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

Question

请让我发现问题，运行我的应用程序后，作出改变，这些文件添加了防火墙依赖关系。你的帮助将不胜感激。

不过，我的应用程序最初是工作的，但是在将防火墙依赖项添加到Gradle构建之后，我得到了一个构建失败的异常。我读过许多关于Stackoverflow的解决方案，但是它们并没有解决我的问题。请在下面找到我的代码

Answer 1

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'

}
