AdAway

What AdAway is

AdAway is a free, open source Android app that blocks ads system-wide by using the hosts file. Users can add hosts file sources from providers they trust, set allowlist or blocklist exceptions, and create custom redirect rules. Local VPN mode does not require root access; root support is available with Magisk Systemless Hosts. The project is licensed under GPLv3+. The site lists Android 8 and above for version 5, and Android 4.1 and above for version 4. AdAway is not available on Google Play; the site directs users to install it from F-Droid. The project says bug reports and telemetry are sent only if users opt in. The site notes that the app may not work reliably on mobile networks such as 3G when an APN proxy is set. For ads that remain in Chrome, it advises disabling Chrome’s Data Compression Proxy. Documentation is available through the AdAway Wiki on GitHub, and users can seek support in the XDA thread or file a bug report through GitHub.

Who it suits

AdAway suits Android users who want system-wide ad blocking and control over host sources and rules. It can also suit users who prefer a no-root mode or can use Magisk Systemless Hosts.

Limits

The Free plan costs nothing. The site lists Android 8 and above for v5 and Android 4.1 and above for v4; reliability may be affected on mobile networks such as 3G when an APN proxy is set.

Getting started

1. Visit the AdAway website.
2. Check the listed Android version requirements: Android 8 and above for v5, or Android 4.1 and above for v4.
3. Install AdAway from F-Droid.
4. Choose Local VPN mode to use it without root, or use root support with Magisk Systemless Hosts.
5. Consult the AdAway Wiki on GitHub for documentation.

Verdict

AdAway offers configurable hosts-file ad blocking for Android, with a Local VPN option that does not require root. Installation is through F-Droid, and the listed network and Chrome limitations are worth checking first.
