I'm following the below instructions, but the response is always HTTP 401 Unauthorized. I have verified that the ID token, registration ID, and project ID (number) are all valid. Unfortunately the response does not provide a detailed reason.
https://developer.android.com/google/gcm/notifications.html#gen-client What is necessary to receive an HTTP 200 response with the notification_key? I'm wondering if the documentation is missing an important detail or if there is a known issue with the service. Otherwise GCM and the Google auth token are working fine for me. Here is a redacted net log. Does the request require any other headers or JSON fields that are not specified in the documentation? ---> HTTP POST https://android.googleapis.com/gcm/googlenotification project_id: {project-number}Content-Type: application/json; charset=UTF-8{"id_token":"{long-auth-token}","notification_key_name":"{unique-name}","operation":"add","registration_ids":["{reg-id}"]} <--- HTTP 401 https://android.googleapis.com/gcm/googlenotification -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
