【中文标题】无法接收 GCM 通知？【英文标题】：Unable to receive GCM notification? 【发布时间】：2014-05-04 14:33:53 【问题描述】：我正在开发一个 android 应用程序，在该应用程序中我使用 GCM 从我的 php 服务器接收通知，并且我从服务器 i-e 得到了这个响应：-
“multicast_id”：7015234441922271670，“成功”：1，“失败”： 0,"canonical_ids": 0,"results": ["message_id": "0:1344007383866721%2adac3a0ad8b3148"]
我通过谷歌搜索尝试了几乎所有解决方案，但仍然无法在我的设备上接收GCMnotification，我尝试一次又一次地确认我是否输入了正确的项目 ID、Google 服务器 api 密钥但仍然存在同样的问题，请帮助我。

【问题讨论】：
您在发送消息时是否在 logcat 中看到任何内容？ @Eran 是的 "multicast_id":4789513855634684706,"success":1,"failure":0,"canonical_ids":0,"results":["message_id":"0: 1399217879762829%f9286410f9fd7ecd"] 不，这是您在服务器上得到的响应。您应该在您的 android 设备连接到计算机时发送消息，并查看设备日志中是否有任何内容。 @Eran 当我发送消息时我在设备日志中没有得到响应 @Eran 现在我检查了我在我的设备上收到此响应，但没有出现通知“I/GCM Demo(1518): Working... 1/5 @ 1230455 I/GCM Demo(1518) : 工作... 2/5 @ 1230958 I/GCM 演示(1518): 工作... 3/5 @ 1231459 I/GCM 演示(1518): 工作... 4/5 @ 1231961 I/GCM 演示(1518 ): 工作... 5/5 @ 1232463 I/GCM Demo(1518): 已完成工作 @ 1232964 I/GCM Demo(1518): 0.0 I/GCM Demo(1518): 收到: Bundle[message=0.0, android .support.content.wakelockid=1, collapse_key=do_not_collapse, from=31292454533]" 【参考方案1】：我发现我在代码中所做的错误是在GcmIntentService 我注释掉.setSmallIcon(R.drawable.ic_stat_gcm) 所以这就是即使在收到消息后我也看不到通知的原因。
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
//.setSmallIcon(R.drawable.ic_stat_gcm)
