Android Nougat brings us updates to data saver. You can turn on data saver and allow unrestricted data access as a white list to a select few apps.
If you're not familiar with this feature, please check out the feature spotlight on Android Police http://www.androidpolice.com/2016/03/09/android-n-feature-spotlight-new-data-saver-option-reduces-data-usage-on-limited-cellular-plans/
Obligatory:
Seriously. AP has shown themselves to be the only Android news blog
that takes itself seriously. They consistently produce new, useful,
substantiated content. I don't see many other android journalists (or
even other journalists in other fields) do as fantastic of a job as you
guys do.
The APK teardowns, fantastic sources of information.
Don't see others doing this. You don't just post "Oh boy i think this is
happening rumor rumor rumor." You go through the code line by line to
see what it could mean. That's dedication.
Every week, the "x apps
of the week." Awesome! What a great way to find apps. Original reviews,
insightful and honest opinions, I love it!
All other general
news. Always original content. Rarely do I see recycled "this rumor
happened" and "this is coming out" like I do from literally every other
blog.
Getting to know Android x.x.x. Perfect. Probably my favorite recurring thing on any blog ever.
Basically,
what I'm trying to say, is thank you so much for putting out actual
content. Thank you for not trying to get pageviews from "hot" titles and
"latest rumors!" Thank you for trying to get pageviews from writing
solid articles and putting thought into almost every post.
Seriously,
I love you guys. I hope you can tell from all the upvotes and how many
of your stories hit the front page! But even still, I wanted to let you
know how absolutely grateful I am (and we all are)! Stick around, and
keep up the fantastic work! We don't take it for granted, even if it
might seem like it sometimes!
**tl,dr; I LOVE YOU ANDROID POLICE! THANK YOU FOR EVERYTHING! <3**

With that out of the way, lets get to the real reason for this post: unrestricted data access. Those who know me will also know what I yell all the time. I mean besides "timber". Yes, defaults matter. By default, when I turn on data saver on my nexus 6 with the latest Nougat, Google carves out a small exception for Google Play services. I believe this allows Google to send and receive heart beats from and to the device. Now, I don't want you to go crazy but if there is some notification that is super duper important for the user and you're absolutely sure they would want it, you can try to send the notification through Google Cloud Messaging. I haven't tried it yet though so I could be completely wrong but give it a shot.
