android - 未找到 Google Play 服务资源 - 推送通知

Question

我正在按照 Google 教程在 Android 上安装推送通知。我正在使用 Google Play 服务模块，因为 Google Cloud Messaging 最近被弃用。

教程:Google Cloud Messaging - Google Play Services

但是当我启动该应用程序时出现以下错误:

不过 Google Play 服务已被添加。

不知道问题出在哪里。有人不能帮助我吗？非常感谢!

我从未玩过推送通知，但我正在使用 google play 服务。您应该将 google-play-services_lib 文件夹添加为单独的项目，并将其作为库添加到您的 Android 项目中。

1. 导入 google-play-services_lib(同时勾选复制到工作区)。您可以在sdk floder -> extra > google -> google_play_services -> libproject -> google-play-services_lib

2. 将新创建的项目设置为库(在eclipse -> build path -> android -> 勾选“is Library”并确定。

3. 转到您的 android 项目的构建路径 -> android -> 添加 -> 添加您刚刚创建的 google-play-services_lib 库。

希望对你有帮助(-:
