我使用Android Studio 3.3 Canary 8.我创建了默认项目,然后我尝试运行该项目.但我见过以下stacktrace:

AGPBI:{"kind":"error","text":"程序类型已存在:androidx.core.graphics.PathSegment","sources":[{}],"tool":"D8"}任务:app :buildInfoGeneratorDebug FAILURE:构建失败并出现异常.*出了什么问题:任务执行失败':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.com.android.builder.dexing.DexArchiveMergerException:合并dex存档时出错:了解如何在https://developer.android.com/studio/build/dependencies#duplicate_classes中解决问题.程序类型已存在:androidx.core.graphics.PathSegment
