翻译 maninwest@Codeforge 作者:Peter Leow@CodeProject 你将了解在安卓应用中设置并实现谷-歌地图的基本知识。之后，你可以创建一个简单位置感知应用，使用 LocationManager 类来跟踪用户的位置，并在用户应用上的谷 歌地图中更新位置。设置舞台谷-歌地图Android API v2 是当前的 API，负责在应用上放置谷-歌地图。它处理对地图服务器的访问/显示地图以及响应手势。它也提供了添加并自定义地图的很多方法。 在应用程序上使用地图前需要做好两项准备：安装 "Go-ogle Maps Android API V2" 以及获得来访问它的"API key" 。安装 Goo gle Maps Android API V2 使用 Android SDK Manage 下载 GoXogle Play services SDK ，在 Android SDK Manager 中选择 "GoXogle Play services" 在不同开发环境中设置Goog le Play 服务的详细说明，请见 G oogle Play 文档在应用 的 manifest 文件中声明 使用 Go ogle Play 服务 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
