位置服务SDK提供位置查询服务，既能帮助您的用户更加方便地使用位置相关服务，还能帮助您快速获取用户。Site Kit通过提供如下核心能力，帮助您快速构建基于位置服务的产品，满足用户对探索周边地点的需求：
您通过位置服务SDK可以开发围绕位置搜索的App，比如：
集成Site Kit能力，您需要完成以下准备工作：

使用Android Studio自带的Gradle编译工具，双击"installDebug"，即可安装Demo。
打开开发调试版本的位置服务App后，查询字符串已预置Eiffel Tower，点击"Search"，查看是否能获取到结果。
干得好，您已经成功完成了codelab并学到了：
