I am using the C2DM notification service. When I send 2 consecutive notifications, I only see the second. My question is, can notifications receive the same service?
I do not understand your question, but if two messages sent from the same collapse_keyto the first are processed by the device, the server automatically deletes the first. Therefore, if you need to send several messages, change the key value.You can read a little more about this here: https://developers.google.com/android/c2dm/?hl=sv-SE#push
