Realm in background on Android (Closed App)

Hi everyone, im new here, i develop a android aplication with Realm, but i stuck in something, unknow if is possible, i need that Realm sincronize when the aplication is closed, the reason is for keep always the data updated even if the app is not open, i tried with jobs but the listeners( i need do some stuff when listener changes) only works when the app is in background or first plane and with service realm doesnt work, i need know if is posible some configuration when realm is instanced or other solution for realize it. Thanks !

I think its possible with background processing, it not depends on realm, depends on android platform the way android handle the app when its killed or in background. its have some limitations, but i think its possible
