[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] samep:
I've been working at this with Adaway white lists and redirects before lollipop came because of the Xposed delays and also had it unravel in lollipop. My problem was the webserver stopped; it needs to be enabled and running, you can check by opening the app and see if it's still on. I had uninstalled and reinstalled to no avail until I got the latest one and restored my data to it.

Can't guarantee this works for all ads or redirects because the setup is complex and not thoroughly tested. Also includes redirects that may not apply to everyone but it's friendly with Hulu, Spotify, Tapatalk and YouTube.

7 simple steps; steps 2 and 3 are optional.

1) Get this Adaway version or latest from xda, credit/thanks to the OP, [MENTION=3355398]mrRobinson[/MENTION], if it works for you.

Note: because this app uses libraries, I don't recommend restoring this application fully with Titanium Backup. Always use the installer to install. Titanium Backup Pro is effective for restoring "data only".

2) I think browser url redirecting is also problem so I got this application by [MENTION=2842093]julianjm[/MENTION]. Follow the instructions for defaults.

Application in Google Play

3) Again, browsers may also redirect. Dolphin for Android includes default applications in advanced mode with an option for YouTube as default. Try it if you fail; no promises.

4) {New link in post 14} Finally, there are redirects that have to be added to Adaway. To make it easy, I've uploaded my Adaway list as export to import into your Adaway as your list to edit as needed. It also includes some white lists that allow hulu to play.

https://www.androidfilehost.com/?fid=23991606952599772 once downloaded, remove the .txt extension and it should import using Adaway/Your lists/Import lists.

5) {New link in post 14} You'll also need to direct the Adaway to servers to download the the lists for the host file. I've included a link and snapshot of the two that I currently use.

Tap the plus sign and add this line{http://someonewhocares.org/hosts/zero/} (don't include the braces.) Thanks to Dan Pollock at someonewhocares.org for sharing a short host source that's effective.

6) Now just download and build your host file and apply from main screen. Turn on the webserver. If it works as planned, your browser YouTube linked playback should redirect to your YouTube.apk, full screen in landscape mode; use the back arrow to return to previous browser location.

7) Don't forget to reboot as the last step.

This is an ongoing effort using other available sources; if it works for you, thank the appropriate sources. I'll update links within xda if available. There is room for improvement. Please share what works or what worked better fit you.

Note: if any if the links in this post did not direct correctly, the short url director app should fix that if setup correctly.
