Java 清单合并失败，出现多个错误：梯度同步问题

我是Android Studio的新手。我收到此错误：清单合并失败，出现多个错误，请参阅日志：

这是我的build.gradle（项目）

这是我的build.gradle（模块应用程序）

这是我的AndroidManifest.xml

我已经找到了解决办法，但没有一个有效。 以下是错误生成：

我不知道从哪里克服这些错误。请帮忙。提前感谢。：）

问题是什么？这可能与androidX迁移有关，因为您是最新的firebase库。问题是，当我运行时，它的合并失败，并出现多个错误。我无法迁移到androidX，因为它表明我的其他xml/java文件上的某些用法与usI共享失败的生成日志编辑了此帖子。添加一些失败的生成日志
