🧑‍💻 Technical Overview

How it started?

After encountering limitations with the V2ray client’s filtering capabilities In China and Iran and realizing the need for a more efficient and portable solution, this application was created to enable users to perform scanning operations directly on their Android devices. With the ability to resume scans and a user-friendly interface, it provides a convenient alternative to traditional computer-based scanning.

Structure and Architecture

This application was developed using Kotlin programming language and follows the Model-View-Intent ( MVI) architecture pattern. The application also leverages the power of Compose, the modern Android UI toolkit, for building the user interface instead of the traditional XML layout approach. Additionally, C++ was used to disable fdsan to avoid fatal error for native third-party library.

Dependencies

Design

I designed the logo using AdobeXD and incorporated its color scheme throughout the application.  Note: Design is accessible in art/logo.xdfor AdobeXD

Build and Run

To Build application you need google-services.json file in app directory, you can get it from firebase console.Also you need NDK for build native library.

Note: You can set default Fronting Url in local.properties file like:

fronting_address = "your address without https"

⚒️ Upcoming Features
