Question

我正在尝试在GCM上注册我的应用，但我不知道为什么我的应用从未注册过。调用GCMRegistrar.register(this, SENDER_ID);但从未调用GCMIntentService中的onRegistered（）。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
01-17 11:03:06.070: V/GCMBaseIntentService(3509): Acquiring wakelock

我不知道出了什么问题以及为什么永远不会调用onRegistered（）。任何帮助将不胜感激。

Answer 1

我在另一篇文章中想到了什么问题。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，

添加以下意向服务

<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，如此另一个post所示。

Answer 2

我回答是因为粘贴代码在评论中几乎无法读取：

我遗漏了一些来自logcat的日志，这些日志表明您的服务甚至被调用。注册时我在我的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您忘记粘贴它。你能确定你发布了完整的LogCat吗？过滤GCM以确保您没有错过任何内容。

<强>更新

正如评论中提到的OP，他使用该服务做了更多。这在某种程度上干扰了GCM功能，并在将其分成两个服务之后起作用。经验教训：不要将GCMIntentService用于GCM以外的任何其他内容。

来自GCMIntentService的onRegistered（）从未被调用过
