Vector

Overview

Following the cessation of active development on the original LSPosed project, Vector (developed by JingMatrix) emerged as the official, active community continuation of the modern ART hooking runtime for Android.

The Xposed paradigm allows developers to modify the behavior of system components and third-party apps dynamically in memory without decompiling or modifying APK files on disk. Vector implements this capability via Zygisk, injecting into Android’s Zygote process to hook Java methods at the native ART runtime level with minimal overhead and zero global system instability.

Technical Architecture & How It Works

ART Method Hooking with SandHook / Pine

1. Zygisk Initialization: When the Android OS initializes the 64-bit and 32-bit Zygote daemons, Vector’s companion native library (liblspd.so) is injected into the process space.
2. Scope Resolution: Unlike legacy Xposed which hooked every single process on the device (causing heavy system stuttering), Vector queries its local SQLite database (/data/adb/lspd/config.db). Only applications explicitly added to a module’s scope receive hook trampolines.
3. ART Inline Hooking: When target apps load, Vector intercepts class loading via ART runtime hooks. It patches the internal ArtMethod structure in memory, redirecting calls from the target method to the module’s interceptor callbacks (beforeHookedMethod and afterHookedMethod).
4. Isolated Manager Bridge: The management interface communicates with the background daemon via native Unix domain sockets, preventing target apps from detecting the presence of the framework.

Installation & Setup

Step 1: Install the Module

1. Download the latest Vector-vX.zip (Zygisk release) from the repository.
2. Open Magisk, KernelSU, or APatch.
3. Flash the zip from the Modules screen and reboot your device.

Step 2: Install the Vector Manager

1. After rebooting, a notification will appear prompting you to install the Vector Manager APK (or open the embedded web interface).
2. If the APK is not automatically placed in notifications, locate manager.apk inside /data/adb/lspd/ and install it manually.

Step 3: Activating Modules

1. Install any Xposed module APK (e.g., Hide My Applist, CustoMIUIzer, KnoxPatch).
2. Open Vector Manager $\rightarrow$ tap Modules.
3. Toggle the module ON and configure its target Scope (check the specific apps you want the module to modify).
4. Force stop or reboot the target apps to apply changes.
