I have push notifications enabled, the app is on the background, and I have a valid (confirmed) Firebase push token. I'm POSTing to https://fcm.googleapis.com/fcm/send with the headers (Authorization: key=APP_SERVER_KEY, Content-Type: application/json), and my body looks like: { "notification": { "title": "Portugal vs. Denmark", "text": "5 to 1" }, "to": MY_PUSH_TOKEN } I'm getting the

问题 I've been struggling to get the example running from below: https://developers.google.com/eclipse/docs/getting_started The first problem I had was didn't have installed 'Google Cloud Messaging for Android Library' in the Android SDK (obvious I know).

问题 I think I have completed every step necessary to convert my messaging app from GCM to FCM but it is not working. FCM is currently returing MismatchSenderId. I have the following services defined in my AndroidManifest.xml . <service android:name=".MyFcmListenerService"> <intent-filter> <action android:name="com.google.firebase.MESSAGING_EVENT" /> </intent-filter> </service> <service android:name=".MyFirebaseInstanceIDService"> <intent-filter> <action android:name="com.google.firebase.INSTANCE

问题 I'm currently implementing Google Cloud Messaging into my app. Basically my app has categories and I need my users to be notifed about recurring events in those categories. I decided to use GCM Topics as a simple way to notify all the users subscribed to a specific category (I will have about 200-300 topics). My question is : Since I don't plan on notifying a single user but instead all users subcribed to a specific topic, is there a point in collecting the registration tokens on my server ?
