I would like to know whether the background service for any application can be provided by xiaomi? I have service in my app which need to be running in background all the ti
you wont be able to do that from code until and unless there is some api from xiaomi that gives you access to that functionality. I am guessing auto start manager is an app( with privileges of that of a system app, since part of xiaomi modified os) , hence not possible. On the other-hand if the device is rooted you can actually disable autostart manager.
Still whatsapp , facebook and many more apps doing this may be because of they have tie ups with Xiaomi to be in the whitelist. But its just a guess.
