I have already red many posts about the subject, some of these works, but only on some devices. For example it works on my Nexus 4, Nexus 5 with cyaogenmod, but not on my Xiaomi Mi2s (jelly beam 4.1.1)
I tried setting it sticky, using alarm, and broadcast receiver on destroy. But neither of them worked out. When I kill the application it never wake up again. But on the same device Whatsapp works perfectly, and even if I kill it, it wake up again..
Is there any way to do it without use GCM?
Some of the link I already looked up:
How to restart a killed service automatically?
Service that repeatedly runs a method, after an amount of time
