推荐答案

由于按照谷歌播放服务安装指南，一个不只需添加罐子。 由于GPS捆绑了资源，你必须导入它作为一个新的单独项目，并从自己的引用它，已有的项目。

Adding Google Play Services support to your project

As per the Google Play Services setup guide, one does not simply "add the jars". Since GPS comes bundled with resources, you have to import it as a new seperate project, and reference it from your own, exisiting project.

请按照安装向导。我只是验证我可以引用 AD浏览报从我自己的项目纳入GPS成功。

Please follow the setup guide. I've just verified that I can reference AdView successfully from my own project incorporating GPS.

GPS是一个外部服务 - 这是由Play商店应用管理的APK，你需要确保用户拥有一个符合你想做的事了最新的GPS APK和/或一个。下面是指南：确保设备具有谷歌播放服务APK 。

GPS is an external service - it's an APK managed by the Play Store app and you need to ensure that the user has the latest GPS APK and/or one that complies with what you wanna do. Here is the guide: Ensure Devices Have the Google Play services APK.

如果设备没有安装GPS（不是谷歌的设备，特殊的ROM，AOSP ROM，旧的Andr​​oid，等...），你不能使用AD浏览报。

If the device does not have GPS installed (not a Google device, special ROM, AOSP ROM, old Android, etc...) you can not use AdView.
