请不要将其标记为重复，因为我未能找到解决问题的任何方法。我在添加 Firebase Firestore 依赖项时收到上述错误，这是 logcat 输出:

一切都很好，直到我添加 firestore 依赖项，拜托，我正在浪费宝贵的开发时间，我已经做了我能做的，但这次似乎我运气不好，请帮助我。
最佳答案
更改您的 Firebase 依赖项，如下所示:
//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'
Below are the links for respective dependencies: You can find all the versions there and can update which suits your needs:
https://mvnrepository.com/artifact/com.google.firebase/firebase-core https://mvnrepository.com/artifact/com.google.firebase/firebase-auth https://mvnrepository.com/artifact/com.firebaseui/firebase-ui-auth https://mvnrepository.com/artifact/com.google.firebase/firebase-ads https://mvnrepository.com/artifact/com.google.firebase/firebase-firestore
