Push notification for new message in Android

Hi,
we have implemented rocket chat sdk in Android and the chat is working good. But now we want to enable push notification feature for it. We configure an google account and gave necessary details to the Rocket Chat Admin Administrative account. But unfortunately the device does not receive any notification when we click on Test Push button. Please help.

Thanks.

Removed your connection information. Please don’t post those. This is a public forum.

Have you included the gcm stuff in your application code? Also are you sending the device token to rocket.chat?
