Question

请帮帮我

错误：任务 ':app:transformDexArchiveWithExternalLibsDexMergerForDebug' 执行失败。 java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: 无法合并 dex

我尝试清理和重建项目，但它仍然存在 我删除了 .gradle 文件夹但没有任何反应

这是我的 build.gradle

apply plugin: 'com.android.application'

试试这个

implementation 'com.google.android.gms:play-services-auth:11.4.2'
implementation 'com.google.android.gms:play-services-ads:11.4.2'
implementation 'com.google.firebase:firebase-appindexing:11.4.2'
implementation 'com.google.firebase:firebase-ads:11.4.2'
implementation 'com.google.firebase:firebase-storage:11.4.2'
implementation 'com.google.firebase:firebase-config:11.4.2'
implementation 'com.google.firebase:firebase-messaging:11.4.2'
implementation 'com.google.firebase:firebase-core:11.4.2'
implementation 'com.google.firebase:firebase-auth:11.4.2'
implementation 'com.google.firebase:firebase-database:11.4.2'
implementation 'com.firebaseui:firebase-ui-database:3.1.0'

或者这个

implementation 'com.google.android.gms:play-services-auth:11.8.0'
implementation 'com.google.android.gms:play-services-ads:11.8.0'
implementation 'com.google.firebase:firebase-appindexing:11.8.0'
implementation 'com.google.firebase:firebase-ads:11.8.0'
implementation 'com.google.firebase:firebase-storage:11.8.0'
implementation 'com.google.firebase:firebase-config:11.8.0'
implementation 'com.google.firebase:firebase-messaging:11.8.0'
implementation 'com.google.firebase:firebase-core:11.8.0'
implementation 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.firebaseui:firebase-ui-database:3.2.2'
