為Unity 3D 5.3構建Android庫時出錯 - Android Studio

Question

我正在使用Android Studio嘗試為Unity3d 5.3構建Android庫。 為此，我創建了一個Android庫模塊，我添加了classes.jar文件以與UnityPlayer一起使用，如下圖所示：

然后，我生成了模塊，我得到了'wrapper-debug.aar'文件，我把它放在'\\ Assets \\ Plugins \\ Android'中。 最后，當我構建時，我遇到以下錯誤：

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

我能理解的是，我正在添加已經添加的類。 問題在於文件classes.jar。 如果我把它取下來，插件工作正常但沒有它，我不能在我的庫中使用unityPlayer，這是我真正需要的東西。

另一種方法是做一個.jar庫，但在這種情況下，我必須將res文件夾放在Unity的android插件文件夾中，但這是不贊成的。

還有另一種方法可以使用Android 5.x的android庫嗎？

非常感謝你如果您需要更多信息，請告訴我。

Answer 1

Unity在構建應用程序時會自動將其自己的類添加到項目中。 如果將它們與庫捆綁在一起，它們將被添加兩次。

除了您當前使用的compile配置之外，Android的Gradle插件還定義了一個名為provided的配置。 它在某種意義上是不同的，它假設依賴項將在運行時出現在應用程序的類路徑上，並且不包括構建庫中的類。

要將provided配置與該特定JAR一起使用，請替換這兩行

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

compile files('libs/classes.jar')

用這些

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

provided files('libs/classes.jar')

這將使Gradle將libs/放置的每個JAR文件視為與庫捆綁在一起的依賴項，但classes.jar除外，它只用於編譯庫。

請注意，如果您使用的是Android Gradle插件3.0.0或更高版本 ，則應使用implementation而不是compile和compileOnly而不是provided 。 這些配置已重命名： https ： //developer.android.com/studio/build/gradle-plugin-3-0-0-migration#new_configurations 。
