Block ads system-wide on Android with AdAway using hosts-file or VPN-based filtering, without root access.
TBlock
Block ads across a system with TBlock, an open-source Python tool that uses the hosts file.
About TBlock
TBlock is a systemwide ad blocker that uses the hosts file to block ads and trackers across a computer, including web browsers and other apps. It is written in Python and can be used through command-line tools or a graphical application. It includes a filter list registry for subscribing to popular lists, and lists are updated automatically when they reach their expiry date. Blocking is not limited to advertising. According to the homepage, users choose what to block, which can include trackers, malicious web pages, and adult content.
The homepage states that the developers never collect data about users. It also notes that TBlock downloads its blocklists from third-party servers that may track users during that process. Bug reports require additional information that the user must provide manually. The project is maintained by a nonprofit community and developed by volunteers in their free time.
