precisely why i asked to whitelist youtube. my history on different devices don't get synced, and i get suggested vidoes i already watched etc.

cheers y'all!
You will get video's you watched suggested again. Its a part of YouTube AI. I would guess the logic as, if you were interested once, you may watch it again (possibky by accident), and its simply another opportunity for google to serve you ads.

Hi all,

Frankly, I don't know if you could block ads in Chrome while using AdAway in VPN mode

A year+ ago I had two phones, rooted and not-rooted one, both with AdAway (one hosts, the other VPN mode), both running Chrome with Lite mode off.
On the rooted phone, AdAway blocked ads in Chrome and 'everwhere' (of course, not in e.g. YT).
On the not rooted phone ads were blocked 'everywhere' but I never managed to let AdAway block them in Chrome

Nowadays I have only the rooted phone and AdAway still perfectly blocks me ads in Chrome and 'elswhere'

Btw, Chrome for me is essential, primarily because of the built-in translator - sometimes, if I want I even read in Japanese, Chinese, Arabian, whatever


If you have Android 9 or higher, disable AdAway and enable Private DNS in your native Settings, and for DNS provider put e g: dns.adguard.com

I don't recall anymore but I think Chrome will also bypass that VPN and you will still see the ads in Chrome (that Private DNS uses VPN to the configured DNS server which blocks the sites pushing ads by not resolving their DNS names)

IMHO, only some pretty old versions of Chrome can be enforced to go through your VPN (AdAway or Private DNS), and that's why you cannot block ads in Chrome, with AdAway in the non-root mode
I can successfully block ads on Chrome if lite mode is not enabled.
I just set up an emulator on Android 11 with Play API, install AdAway, block a custom site, apply and check if it is blocked on Chrome. It is.

Not I did not set a Google account so lite mode was not enabled.

I am no longer using AdAway. one of the reasons is that it isnt so good at looooong blocking lists.
Did you move to another app? if so, which one?
I could have a look to check how it handles the hosts merge better but it is challenging subject. I already released several implementation of the subject and they is currently two strategies running in the app...

The solution I have is to do the merging client side. So you can set as many as host files you want without impacting your device resources but (there is always a but) I should charge for this feature.
I don't know how much but moving the processing power from all your devices to one place won't be free from the cloud provider that will run it ^^'

OnePlus 9
AdAway blocks Spotify?!
Recording dns request and allow them didn't solve the problem.
Any ideas?
With my old phone AdAway and Spotify worked well. Only with new phone I have the problems.

no not the notification, but the app itself.
I don't have the app on all the time, especially at home, but i notice that the app has turned itself on, without any interaction from myself
Preferences, Updates, disable all automatic updates

However, non-root must be running all the time its VPN service, monitor media reconnections - search for the non-root version and some reconnection issues already reported and discussed in the thread

Thanks for the info.
There are some issues here. First database should answer. Then, error should not leak the database password (that I just changed).

I will investigate what happened for those two problem and revert the whole hosting to ensure nothing was altered... (better safe than sorry).
Could you trim the error message from your post? It won't prevent Google from indexing it or remove it from the Internet history but better removing it. Thanks.

Thanks for the quick edit!

On my side, my hosting provider just changed my database domain name 15 mins ago, breaking most of my services...
And I also found an error in the debug settings on the AdAway backend that I obviously did not test, leading to display error context in production.

Everything should be back in order now.

Good afternoon @PerfectSlayer

First of all thank you for your work and time.

I wanted to report a bug in Adaway. It turns out that if you update, add lists of hosts, etc... With data, normal wiffi there is no problem. But if you use 5 ghz wiffi. Adaway goes crazy. Meaning:

On the main screen where you get the number of sources you have installed, and the ones to update. Well, you see how the number of installed lists decreases, and even says 0 installed fonts. Again where this the lists of hosts. To some of them it says installed a few minutes ago, to another one updated for few minutes. Or simply it does not load the total. That is to say for example source Steven and it leaves a number for example 250k and this number removes it.

I have already tried rebooting, reinstalling Adaway and backup, Adaway without backup and putting one by one the lists. Clearing cache, etc... And always the same.

And it is not a failure of the mobile or wifi. Because everything goes fine on the wiffi 5 ghz. That is browser without problems, fdroid without problems, etc... I tested on a Nexus 6p with lineageos and Magisk in its latest version. And on Samsung S9+ also with lineageos magisk updated. And Adaway in its latest version 5.8.0 . And this before I did not do that I realize. And I have not changed anything on the phone

I would also like to ask you if it would be possible to add Adaway. An option that after updating the sources of the host lists, are updated. Adaway reboot the mobile. Or a warning if you want to restart the phone or not. As it happened in versions 4. I comment it because I see that Adaway processes better the updates and changes after restarting the mobile.

Thank you very much for your time and help.

Best regards

sorry but I don't know English.
I have installed Adaway 5.8.0-210808 on POCO F3 ROM Xiaomi.eu when I start the app and get to the sync it says "Sync failed: Unable to install new file". I understand that I need to change some settings but I don't know exactly what and where to find them.
Can someone explain to me how to do this? Thank you.

I am getting ERR_CONNECTION_REFUSED for websites that are part of my Allowed or Redirected lists. Specifically, I am trying to add the ad services sites used on SlickDeals. Here is a paste of my backup JSON that I try to restore. I see that you can only have them in Allowed or Redirected. I have tried both methods, but I still get the error when browsing.

Specifically, in the case of tkqlhce.com, I see that it is part of the Blocked list. Is that causing a conflict? Can I remove it somehow?

Is there something else that I need to do?

    Good morning,
    Has the disconnection bug when transferring data to WiFi on non-rooted smartphones been fixed?.


    Not yet. It becomes part of my morning routine. Grabbing my device, checking the state of the device, capturing a logcat, scrolling the log to check what happened, looking for system errors, wandering into android platform documentation… Not an easy task!

    I fixed a lot of issues during the whole VPN rewrite. The last one dates from this weekend.
    I found the Android Backup Service was killing the VPN foreground service as part as the backup process.
    So I rewrote the backup solution. Good news backups will now works properly (the backup data was exceeding the allowed quota so the backup was never uploading to Google services...) for both rooted and non-rooted users.

    See the commit for all the details.

    Strictly speaking of the network switch bug, the new VPN works pretty well on my side. Again, it will improve from user feedback but I use it on my daily driver without issue (2/3/4/5g, personal wifi, entreprise wifi with multiple hotspots). If you are developer yourself, don't hesitate to built the feature/vpn branch and report how it works for you!
    why can't i import this list to the app?
    Because it isn't a host file. Host files are formatted google.com
    Please Add features Block ads with option Apps installed 🙏 thx
    When using VPN mode, you can control for which apps blocking will apply (by default, it will block for all the apps installed).
    However, it works only for blocking through DNS - if some apps use proprietary methods to push ads through their content channel (like YouTube), you must use special solutions (like Vanced YT) to block their ads

    In the hosts mode, AdAway can only give the changed hosts file to the system. After that, system applies thtat hosts file to all apps and AdAway cannot control to which apps the changed hosts file would be applied or not

    Finally, by choosing hosts sources, user controls which types of 'ads' will be blocked. By searching on tthe Net, you can find hosts sources that block only commercial apps, and/or analytics, porn, etc

    All that (theory, how VPN mode works, how hosts file works) has been extensively discussed earlier here and one can also google and read/learn about, hence it makes no sense to write about all that once again (how the given two mode work and what is possible and how/why or not)
    why can't i import this list to the app?
    NINJA'd!: its for AdGuard not AdAway. The format is completely different between the two, and the URL itself tells you its for AdGuard.
    After upgrading to the latest version of chrome, adway cannot block ads.
    After downgrading to use version 87.0.4280.141, adaway can block ads.
    Regularly updting Chrome, currently on 96.0.4664.104, and ads are always blocked

    AdAway root/hosts version, and Lite mode is disabled in Chrome

    AdAway is an open source ad blocker for Android using the hosts file.

    Google Play Store notice:

    According the Google Play Developer Policy, especially the "Device and Network Abuse" section, ad blocker like AdAway violates the "Apps that block or interfere with another app displaying ads." rule and can't be distributed on distributed on the Play Store.
    As Free and Open Source Software, AdAway is available from F-Droid Store or this XDA thread :good:


    This application requires Android 8 or above and does no more require root.

    For older Android versions, a rooted device is required.


    If you don't want to read each announce post of this thread, you can:


    Stable versions are available on F-Droid Store and below:

    Beta versions are available on XDA development thread only:

    AdAway 5.0.10

    Problem? Read this:

    * If you use Chrome and still see ads on web pages, remember to disable the "data saver" or "reduced data usage" browser option
    * Check your APN settings for any proxy, the proxy itself could be allowing ads. Disable the proxy.
    * After you install or make any change to AdAway, you must reboot for those changes to take effect
    * If you are still having issues please read and understand all the info in the wiki before asking for help here

    Otherwise, this is the right thread to discuss about it or file a bug report here.

    Hi all,

    A new year is coming and I wish you all to have nice holidays :victory:

    Just few words about this ending year. There was about 12 releases in 2019 which brings you a new UI, a lot of bug fixes, Android 10 support, Gist and GitLab hosting support and better Magisk support.
    All of this is possible thanks to the community to help users to discover the app, learn how to use it and report any new bug and also your moral, nice words and thanks you can send to me, and financial support.
    Thanks a lot for all donators, GitHub sponsor and the Pixel 2 you sent me to test Android 10 support.

    For the next year, I hope to release the next version (V5), at least in beta to start. It's been 9 months since its first lines of code and things are working quite nicely.
    It aims to make the app simpler to use for the main use cases, support rooted and non rooted devices and remove old hacks/workaround which are no more needed on recent setups.

    But before this big next update, I still have time to fix current issue with a new release :p

    • Fix GitLab hosting support (commit date parsing failed)
    • Translation update


    Special thanks to @gallegonovato for its helpful bug report and @Vankog for translation update.


    AdAway 4.3.2 on AndroidFileHost (md5: 78fde09a0e92044c45e901bb1cec8e2e)
    Hi all,

    Long time no see! It's been more than two months since the last update.
    I can't say I was not active on the project as I start working on a new version (5.x.y) as a side project.
    I won't share the source code yet as it is not ready at all and I don't want to give an ETA but this new version targets the following goals:
    • 1. Revamp the UI
    • 2. Clean up old support
    • 3. Address one of the main drawback of the app

    1. The card based UI does not feel right. Welcome card takes too much space, update button / status has a lot of critic. I guess I can do better.
    I started a new simpler and lighter design which provide the most useful information on home screen and all main actions to trigger in one tap (no more burger menu).
    It is still under heavy development but I hopefully get a friend onboard, specialized in graphics and design, to help me :highfive:

    2. In order to simplify the development, I clean up the app and remove support for old features.
    I bump target SDK version so I finally get Java 8 language feature (it was released 5y ago…) and move to topjohnwu root library (instead of home made one). It means systemless support is now handled by Magisk and other root solutions will still work.

    3. Think of what prevent most of users to use AdAway? Now it's gone!
    It's not gone forever. It's still here but there will be a fallback to workaround it.
    I won't tell more until the first public beta but I guess you get the point :fingers-crossed:

    In the meanwhile, here is a new version!


    Is anyone using a hosts list hosted on Gitlab? It keeps showing "Unknown update status".
    GitLab, like GitHub do not set LastModified HTTP header so update status is not supported... yet!

    • Add Gist and GitLab hosting support for hosts file
    • Add option to set default IPv6 redirection
    • Improve reboot command
    • Improve UI for overlays
    • Update translations


    Special thanks to @MSF Jarvis and ralayax for theirs contributions and @andy356 for its helpful bug report.


    AdAway 4.2.5 on AndroidFileHost (md5: ab81225745afaaa7646024109de299c0)
    Hi all,


    Hmm, not working for me for this URL, v4.1.0 shows something like not updated in -360 days (some large negative value). Can you please see if you can reproduce?
    It works well here. I failed to reproduce as I change the HTTP client library and how I use it.
    But update date for the source you link definitely works now.

    All the F-Droid apps I know of have manual push updates to the store.

    Isn't automatic build basically for nightlies?
    Not really. You could choose a lot of different mode.
    For example, F-Droid server watches AdAway GitHub repository to find tags which match a specific versioning pattern.

    I exist still... do you know what i have to do to transfer ownership? if i edit project it doesn't let me change the primary author so i assume i have to PM some higher up to make this happen?
    Thank you so much! :highfive:

    This is now done, @PerfectSlayer is the OP of this thread.
    Thank you too!

    AdAway 4.2.0 on AndroidFileHost (md5: 023169e7c345ef7297095793024f8478)
    Hi all,

    I talked enough about it the past weeks and here it is: the first beta for the next version of AdAway.
    As you know, the main feature is the removal of root requirement but it also comes with a lot of improvements like an easier to use UI, a builtin updater, new cache and databases to improve reliability or even a quick pause/resume adblocking button that 3rd party apps can control.

    It took me literally a year and 330+ commits to build it (the first commit of this branch was April the 7th) and I hope it will be worth it.
    It should allow the app to be viable in the future with root being more and more difficult to achieve at each new Android release and Google hardening SafetyNet checks.

    I will try to answer to the most expected questions here so you still can post a link to this FAQ later to lost users.


    Does this version replace the v4.x versions?
    No. This is still a preview version and does not replace the stable one.
    It is available to test it and report issues and feedback before being promoted to stable.

    Can I upgrade and revert safely?
    Yes. Both v4 and v5 use the same settings export format.

    Why does this version targets Android 8+ Oreo only?
    Like the v4, v5 is expected to offer support for latest devices.
    Android 8 and above represent more than 60% of device distribution and will grew through time.
    If you use an older device, root solutions work very well and v4 is here for you (like v2 and v3 stayed for legacy devices).

    How the hell does it work without root?
    This version provides two adblocking methods: the usual root one using hosts file and a new one using local VPN.
    The VPN solution allows to filter and alter connections of your devices without root access.

    Is using a VPN safe?
    In the case of AdAway, yes. It uses VPN API but does not connect to a VPN server.
    In the case of VPN client app, it depends.
    To give you more details, a VPN client app uses the VPN API to create a virtual network interface on your device and redirect all your traffic into it.
    If you imaginge the VPN like a pipe (the right word is tunnel), client VPN app outputs all your traffic on a VPN server which is able to check what you are doing on the Internet.
    With AdAway, your network is not redirected to a VPN server but your device internet connection (same as no VPN). VPN API is only used to get traffic into it to break the connections to ad servers.

    Is VPN use battery?
    Yes, like everything you do on device.
    Witouth root, a VPN service will be running permanently to filter your traffic.
    Good news is it will only filter DNS traffic. Not all traffic is redirected into it so it won't be as expensive as you can fear.

    Did you come up with this idea alone?
    Absolutely not! I spent a lot of hours trying to find altenatives to hosts based adblocking (like routes or private DNS). But nothing was better than VPN based adblocking.
    So we (MrRobinson and I) approched Julian Klode, developer of DNS66 more than three years ago to see if we can merge our apps. It wasn't that easy as we don't develop our apps the same way so I ended up by integrating the DNS66 adblocking method into AdAway. It is fine for Julian, his app is Open Source and he himself built it from the core code of AdBuster app (an VPN based adblocking app).

    Should we stop using DNS66 for AdAway?
    Not at all. DNS66 is a great app and provides some features that AdAway doesn't have (yet?), like DNS settings.
    DNS66 is a great app, keep using it if you like it!
    If both apps used the same adblocking method a year ago when I start this version, I keep adding feature to the VPN adblocking method and most of them won't be in DNS66.
    If Julian ports them back to DNS66, it's great if it can help his app and users!

    Is it me or the app put on weight?
    Yes, the app significantly grew due to new libraries like VPN related ones and Android Jetpack.
    It also stores more data on device: a http cache, a host database, a hosts copy, etc...
    I think 15~20mo of storage is still fine.
