Question

请不要将其标记为重复项，因为我无法找到解决问题的任何方法。添加Firebase Firestore依赖项时出现上述错误，这是logcat的输出：

在添加Firestore依赖项之前，一切都很好，请减少我宝贵的开发时间，我已经尽力了，但是这次我似乎不走运，请帮助我。

Answer 1

如下更改您的Firebase依赖关系：

//Firebase dependencies
implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.firebaseui:firebase-ui-auth:2.1.0'
implementation 'com.google.firebase:firebase-ads:17.1.3'
implementation 'com.google.firebase:firebase-firestore:18.1.0'

下面是各个依赖项的链接：您可以在此处找到所有版本，并可以进行更新以满足您的需求：

Answer 2

更改Firebase依赖项

com.google.firebase:firebase-core:16.0.9
com.google.firebase:firebase-auth:17.0.0
