我尝试将我的应用程序所使用的facebook sdk升级到最新版本（5.1.1），这使我不知疲倦地将项目迁移到AndroidX。完成迁移并解决了一些问题之后，我现在遇到了构建问题Error: Program type already present: androidx.asynclayoutinflater.R
我一直在尝试使用this answer及其其他变体来解决我的问题，但是我发现很难找到哪些库正在使用androidx.asynclayoutinflater.R
当我放弃依赖时，我会得到这个

我也尝试过强制支持库版本，不确定它是否有用，还是我做错了，但是我在SO上的帖子中看到了建议
final SUPPORT_LIB_VER = '28.0.0'
configurations.all {
resolutionStrategy {
force "com.android.support:appcompat-v7:${SUPPORT_LIB_VER}"
force "com.android.support:support-v4:${SUPPORT_LIB_VER}"
}
}
我的gradle.properties中也有这个
android.enableJetifier=true
android.useAndroidX=true
有人知道一种简单的方法来查找使用此特定依赖项的内容的方法，以便我可以尝试解决重复项，或者只是知道是什么库引起了该重复项吗？
答案 0 :(得分：2)
对于此常见问题，我建议使用稍微不同的方法。最重要的是：从干净的石板开始！这意味着，依次选择“文件”->“使缓存无效/重新启动”，然后依次选择“构建”->“清理项目”和“构建”->“重建项目”。现在将所有依赖项更新为最新（尽管有时会引入蠕虫，因为可能会引入新问题）。这通常会为我解决。
我时不时地遇到这个问题，并且发现在分支之间切换时会发生这种情况，因为它们之间的依赖关系有所不同。因此，如果您要在服务分支（例如，维护生产代码）和功能分支（例如，引入新的依赖项，无论是名称还是只是版本）之间来回切换，就会遇到这种情况。 Android Studio在切换分支时清理（很多事情，尤其是清理）方面做得很差。它正在查看过时的缓存信息，并发现实际上并不存在的冲突。
我希望这会有所帮助！
答案 1 :(得分：0)
因此，经过几天的苦难，我终于找到了问题
我不得不改变
implementation 'com.segment.analytics.android.integrations:firebase:1.3.1'
到
implementation 'com.segment.analytics.android.integrations:firebase:1.3.1@aar'
fml
解决这个问题的最简单方法是找到一个干净的新android项目，并将所有来自主项目的依赖项放到那里，然后使用分而治之来查明具体是哪个库导致了该问题。找到一个随机的0级答案，该答案建议不加解释地将@aar放在最后，并且有效。
