来自GCMIntentService的onRegistered()从未被调用过

Question

我想在GCM上注册我的应用程序,但我不知道为什么我的应用程序从未注册.GCMRegistrar.register(this, SENDER_ID);被调用但我的GCMIntentService中的onRegistered()从未被调用过.我不知道为什么.

这是我的Logcat

01-17 11:03:00.015: D/GCMRegistrar(3509): resetting backoff for com.abc.xyz.ui.activity
01-17 11:03:03.210: V/GCMRegistrar(3509): Registering app com.abc.xyz.ui.activity of senders 964256581311
01-17 11:03:06.070: V/GCMBroadcastReceiver(3509): onReceive: com.google.android.c2dm.intent.REGISTRATION
01-17 11:03:06.070: V/GCMBroadcastReceiver(3509): GCM IntentService class: com.abc.xyz.ui.activity.GCMIntentService

我不知道出了什么问题,为什么onRegistered()永远不会被调用.任何帮助将不胜感激.

Answer 1

我在另一篇文章中想出了什么问题.我的GCMIntentService类在我的清单中定义为

<service android:name="MY_PACKAGE.gcm.GCMIntentService" />

因为我不想把这个类放在root包中,而是把它放在MY_PACKAGE.gcm".这似乎引起了一个问题,正如文档所说,

添加以下意图服务

<service android:name=".GCMIntentService" />

所以,当我转移到root包时,它工作了!还有另一种方法可以将GCMIntentServiceSubclass放在任何位置,并以不同的方式命名.您应该将GCMBroadcastReceiver子类化,并在清单和子类中进行更改,如此其他帖子所示.

Answer 2

我回答是因为在注释中粘贴代码几乎难以阅读：

我从你的 logcat 中丢失了一些日志，这些日志表明你的服务甚至被调用了。注册时我的 Logcat 中有这个：

GCMBroadcastReceiver  V  onReceive: com.google.android.c2dm.intent.REGISTRATION
GCMBroadcastReceiver  V  GCM IntentService class: com.package.android.app.GCMIntentService
GCMBaseIntentService  V  Acquiring wakelock
GCMBaseIntentService  V  Intent service name: GCMIntentService-DynamicSenderIds-1

特别是最后一行丢失或者您忘记粘贴它。您能确保您发布了完整的 LogCat 吗？进行筛选以GCM确保您没有错过任何内容。

更新

正如OP在评论中提到的，他使用该服务做了更多事情。这在某种程度上干扰了 GCM 功能，将其分成两个服务后它就可以工作了。经验教训：不要将 GCMIntentService 用于 GCM 以外的任何其他用途。
