android - 如何将“com.unity3d.player.UnityPlayer”导入我的 Android 库？
问题描述
我在将UnityPlayer依赖项放入我的 Unity 的 Android 库插件时遇到问题。
我只是想不出将依赖项添加到我的插件的正确方法。
在我尝试将包含所有 UnityPlayer 代码的classes.jar文件添加到我的libs目录之前，这让我可以编写代码而不会出现智能感知错误，但是当我构建和运行时，我得到了如此庞大的输出。

我看到的大多是重复的错误，所以我猜我的classes.jarAndroid Studio 项目中已经包含了所有内容。我从 Unity 导出的项目构建项目并在 Android Studio 中打开它，然后制作"coffeeplugin"模块。
当我尝试添加com.unity3d.player.UnityPlayerGradle 构建脚本时，Android Studio 在我同步 Gradle 时告诉我它的字符串无效。
我知道它想要:SomeTag我猜，但我不知道该放什么。Unity 文档并没有真正涉及到这一部分（至少从我能找到的文档和博客中）。

解决方案
我准确地弄清楚了我一直导入到 Unity 的这些 AAR 文件中包含的内容。通过将classes.jarUnity 包含到我的plugin/libs. 问题是通过在 Android Studio 中构建我的插件 in classes.jar，libs被classes.jar包含在最终的 AAR 输出中，这在 Unity 方面是多余的，因为 Unity 已经有了这些数据，因此我得到了重复类错误。
修复方法是打开 AAR 是一些存档编辑器（7-zip 或 winrar）并仅提取其中的clases.jar内容并仅将其导入 Unity。
我很惊讶没有更多关于这个过程的官方文档。
此外，此修复意味着无需对 Gradle 构建脚本进行编辑，除非您想自动化从中间构建到 Unity 的复制过程。
