[VGib]

Environment

Adblock plus Version 1.2.1 build #347

How to reproduce

install adblock plus. Install the proxy for the wifi or the 4G.
No ads are block.

Observed behaviour

No ads are block

Expected behaviour

Ads are block

As no one open the bug, i'm openning it. Please let me know if a workaround or new version is available

Works fine for me with a Nexus 7 and Lollipop with the same ABP version.

ABP does not work on a non-rooted nexus, of any kind, running lollipop. The software 'runs' but it does not block adds at all. Has a constant state of 'waiting for traffic on port 2020'. You will occasionally get it bugged where it claims it's blocking traffic but it is not.

The problem is that the iptables in addblock are incorrect for lollipop:

This is an easy fix, just recompile iptables with PIE. Should take 5 mins, please issue an update for lollipop.

(Rooted users are already doing this to fix their own devices)

@rjeschke: Can you please look into this any time soon?

[fhd]

Yeah, I'll look into it. I've got some doubts this has anything to do with iptables though, since we don't even run it on non-rooted devices.

Looks like the real issue here is that android.net.ProxyProperties is gone (apparerently replaced by ​ProxyInfo), so merely an API change, that appears to be the only problem in ABP 1.2.1. In the latest devbuild, there's also an issue with the new proxy configurators, most likely that's #1498, us checking for root access.

I don't think we want to wait for 1.3 with this, so I'll work on a patch for 1.2.1 tomorrow, that'll allow us to do a fix release making things work on Lollipop again.

Thanks

Found some time to look into this properly now, and I cannot reproduce the problem.

I was chasing the wrong rabbit regarding ProxyProperties above - we recover from those exceptions just fine, works just fine on a Nexus 7 running 5.0.1 here.

The same goes for the devbuild, 1.3.347 works just fine for me.

Philip, you said you were able to reproduce this, right? How?

[fhd]

VGib, could you check what it says under "Filter subscription" in the ABP UI? Does it say "not loaded"? Does updating manually work?

Hi,

I can confirm the problem on a Nexus 4. Since the upgrade to Lollipop adblock stopped working. It still runs but it never updates its block list. Therefore some ads are still blocked but new ones not.

If I update manually then adblock crashes.

[VGib]

After 5.0.1 update and last adblock plus update; this seems to work for wifi.
But it still daesn't work for 4G internet.

I have in Filter subscription subscription: Liste FR + EasyList. (I'm french)

This was working with Android 4.4 KitKat and 4G.

I visit some of this website to check: www.mangareader.net or www.leparisien.fr

[philll]

Filter lists couldn't be downloaded when I tested with a Nexus 4 and lollipop. I attached the log file​. With a Nexus 7 on lollipop, updating the filter lists manually after the failed download reliably crashed Adblock Plus. Also attached that Nexus 7 log file​.

I just upgraded from KitKit to Lollipop on my HTC One M8.

ABP was a little flaky under KK (Internet connections for valid apps like FB and linkedin would randomly be unavailable), but ABP does not work at all on my device.

Following has been identified (before I uninstalled it):

1. The hide icon does nothing...icon is still visible
2. No ads are blocked
3. Cannot update lists...ABP just crashes everytime.

ABP worked great for me on my HTC Sensation (ICS), and it would be great see have it working again on my One.

Thx

I have the same problem on the Galaxy s5 (unrooted.)
After updating to Android Lollipop(5.0) ABP says "waiting for traffic on port 2020" even though my settings are properly configured. I tried reinstalling with the dev-build for Android (354) and have had no success. I can update the Easylist w/o crashing on 354, however.

[rjeschke]

I ran some tests using the latest dev-build on some Android 5 devices:

• started ABP
• updated subscription
• click on 'Hide icon'
• Open Chrome, browse to ​http://kvraudio.com to see if ads are blocked

These are the results:

Device           : Android : Blocks : Update :  Icon
.................:.........:........:........:........
Motorola Nexus 6 :  5.0.1  :  yes   :  yes   : partly
LG Nexus 5       :  5.0.1  :  yes   :  yes   : partly
HTC Nexus 9      :  5.0    :  yes   :  yes   : partly

partly in the icon column means, invisible icon but on the wrong position (not right-most), this is a known problem

So far I can not reproduce the bug that prevents ads from getting blocked. There is, though, an issue with the icon, as it only gets hidden (as it seems) when it gets updated to 'Ads are blocked on ...'. Will have a look into this soon.

Still, using our test devices I am not able to verify that ads are not blocked on Android 5. So we either need a S5 and a M8 here, or the log output from external devices.

Another thing: we will have to examine the 'Waiting for traffic' notification's behaviour again. It is possible that it gets fired on every start now, if the proxy could not be set from within ABP. Still, the notification should vanish after it really receives 'traffic', i.e. a request.

From my side, as I can not reproduce any serious bugs, and the rest is more or less cosmetics, we should really reduce the priority again to P2, except anybody is able to prove that build 354 still fails to block ads or fails on updating.

[philll]

We simply cannot reproduce this so far and can prove that this doesn't affect all lollipop users. Getting more debug output into our app is the best we can do for now on our end, but that is another story.

[Sasqwatch]

Pardon my ignorance, but is Adblock Plus supposed to stop ads in games? Things such as Candy Crush? The reason I ask is before the 5.0.1 update on my HTC M8 (sim free) AdB would update subscription lists and stop the ads. Now it does neither. On trying to update lists, the app crashes and then restarts without loading the lists.

Replying to xxKumquat:

I have the same problem on the Galaxy s5 (unrooted.)
After updating to Android Lollipop(5.0) ABP says "waiting for traffic on port 2020" even though my settings are properly configured. I tried reinstalling with the dev-build for Android (354) and have had no success. I can update the Easylist w/o crashing on 354, however.

Retested with 355 development build. Adds are now blocked, and the proxy settings ARE detected by ABP. There is, however a confliction between the "Mobiwol no root firewall" app and ABP that was not present pre-lollipop. With Mobiwol, ABP still has the same problems stated previously.

[rjeschke]

@xxKumquat This can still be a problem of the Mobiwol firewall and might need a fix on their side, as it is using a VPN. We will try to debug these issues and see if we can do anything about this.

@Sasqwatch We are terribly sorry, but ABP does update subscriptions and block ads without crashing on our test devices. It would be really helpful if anybody could provide the logcat output from such a crash (using the latest development build -> build 354+).

[Sasqwatch]

Version 1.2.1 Build 355 works fine now, blocks ads and loads subscription.
