我想在我的 Android应用程序中使用GCM服务.

为此,我使用了http://developer.android.com/guide/google/gcm/gcm.html的android文档

我创建了客户端注册过程与发件人ID等和服务器端应用程序,我使用注册ID和发件人ID发送邮件.

当我通过Eclipse在我的手机中安装应用程序时,推送通知工作正常,因此我拥有的发件人ID是正确的.

然后,当我用Eclipse导出apk文件并将其安装在我的手机中时,我收到SenderId错误的错误消息

MissmatchedSenderId

任何人都知道为什么我会得到这个.

我读过这些话题：

Why do I get “MismatchSenderId” from GCM server side?

When sending messages using GCM,I keep getting the response ‘MismatchSenderId’

但在我的情况下奇怪的是,在将应用程序导出为apk之前一切正常,然后我遇到了这个问题.

任何想法都是最好的.

我实际上遇到了同样的问题,并且正在研究超过10个小时.

我终于找到了问题！
与服务器API密钥或浏览器API密钥或SenderID无关.
问题是Google文档：

final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
  GCMRegistrar.register(this,SENDER_ID);
} else {
  Log.v(TAG,"Already registered");
}

Google表示你必须调用getRegistrationId函数并且只有当id为空时才调用register！
这对我来说根本不起作用……当我这样做时,我总是在发送到这个regId时找回MismatchSenderId.

我的解决方案是：
总是打电话

GCMRegistrar.register(this,SENDER_ID);

而当功能

protected void onRegistered( Context c,String regId )

被称为在我的服务器数据库中保存regId.

如果我这样做,一切正常！

一旦应用程序启动或从服务器发送推送通知,就会发生以下回溯.

编辑：选择项目并转到：Properties-> Java Build Path-> Order and Export,确保在列表中选中了android.support.v4库,如果没有,请标记它. (我假设您已经将库导入到项目中),清理项目并且它应该可以工作

我已经整理了一个骨架客户端/服务器GCM应用程序,该应用程序接受并在我的粗略和准备好的服务器上显示我的 Android手机上的消息.我说’骨架’和’粗糙和准备’,因为我的应用程序的registration_id被硬编码到服务器端,作为我在调试器中捕获的值,当我启动示例Android应用程序并在GCM服务器上注册应用程序/设备组合时.当我开始思考时,我正要开始为双方提供读/写机制来访问服务器上的简单数据库以存储reg_id /设备组合：

我知道这个reg_id可以随时过期,因为谷歌说它可以.从文档中可以清楚地看到如何检查id是否仍然正常,并且它是一个很大的IF,我再次启动应用程序.但是,为什么我或任何其他用户再次启动它？在清单中注册的GCMIntentService根据需要在那里收集消息,并且无需出于任何原因再次运行应用程序.因此,当id到期时,我将停止获取消息 – 服务器可能从返回代码中知道,但无法通知我的应用程序 – 无法恢复,除非我再次运行应用程序并通过其onCreate()并且可能registerClient()方法.

那么当id到期时会发生什么？我没有看到IntentService中的任何on ..方法都会执行.谷歌自己会发一条正常消息说它即将到期吗？我是否需要编写一个每天运行的警报任务并检查ID？

根据 GCM：

An existing registration ID may cease to be valid in a number of
scenarios,including:

• If the application manually unregisters by issuing a com.google.android.c2dm.intent.UNREGISTER intent.
• If the application is automatically unregistered,which can happen (but is not guaranteed) if the user uninstalls the application. If the registration ID expires. Google might decide to refresh registration IDs.
• If the application is updated but the new version does not have a broadcast receiver configured to receive com.google.android.c2dm.intent.RECEIVE intents.

考虑与注册相关的响应将触发“com.google.android.c2dm.intent.REGISTRATION”意图.因此,您应该注意从GCM发送的注册消息.

更新

GCM doc说：

If the registration ID expires. Google might decide to refresh
registration IDs. For all these cases,you should remove this
registration ID from the 3rd-party server and stop using it to send
messages. Happens when error code is NotRegistered.

考虑到上述事实,然后在您的服务器上,您应该处理过期的ID并在您的数据库中设置一个标志,下次您的Android客户端检查您的服务器(最后您必须进行定期检查)或调用isRegisteredOnServer在GCMRegistrar类上得到错误的结果,你应该激活REGISTRATION意图以获得一个新的ID.
