I'm new on sending push notifications on android. I try to send push notification for my testing application periodically. But sometimes device can't receive the notification. I searched about it and i think the problem is because of connection lost between server and my device. I think the solution is sending an heartbeat network packet on the push connection but i don't know how can i do it and to which server i should do it?
There is an application on google play store called as Push Notifications Fixer and i think this work is what i want to do
