The Android Oreo changelogs are out, and there are some interesting additions which many already know about. There’s Project Treble, security changes and so on. One of the biggest changes is how background applications behave. They no longer have free reign over the device, and Android System will induce restrictions on anything abusing a background process.
In the Android Oreo Compatibility Definition Document, Google specifically states that OEMs are not to tamper with the background app limitations. I included a screenshot of the section mentioned below.
Google seems to realize that certain OEMs love to implement their own versions of background app management features, but in doing so it causes a massive headache for application developers who don’t know how their app might behave on certain devices.
Thus, this is a good change both for end users and developers alike.
