android-对于已卸载的registration_id,没有NoRegistered消息

我使用以下方法获得了注册ID：

String regid = (GoogleCloudMessaging.getInstance(this)).register("My_Sender_ID");

并将其存储在我服务器上的数据库中.稍后,当卸载应用程序时,我尝试发送一条消息,我希望收到一条NotRegistered错误消息,查看该错误消息是从数据库中删除相应的ID.

但是问题在于,它仍然会像其他成功案例一样返回me_message_id.我想测试更多时间,等待了一个小时,现在我得到了正确的消息.

[error] => NotRegistered

那么,这种延迟是预期的吗？

谢谢

解决方法:

是的,这种延迟是预期的.

卸载应用后,第一次尝试发送消息时,GCM服务器尝试将其发送到设备,并发现您的应用已不再在该设备上注册GCM.

在卸载后第二次尝试发送消息时,您收到NotRegistered错误,因为这次GCM服务器知道该注册ID不再被注册.

您无需等待一个小时即可尝试再次发送.

Note: When users uninstall an application, it is not automatically
unregistered on GCM. It is only unregistered when the GCM server tries
to send a message to the device and the device answers that the
application is uninstalled or it does not have a broadcast receiver
configured to receive com.google.android.c2dm.intent.RECEIVE intents.
At that point, your server should mark the device as unregistered (the
server will receive a NotRegistered error).
