无法接收来自GCM的消息
正在开发一个使用GCM发送和接收消息的Android应用程序。 am能够向GCM注册我的应用并接收GCM注册令牌。但我没有在收到新邮件通知。(好像没有在我的MyGcmListenerService类hapenning。)无法接收来自GCM的消息
我只能看到在重装我聊天的用户界面我的新邮件(即单击后退按钮和然后再次单击我的聊天按钮。没有什么是发生在我的MyGcmListenerService.java !!!!)
下面是我的班和AndroidManifest.xml中

问题
如何我可以解决我的问题,并能即时接收邮件,而不来回?
调试后我的申请,这都是警告AM充分利用logcat的

我终于解决了我的问题,这是存在的,因为我不是从GCM服务器得到它后发送GCM注册ID到我的应用服务器。
但是,在将它发送到我的应用程序服务器后,我的客户端应用程序能够在收到新消息时收到通知。
任何人遇到同样的问题。这是的应用无法从GCM收到通知或消息(或两者),请确保您已经(在程序上)发送GCM注册令牌你的应用服务器
像这样的事情
public class RegistrationIntentService extends IntentService {
public static final String GCM_SENDER_ID = "Your ProjectID";//your project id

}
String regId;

GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
regId = token;
// [END get_token]

试一试!
请让我知道什么是msgId是在String id = Integer.toString(msgId.incrementAndGet());那么在下面的行什么是gcm和GCM_TIME_TO_LIVE? gcm.setnd(GCM_SENDER_ID +“@ gcm.googleapis.com”,id,GCM_TIME_TO_LIVE,data);和我们必须给我们的第三方服务器的网址?请让我知道.... – shripal
@shripal你收到了什么错误? –
我没有收到错误,但没有收到来自服务器的任何通知...只是我想确保我的应用程序注册在服务器端或不是?或者我必须调用任何Web服务将令牌发送到服务器端? – shripal
所以你的意思是你收到消息?只是他们没有及时显示或没有刷新页面? – Skynet
@Skynet正是男人。我的通知机制没有被触发! –
@Skynet你认为哪里错了?我已经挣扎了近2周! –
