我正在使用Android Studio尝试为Unity3d 5.3构建Android库.为此,我创建了一个Android库模块,我添加了classes.jar文件以与UnityPlayer一起使用,如下图所示:
然后,我生成了模块,我得到了'wrapper-debug.aar'文件,我把它放在'\ Assets\Plugins\Android'中.最后,当我构建时,我遇到以下错误:

我能理解的是,我正在添加已经添加的类.问题在于文件classes.jar.如果我把它取下来,插件工作正常但没有它,我不能在我的库中使用unityPlayer,这是我真正需要的东西.
另一种方法是做一个.jar库,但在这种情况下,我必须将res文件夹放在Unity的android插件文件夹中,但这是不推荐的.
还有另一种方法可以使用Android 5.x的android库吗？
非常感谢你如果您需要更多信息,请告诉我.
Unity在构建应用程序时会自动将其自己的类添加到项目中.如果将它们与库捆绑在一起,它们将被添加两次.
provided除了compile您当前使用的配置之外,Android的Gradle插件还定义了一个被调用的配置.它在某种意义上是不同的,它假设依赖项将在运行时出现在应用程序的类路径上,并且不包括构建库中的类.
要使用该provided特定JAR 的配置,请替换这两行
compile fileTree(include: ['*.jar'], dir: 'libs')
compile files('libs/classes.jar')
用这些
compile fileTree(dir: 'libs', include: ['*.jar'], exclude: ['classes.jar'])
provided files('libs/classes.jar')
这将使Gradle将放置在其中的每个JAR文件libs/视为与库捆绑在一起的依赖项,但classes.jar仅用于编译库.
请注意,如果您使用的是Android的摇篮插件3.0.0或更高版本,你应该使用implementation,而不是compile和compileOnly代替provided.这些配置已重命名:https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration#new_configurations.
