“找不到 com.google.firebase:firebase-analytics”

Question

请我在通过添加 firebase 依赖项更改这些文件后发现运行我的应用程序的问题。非常感谢您的帮助。

我的应用程序最初可以运行，但是在将 firebase 依赖项添加到 Gradle 构建后，我得到了 构建失败异常。我已经阅读了 Stackoverflow 上提供的许多解决方案，但它们并没有解决我的问题。请在下面找到我的代码

\\I am facing an error running my application and please find both build gradles code listed below
\\This is my build gradle in my main project

buildscript {

您需要添加 BoM：

dependencies {
// Import the BoM for the Firebase platform
implementation platform('com.google.firebase:firebase-bom:26.8.0')

// Declare the dependency for the Analytics library
// When using the BoM, you don't specify versions in Firebase library dependencies
implementation 'com.google.firebase:firebase-analytics'

}
