如何将"com.unity3d.player.UnityPlayer“导入我的安卓库？

Question

我在将UnityPlayer依赖项输入到我的Android插件中时遇到了问题。

​

​

我只是想不出向插件添加依赖项的正确方法。

在我尝试将一个classes.jar文件添加到我的libs目录中之前，这个目录包含了所有的UnityPlayer代码，这使我能够在没有intellisense错误的情况下编写代码，但是当我构建和运行时，我得到了大量的输出。

CommandInvokationFailure: Gradle build failed.

我看到的大多是重复的错误，所以我猜我已经在我的Android项目中拥有了classes.jar中的所有内容。我从一个从Unitor.com导出的项目中构建了这个项目，并在Android中打开它，然后制作了"coffeeplugin"模块。

当我尝试在Gradle构建脚本中添加com.unity3d.player.UnityPlayer时，Android在同步Gradle时告诉我它是一个无效的字符串。

​

​

我知道它想要:SomeTag，我猜，但我不知道该放什么。统一文献并没有真正深入到这一部分(至少从我能够找到的文档和博客中)。

Answer 1

我准确地知道了这些AAR文件中包含了什么，我已经导入到了Unity中。我一直在做正确的事情，将classes.jar从Unity中包含到我的plugin/libs中。问题是，通过在Android中使用classes.jar在libs中构建插件，最终的AAR输出中包含了classes.jar，这在统一方面是多余的，因为团结已经有了这些数据，因此出现了重复的类错误。

修复是打开AAR是一些存档编辑器(7-zip或winrar)，并且只提取其中的clases.jar，并只将其导入到Unity中。

​

​

我很惊讶在这个过程中没有更多的官方文件。

而且，这个修复意味着没有必要对Gradle构建脚本进行编辑，除非您想要自动化从中间构建到统一的复制过程。

Answer 2

将implementation更改为compileOnly for 'com.unity3d.player'。这允许在编译时使用统一播放器classes.jar，而不是在导致复制的运行时使用。

Answer 3

我所做的事情被改名为Unity classes.jar to clases.jar

​

​

并在Gradle文件中添加了以下内容

​

，如果这仍然给出错误，那么：Goto File>>Settings
