android中的GCM(谷歌云消息)推送通知
我正在尝试使用GCM推送通知。我的设备已注册到服务器,并且我还创建了设备注册id。但是,当我试图从服务器发送消息时,该消息不会发送到已注册的设备。有人能帮我吗 我的主要活动 包com.ati.gcm 导入com.google.android.gcm.gcmregistar 导入android.os.AsyncTask 导入android.os.Bundle 导入android.app.Activity 导入android.content.BroadcastReceiver 导入android.content.Context 导入android.content.Intent 导入android.content.IntentFilter 导入android.util.Log 导入android.view.Menu 导入android.widget.TextView 导入android.widget.Toast 导入静态com.ati.gcm.CommonUtilities.DISPLAY\u MESSAGE\u ACTION 导入静态com.ati.gcm.CommonUtilities.EXTRA_消息 导入静态com.ati.gcm.CommonUtilities.SENDER\u ID 公共类MainActivity扩展了活动{android中的GCM(谷歌云消息)推送通知,android,push-notification,google-cloud-messaging,Android,Push Notification,Google Cloud Messaging,我正在尝试使用GCM推送通知。我的设备已注册到服务器,并且我还创建了设备注册id。但是,当我试图从服务器发送消息时,该消息不会发送到已注册的设备。有人能帮我吗 我的主要活动 包com.ati.gcm 导入com.google.android.gcm.gcmregistar 导入android.os.AsyncTask 导入android.os.Bundle 导入android.app.Activity 导入android.content.BroadcastReceiver 导入android.c

您是否将客户端的GCM id发送到您的服务器,服务器通过该id和GCM服务器与客户端通信。
您是否已将GCM权限插入您的舱单?
GCMinentService.java是否位于项目的主包中?
广播接收器的邮政编码?检查API密钥。向设备发送消息时是否出现未经授权的错误?也为你的接收者显示代码。你的接收者发布代码。查看并演示如何实现GCMi。我检查了你的所有建议,但无法工作。谢谢,谢谢。是的,我的API密钥错了。我正在创建一个新项目,并使用新的API密钥,它运行良好。
