下一个错误是什么意思：“程序类型已存在”

Question

当前在构建react-native项目时遇到问题构建后，我在控制台中遇到下一个错误：

  

任务：app：transformDexArchiveWithExternalLibsDexMergerForDebug失败   D8：程序类型已存在：android.support.v4.app.LoaderManager $ LoaderCallbacks

失败：构建失败，并出现异常。

  

  
• 出了什么问题：   任务'：app：transformDexArchiveWithExternalLibsDexMergerForDebug'的执行失败。   com.android.builder.dexing.DexArchiveMergerException：合并dex存档时出错
