SimpleXray

SimpleXray is a high-performance proxy client for Android, built upon the robust Xray-core (@XTLS/Xray-core).

It features an innovative approach: directly executing the official Xray-core binary, unlike traditional JNI methods. This method isolates core logic from the app layer, boosting stability and maximizing Xray-core's native performance. SimpleXray aims to provide a stable and efficient network experience.

Key Features

• Enhanced Stability: By running Xray-core as an independent child process, SimpleXray avoids JNI complexities, potential memory issues, and app crashes linked to core library failures. This isolation significantly improves reliability.
• High Performance: Leverages Xray-core's native speed and integrates @heiher/hev-socks5-tunnel for efficient Tun2socks, ensuring low latency and high throughput.
• User-Friendly: Offers a clean, intuitive UI and simplified setup, making it easy for users to configure and manage connections.

Unique Technical Approach

Most Xray-core Android clients use JNI to call a compiled .so library. While easy to integrate, this can cause stability issues like performance overhead, cross-language complexity, and app crashes if the core library fails.

SimpleXray's core difference is how it starts and manages the proxy:

On installation/update, the embedded Xray-core binary (as libxray.so) is extracted. When connecting, the app uses standard Android APIs to run this binary as a separate child process, not via JNI calls. Communication happens via defined Inter-Process Communication (IPC).

This design preserves the original Xray-core binary's stability and performance while physically isolating the core process from the main app, enhancing reliability and security.

Data Files (geoip.dat / geosite.dat)

The project includes a simplified version with basic rules ("geoip:private", "geoip:cn", "geosite:gfw") from @lhear/v2ray-rules-dat.

Quick Start

1. Requirement: Android 10 or higher.
2. Get App: Download the APK from the Release Page or get it from F-Droid.
3. Install: Install the APK on your device.
4. Configure: Launch the app, import or manually add server details.
5. Connect: Select a config and tap connect.

Build Guide (Developers)

1. Environment: Install Android Studio and configure the Android SDK.
2. Get Code: Clone the repo and submodules:

   git clone --recursive https://github.com/lhear/SimpleXray
   

3. Import: Open the project in Android Studio.
4. Integrate Core: Place the Xray-core binary (libxray.so) for your target architecture in app/src/main/jniLibs/[architecture directory]. E.g., app/src/main/jniLibs/arm64-v8a/libxray.so.
5. Add Data Files: Place geoip.dat and geosite.dat files into the app/src/main/assets/ directory. These are required for routing.
6. Build: Sync Gradle and run the build task.
