GCM SERVICE_NOT_AVAILABLE on Android 2.2

Question

I am getting the error \"SERVICE_NOT_AVAILABLE\" on my GoogleCloudMessaging.register() call on a Android 2.2 device.

I am writing an app that uses GoogleCloudMessagi

Answer 1

This error also occurred to me, but it did because I was trying to register in the GCM through a firewall of my company. And in the documentation I found:

"Note: If your organization has a firewall that restricts the traffic to or from the Internet, you need to configure it to allow connectivity with GCM in order for your Android devices to receive messages. The ports to open are: 5228, 5229, and 5230. GCM typically only uses 5228, but it sometimes uses 5229 and 5230. GCM doesn't provide specific IPs, so you should allow your firewall to accept outgoing connections to all IP addresses contained in the IP blocks listed in Google's ASN of 15169."

Once I opened the ports or tried from another network, it worked.
