程序类型已经存在:androidx.arch.core.internal.SafeIterableMap $ Entry生成签名的APK [英] Program type already present: androidx.arch.core.internal.SafeIterableMap$Entry while generating signed APK
问题描述
我有一个Android项目，该项目也必须包含一个Unity项目.在不导入Unity项目的情况下，我可以成功生成发布版本APK(带符号的APK).但是在包含Unity项目之后，我面临着这个问题:
I have an Android project which has to include a Unity project as well. Without importing the Unity project, I can successfully generated the release build APK (signed APK). But after including Unity project, I am facing this issue:
4个后续错误是:
Program type already present: androidx.arch.core.internal.SafeIterableMap$Entry
Caused by: com.android.tools.r8.CompilationFailedException: Compilation failed to complete
Caused by: com.android.tools.r8.utils.AbortException: Error: Program type already present: androidx.arch.core.internal.SafeIterableMap$Entry
Error: Program type already present: androidx.arch.core.internal.SafeIterableMap$Entry
我已采取步骤将unity项目纳入Android项目:
Steps I've taken to include the unity project into Android project:
- 导出Unity项目
- 将导出的项目构建为库
- 将.aar文件包含在本地android项目中
通过本机android应用级别，gradle是:

该问题是该问题的重复项 ，但原始问题没有答案，而且我没有足够的声誉来评论和询问该问题.唯一的区别是，在阅读完此问题后，我从Unity项目中删除了Firebase，并尝试生成签名的APK，但同样没有帮助，同样的错误.
This question is a duplicate of this question, but there is no answer to the original question and I don't have enough reputation to comment and ask about the issue. The only difference is, after reading this question, I removed Firebase from Unity project and tried to generate signed APK, that didn't help either, same error.
请帮助我解决此问题.预先感谢！
Please help me with this issue. Thanks in advance!
推荐答案
解决方案:
我设法通过从导出的unity项目的 libs 目录中删除androidx.*库来解决此问题.
Solution:
I managed to solve this issue by removing the androidx.* libraries from the libs directory of the exported unity project.
androidx.*库已经包含在本机android项目中.在将Unity项目作为库包含进来时，该库还包含所有这些androidx.*库，这些都是导致此问题的原因.
androidx.* libraries were already being included in the native android project. While including the Unity project as library, the library also had all these androidx.* libraries and these were causing this issue.
事实证明，在将Unity项目导出为本地Android项目时，Unity默认包含这些androidx.*库.仅当我们要从该项目中构建APK时才需要它们.但是，要从中构建库，就不需要这些androidx.*库.
As it turned out, while exporting a Unity project as native Android project, Unity by default includes these androidx.* libraries. They are only needed if we want to build an APK out of that project. But for building a library out of it, these androidx.* libraries are not required.
