使用GCM服务从不会调用BroadcastReceiver [英] BroadcastReceiver is never called using GCM service

问题描述

我试图为推送通知实施GCM的新服务。
我已经看到一些关于该问题的类似帖子，其中大多数都指向缺少某些东西的Manifest。
找不到我在那里丢失的东西：

Manifest.xml 这是efecting的东西）

 $ b private void sendNotification（String msg）{

 this.getSystemService（Context.NOTIFICATION_SERVICE）; 
 
 PendingIntent contentIntent = PendingIntent.getActivity（this，0，
 new Intent（this，FbActivity.class），0）; 
 
 NotificationCompat.Builder mBuilder = 
 new NotificationCompat.Builder（this）

 .bigText（msg））
 .setContentText（msg）; 
 
 mBuilder.setContentIntent（contentIntent）; 
 mNotificationManager.notify（NOTIFICATION_ID，mBuilder.build（））; 
} 
} 
  

我使用这一行发送massege：

  gcm.send（SENDER_ID +@ gcm.googleapis.com，id，data）; 
  

sender_id是我在google api console上的项目编号，并且id始终相同（1） 。

解决方案

gcm.send 用于从应用程序发送GCM消息到您的服务器（通过GCM云连接服务器）。您的清单看起来很好，但为了让 gcm.send 做任何事情，您必须有一台服务器连接到GCM Cloud Connection Server。而且，由于您试图向服务器发送消息，因此您的设备中不会看到任何内容（即使消息已成功发送到您的服务器），并且不会调用BroadcastReceiver（除非您的服务器将消息发回给设备）。

}

I'm using this line to send the massege:

gcm.send(SENDER_ID + "@gcm.googleapis.com", id, data);

The sender_id is my project number at google api console, and the id is always the same (1).

解决方案

gcm.send is for sending GCM messages from your application to your server (via GCM Cloud Connection Server). Your manifest looks fine, but in order for gcm.send to do anything, you must have a server connected to GCM Cloud Connection Server. And since you are trying to send a message to the server, you won't see anything in your device (even if the message was sent successfully to your server) and BroadcastReceiver won't be called (unless your server sends a message back to the device).

这篇关于使用GCM服务从不会调用BroadcastReceiver的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
