Build Instructions

Requirements

Android Studio Ladybug or newer
JDK 17 or higher
Android SDK 36 (min SDK 24)
(Optional - only needed if modifying Go tunnel) Go 1.23+ and gomobile

Steps

[!TIP] Historical versions of the Go binary (tunnel.aar) were committed in the past before being moved to GitHub Releases. To avoid downloading ~1.2GB of old binaries, use blobless clone (--filter=blob:limit=1m) to download only ~20MB.

Clone the repository:
```
git clone --filter=blob:limit=1m https://github.com/pass-with-high-score/blockads-android.git
cd blockads-android
```
(Or for a shallow clone: git clone --depth=1 https://github.com/pass-with-high-score/blockads-android.git)
(Optional) Build the Go tunnel AAR/JAR from source (with Android 15 16KB page size support):
```
./scripts/build_tunnel.sh
# Or
./gradlew -Ptunnel.source=local buildGoTunnel
```
Note: This is completely optional. Gradle automatically resolves a prebuilt, checksum-pinned tunnel.aar from GitHub Releases by default. You do not need Go or NDK unless you are modifying Go code in tunnel/. See docs/TUNNEL.md.
Open the project in Android Studio
Sync Gradle and run the app on a device or emulator

Build from command line:

./gradlew assembleDebug
./gradlew bundleRelease   # requires signing key

How It Works

BlockAds routes DNS queries locally either through a VpnService (Vpn Mode) or via iptables redirection (Root Proxy Mode). These queries are matched against loaded filter lists using a memory-efficient Trie data structure. Matching queries are blocked locally, while all other traffic passes through normally — no data leaves your device.

When HTTPS Filtering is enabled, a userspace TCP/IP stack (gVisor netstack via tun2socks) terminates each TCP/UDP flow in Go, looks up the owning app UID via Android's ConnectivityManager.getConnectionOwnerUid(), and only MITMs flows from selected browsers. Cert-pinned apps and the 284-domain curated passthrough list bypass MITM cleanly. Cosmetic CSS rules and EasyList ##+js(…) / AdGuard #%#//scriptlet(…) scriptlets are injected into HTML responses via a tiny in-memory local asset host.
