Question

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，并且我已经获得了文件＆＃39; wrapper-debug.aar＆＃39;我把它放在＆＃39; \ Assets \ Plugins \ Android＆＃39; 。最后，当我构建时，我遇到了以下错误：

Error building Player: CommandInvokationFailure: Unable to convert classes   into dex format. See the Console for details.

我能理解的是，我正在添加已添加的类。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库但是在这种情况下，我必须将res文件夹放在Unity的android插件文件夹中，但这是不推荐使用的。

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。

在构建应用程序时，Unity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。

除了您当前使用的provided配置之外，Android的Gradle插件还定义了名为compile的配置。它在某种意义上是不同的，它假定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。

要将provided配置与该特定JAR一起使用，请替换这两行

compile fileTree(include: ['*.jar'], dir: 'libs')

compile files('libs/classes.jar')

与这些

compile fileTree(dir: 'libs', include: ['*.jar'], exclude: ['classes.jar'])

provided files('libs/classes.jar')

这将使Gradle将libs/中放置的每个JAR文件视为与您的库捆绑在一起的依赖项，但classes.jar除外，它仅用于编译您的库。

请注意，如果您使用的是Android Gradle插件3.0.0或更新版，则应使用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。
