If you think that's cool, check out the AdGuard app for Android. It handles not just browser traffic, but traffic from every app. Not the one from the Play Store, but the one from their website -- the Play version is crippled. It'll block all those undesirable connections for the entire device, and it's GUI makes it super easy.

It is not free, however, but I believe they offer a trial still.

On my last Android device, after months of usage, I was blocking on average about 40% of all traffic on my phone -- most of that to trackers and ad networks. On Android it seems like most every app is sucking away at your device, almost none of the tracking and ad network activity is voluntary or opt-in.
