Customize existing Android project (Java) -- 2

I have a running android app for the Delivery Riders which has [login to view URL] and other technologies to ensure a stable connection with the server, work properly on background, send device locations and get notified for new Delivery Order Request. But as the Android version updated, most of the devices are not communicating properly for example not getting order notification on time, not sending device location properly. Especially when in the background, I would like to fix all those issues and make it work properly again.
