Quick Start Guide

Get HydraDragonAV Mobile running on your device or emulator in minutes.

Requirements

Requirement Value
Android 8.0 Oreo (API 26) or newer
RAM 4 GB minimum (6 GB recommended)
Storage 2 GB free space (signatures + databases)
Build Host Windows 10/11, Linux, or macOS
JDK 17 or newer
Android SDK API 26+ with NDK

Step 1: Clone the Repository

git clone https://github.com/HydraDragonAntivirus/HydraDragonAV-Mobile.git
cd HydraDragonAV-Mobile

The native engine pulls the custom YARA-X fork (with hydradragon/dex modules) as a git dependency — cargo fetches it automatically on first build, so no --recurse-submodules is needed. The local yara-x/ directory holds the project's rule files, not the engine source.

Step 2: Build the Native Rust Engine

cd hydradragonandroid
build-android.cmd

This compiles libhydradragonandroid.so for all four Android ABIs (arm64-v8a, armeabi-v7a, x86_64, x86) using cargo-ndk and copies the outputs into app/src/main/jniLibs/.

Prerequisites:

  • Rust toolchain with Android targets installed
  • Android NDK (set via ANDROID_NDK_HOME)
  • cargo-ndk installed (cargo install cargo-ndk)

Step 3: Build the Android App

./gradlew assembleDebug

The native .so files are picked up automatically from app/src/main/jniLibs/.

The debug APK will be at app/build/outputs/apk/debug/app-debug.apk.

Step 4: Install & Run

adb install app/build/outputs/apk/debug/app-debug.apk

Required permissions (granted at runtime):

  • Accessibility Service (for DynamicAnalysisService)
  • Notification Listener (optional, for notification spam detection)
  • MediaProjection (for ScreenCaptureService OCR)
  • VPN (for DnsVpnService / Web Shield)

Step 5: Verify Installation

  1. Open HydraDragonAV Mobile — you should see the main dashboard.
  2. Run a Quick Scan — installed apps + Downloads folder.
  3. Check that the GuardService is running (persistent notification).
  4. Verify Accessibility Service is enabled in Settings → Accessibility.

First-Run Configuration

  1. Grant all requested permissions.
  2. Enable DynamicAnalysisService in Accessibility settings.
  3. Optionally enable Web Shield (VPN) for DNS filtering.
  4. Optionally enable ScreenCaptureService for live OCR.
  5. Configure scan file size limit in Settings (default: 500 MB, max: 2048 MB).
