It will not work unless you keep the screen turned on. Consider using push notifications instead.

Most of my target devices don't have google services... Is there any alternative of push notifications?

Did you enable the app in energy savings to run in the background (newer Android versions don't allow "unnown" apps to do so by default)

Click to expand...

Yes, I followed this method and my app is listed as "not saving battery" in Android. No effect though.

I have a cheap china tablet which works ok but after some time WiFi seems to be switched off (have to manually switch it on again). Maybe the network doesn't work anymore. You could "ping" a website via OkHttpUtils (simple request) and log if there's a problem after some time (UDP doesn't have any error handling or handshake).
