放器中运行良好。我在构建的中途收到此错误：
CommandInvokationFailure: Failed to re-package resources. See the Console for details.

这可能是由于您使用的 24.0.0 构建工具的错误所致。尝试从您的 SDK 管理器中删除它并重新启动 Unity。这是一个有类似问题的post。
我在这个帖子中采纳了 retrobullet 的建议解决了这个问题：
http://answers.unity3d.com/questions/653814/android-build-error-win-32-aaptexe-.html
首先，将 C:\Users\%username%\AppData\Local\Android\sdk\platforms 和 C:\Users\%username%\AppData\Local\Android\sdk\build-tools 的所有内容移动到备份位置。然后，打开 Unity 并构建项目。它应该检测到构建工具不存在并下载正确的版本。
