无法启动活动，并且应用程序崩溃了
我尝试添加一些依赖项，但无法合并 清单
C1它显示以下日志，我无法理解 我是否必须添加一些依赖项才能使其正常工作， 我可以在android设备上运行该应用，但是当我尝试启动 activityit崩溃了

该如何使该活动正常工作？ 这是依赖文件

答案 0 :(得分：0)
该错误可能是因为这些依赖项具有不同的版本号：
implementation 'com.google.firebase:firebase-auth:16.1.0'
implementation 'com.google.firebase:firebase-core:16.0.7'
implementation 'com.google.firebase:firebase-database:16.0.6'
implementation 'com.google.firebase:firebase-storage:16.0.5'
因此请尝试将其更改为以下内容：
implementation 'com.google.firebase:firebase-auth:16.1.0'
implementation 'com.google.firebase:firebase-core:16.1.0'
implementation 'com.google.firebase:firebase-database:16.1.0'
implementation 'com.google.firebase:firebase-storage:16.1.0'
还要在您的依赖项中添加implementation 'com.android.support:multidex:1.0.3'。
