Android GCM服务器已发送，但GCM未推送至设备 [英] Android GCM server sent but GCM not pushing to device

问题描述

我在手机上测试GCM。 （2.3.6 android）。
$ b

清单文件（MainActivity，First和Second activity不做任何事情，它们用于其他测试目的，不干扰GCM） 。

GCMBroadcastReceiver

  public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
 
 @Override 
 public void onReceive（Context context，Intent intent）{
 //明确指定GcmIntentService将处理意图。 
 ComponentName comp = new ComponentName（context.getPackageName（），
 GcmIntentService.class.getName（））; 
 //启动服务，保持设备在启动时保持清醒状态。 
 startWakefulService（context，（intent.setComponent（comp）））; 
 setResultCode（Activity.RESULT_OK）; 
 
 
  

GCMIntentSErvice

  public class GcmIntentService extends IntentService {
 public static final int NOTIFICATION_ID = 1; 
 private NotificationManager mNotificationManager; 
 NotificationCompat.Builder构建器; 
 
 public GcmIntentService（）{
 super（GcmIntentService）; 
} 
 public static final String TAG =GCM Demo; 
 
 @Override 
 protected void onHandleIntent（Intent intent）{
 Bundle extras = intent.getExtras（）; 
 GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance（this）; 
 // getMessageType（）意图参数必须是您在BroadcastReceiver中收到
 //的意图。 
字符串messageType = gcm.getMessageType（intent）; 
 
 if（！extras.isEmpty（））{//具有不合格的效果Bundle 
 / * 
 *根据消息类型过滤消息。由于GCM很可能在未来使用新的消息类型进行
 *扩展，因此忽略任何您感兴趣的消息类型或您不认识的消息类型。 
 * / 
 if（GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals（messageType））{
 sendNotification（Send error：+ extras.toString（））; 
} else if（GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals（messageType））{
 sendNotification（服务器上的已删除邮件：+ extras.toString（））; 
 //如果是常规的GCM消息，请做一些工作。 
} else if（GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals（messageType））{
 //此循环表示服务正在进行一些工作。 （标记i = 0; i <5; i ++）{
 Log.i（标记，正在工作...+（i + 1）
 +/ 5 @ + SystemClock.elapsedRealtime（））; 
尝试{
 Thread.sleep（5000）; 
} catch（InterruptedException e）{
} 
} 
 Log.i（TAG，Completed work @+ SystemClock.elapsedRealtime（））; 
 //发送收到的消息通知。 
 sendNotification（Received：+ extras.toString（））; 
 Log.i（TAG，Received：+ extras.toString（））; 
} 
} 
 //释放由WakefulBroadcastReceiver提供的唤醒锁。 
 GcmBroadcastReceiver.completeWakefulIntent（intent）; 
} 
 
 //将消息放入通知中并发布。 
 //这只是您可能选择使用
 // GCM消息做的一个简单示例。 
 private void sendNotification（String msg）{
 mNotificationManager =（NotificationManager）
 this.getSystemService（Context.NOTIFICATION_SERVICE）; 
 
 PendingIntent contentIntent = PendingIntent.getActivity（this，0，
 new Intent（this，DemoActivity.class），0）; 
 
 NotificationCompat.Builder mBuilder = 
 NotificationCompat.Builder（this）
 .setSmallIcon（R.drawable.abc_ab_solid_dark_holo）
 .setContentTitle（GCM Notification）
 .setStyle（new NotificationCompat.BigTextStyle（）
 .bigText（msg））
 .setContentText（msg）; 
 
 mBuilder.setContentIntent（contentIntent）; 
 mNotificationManager.notify（NOTIFICATION_ID，mBuilder.build（））; 
 
 
 
 
 
 
 $ b现在，我可以从服务器发送消息显示
 
 
将POST请求发送至网址：
  https://android.googleapis.com/gcm/send 响应码：200 
 {multicast_id：5410443299609525979，success：1，失败：0，canonical_ids：0，results：[{message_id：0：1409160055237618％a13ced80f9fd7ecd}]}  
但在此之后，我看不到在我的手机上生成通知。这里发生了什么。这可能是什么原因？
 
我连接到家里的wifi，我的手机上也有激活的数据包，所以即使我解散了wifi （不知道为什么这会影响，但解决方案这里建议），但仍然没有收到任何通知。 
 
 
 
任何帮助将不胜感激。       您的接收器中存在错误的类别（< category android：name =com。 google.android.gcm.demo.app/> ）。将其更改为 com.example.testconnectionapp ，假设这是您应用的软件包名称。

    .setContentText(msg);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
Now, I can send the message from server as it shows 

  
Sending 'POST' request to URL :
  https://android.googleapis.com/gcm/send Response Code : 200
  {"multicast_id":5410443299609525979,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1409160055237618%a13ced80f9fd7ecd"}]}
But after that I do not see the notification getting generated on my phone. What is happening here. What could be the possible reasons for this?

I am connected to the wifi at home, also I have data pack activated on my phone, so even if I disconnet the wifi (not sure why that would impact anyway, but the solution here suggested) but still I am not getting any notification generated. 

Any help will be highly appreciated. 
解决方案
You got the wrong category in your receiver (<category android:name="com.google.android.gcm.demo.app" />). Change it to com.example.testconnectionapp, assuming that's your app's package name.
