地图Android SDK是一套Android系统地图开发调用的接口，地图数据可以覆盖海外绝大多数国家，支持多种语言。地图采用WGS84 GPS坐标系，满足绝大多数海外地图开发的需求。您可以轻松地在自己的Android应用中加入地图相关的功能，包括：
您可通过地图服务SDK可以开发地图相关的App，比如：
集成Map Kit能力，您需要完成以下准备工作：
1. - 登录AppGallery Connect网站，选择"我的项目"。
2. - 在项目列表中找到您的项目，在项目下的应用列表中选择需要开通地图服务的应用。
3. - 前往"项目设置 > API管理"中开启"地图服务"权限。

}
@Override

Kotlin示例代码如下：
override fun onStart() {

mMapView?.onStart()
}
override fun onStop() {

mMapView?.onStop()
}
override fun onDestroy() {
super.onDestroy()

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地图Demo后，查看地图是否能够展示。
干得好，您已经成功完成了codelab并学到了：
