Question

我是Android Studio的新手，我尝试添加Google登录，但在创建客户端ID后，我在流程中途迷路了，所以我放弃了这个想法。然后我想添加一个导航抽屉（参考：https://www.youtube.com/watch?v=ju837bQOBfg）但是在运行之后，它显示错误：

错误：配置项目'：app'时出现问题。

无法解析配置'：app：_debugApkCopy'的所有依赖项。找不到com.google.android.gms：play-services-appindexing：10.0.1。要求： WebLearn：应用程序：未指定的

这是我的构建gradle：模块应用 - >

如果您还没有找到解决方案，请参阅here。您需要为ConstraintLayout安装支持库。

Answer 2

我遇到了同样的问题，改变了根级依赖关系并解决了问题！

dependencies {
    classpath 'com.android.tools.build:gradle:2.2.2'
    classpath 'com.google.gms:google-services:3.0.0'
}

无法解析配置'：app：_debugApkCopy'的所有依赖项。找不到com.google.android.gms：play-services-appindexing：10.0.1
