问题 I have a mix of GCM and FCM Server API keys that belong to different android apps. However I am not the owner of the apps and do not have direct access to the google developer console. Is there a way to detect whether a Cloud Messaging Server API key is enabled for Firebase? I would like to know this so that I can notify the owners of the GCM server keys to update to Firebase. Thanks -David 回答1: There is no way to tell if a Server Key used in the request is from a GCM/FCM enabled project.

问题 Currently I'm working on a SaaS with support for multiple tenants that can enable push notifications for their user-bases. I'm thinking of using a message queue to store all pushes and send them with a separate service. That new service would need to read from the queue and send the push notifications. My question now is: Do I need to come up with a complex sending strategy? I know that with GCM has a limit of 1000 devices per request, so this needs to be considered. I also can't wait for x

问题 Sending messages from one device directly to another device it not supported through Firebase Cloud Messaging. -- Frank van Pufflenen - JUNE 23 2016 That was quite some time ago, and there aren't any updates in the docs. However: Has there been any changes? Is Firebase the only option? Are there any other app servers (Like Firebase and the shut-down Parse )? I don't want to find/buy a server just for this. But is the Firebase Server SDK suitable for this? Can this be implemented using GCM?

问题 I'm struggling to push notifications to Android devices.

问题 I am using eclipse IDE for development. I followed lots of tutorials and implemented push notifications in my project but I'm not getting the GCM Registration id, So my questions is: will eclipse support the push notifications or not? Below is the code snippet; if you need more clarity please comment below. registerReceiver(mHandleMessageReceiver, new IntentFilter(DISPLAY_MESSAGE_ACTION)); Log.v("testing", "testing"); // Get GCM registration id final String regId = GCMRegistrar

问题 I have a little problem with my server and Google Cloud Messaging. I've recently launched an application that sends push notifications each time we publish new posts (1 each 30 minutes). It use /topics/global , so I don't keep in the client registration in memory. The problem is that when server sends notifications (trough CURL, PHP or Shell) the server CPU goes high and other operations slow down. This has happened for some days, maybe because we have more than 4,000 smart phones with the
