Android Question socket connection in a background service

[Addo]

Hi, I wonder is there any solution to keep a socket connection alive when the phone sleep or in the background for a long time?
the current situation is when a user puts the phone to sleep or put the app in the background for a while the service keeps running but the socket connection gets disconnected. I tried everything to avoid this behavior starting from sending a message periodically within a timer inside the service to keep the socket running.
and I have set the power manager as following

how to set power manager wake lock with the following rules

in java, I can set the power manager to keep a socket connection alive like following PowerManager.WakeLock newWakeLock = ((PowerManager) getSystemService("power")).newWakeLock(1, "Socket:WakeLock"); also with wifi WifiManager.WifiLock createWifiLock = ((WifiManager)...

but that won't change anything. any way to avoid the socket disconnection when the phone in the background?

Have you created a foreground service and also acquired a partial lock?

Best solution is to switch to push notifications.
