Question

我正在尝试向我的应用添加推送通知..我一直关注Ravi Tamada的博客http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/

顺便说一句，我能够使用我的发件人ID和注册ID运行个别项目，所有推送通知都运行良好..当我尝试在我的应用程序中实现此问题时出现问题..当项目正在运行时，应用程序在 CHECKING REGID = NULL

之后停止

应用程序没有崩溃..它只是停止因为服务器没有响应而没有发生意图

我的坏..我有多个包..服务有正确的包名..类别

也是如此

那应用程序出了什么问题？为什么不起作用？

这是我的应用程序的日志猫，包括推送

  onReceive: com.google.android.c2dm.intent.REGISTRATION
  GCM IntentService class: com.example.smss.GCMIntentService
  V/GCMBaseIntentService(2959): Acquiring wakelock

这是我的清单。。

Answer 1

似乎您没有正确实现GCMIntentService类。在 AndroidManifest.xml：

中执行此操作

<service android:name="com.example.smss.GCMIntentService" />

并在正确的包名称中创建相应的类。其余的你可以按照教程..
