Send push notification for one app

Question

I have many application on android. And some users are share the same register ID. How can I specify and send the push notification to a specific app?

Answer 1

Different applications have different registration ids on the same device, so you shouldn't have any problem. What do you mean by users are share the same register ID ? Do you mean users of the same application on the same device? That's the only case where they can share a registration ID.

Even if you use the same Google API project ID when you register the different Apps for Google Cloud Messaging, you'll still get a different registration ID for each app. I tested it.

Answer 2

如果您无法更改注册ID流程来唯一标识您的应用程序（最佳解决方案），则可以发送带有GCM消息的有效负载 ，并使您的应用程序忽略没有特定有效负载的GCM消息。
