Kotlin MainActivity 导入未注册

Question

我们正在尝试添加 youtube 视频的缩略图，并通过代码将其链接到 youtube 应用程序。我们已将所有实现同步到 build.grade。 (app) 文件，但导入不起作用并显示为红色。有没有可能我们使用的是不再有效的旧进口产品？

我们已经尝试查找进口商品，但没有任何结果。我们尝试重新键入导入，而不是将其复制粘贴到以前可以工作但现在不起作用的 IDE 中。代码中有更多错误，但我相信这是因为导入没有通过，所以其中一些工具将无法工作。

添加到 build.grade (app) 的实现

implementation 'com.google.api-client:google-api-client:1.31.3'

implementation 'com.google.apis:google-api-services-youtube:v3-rev20220225-1.31.3'

implementation 'com.github.bumptech.glide:glide:4.12.0'
