Modern Android Multi-App Virtual Container with True Sandbox Isolation & Anti-Detection

Run unlimited parallel instances & multiple apps per container with isolated filesystem, accounts, and anti-detection — no root required.

📖 Overview

Renjana is a high-performance Android virtual container engineered to clone, sandbox, and run multiple applications simultaneously. Each instance container operates with fully isolated storage directories, independent Google accounts, unique hardware fingerprints, and dedicated subprocess stacks (:p0 – :p9), without requiring device root or system modifications.

[!NOTE] Powered by the Pine dynamic instrumentation framework and AndroidX Jetpack Compose Material 3 design system.

✨ Key Features

Feature	Description
🗂️ Multi-Instance Containers	Clone any installed application or APK into independent, isolated virtual containers.
📦 Multi-App Per Container	Host and launch multiple distinct applications inside a single container instance.
🔑 Independent Google Accounts	Assign and virtualize different Google accounts per container instance.
🔒 True Sandbox Data Isolation	Dedicated `/instances/<id>/packages/<package>/` paths for databases, shared prefs, cache, and DEX cache.
🧩 Split APK (App Bundle) Support	Seamless dynamic loading for modern Google Play multi-split APK architectures.
🛡️ Anti-Detection & Fingerprint Spoofing	Randomize Android ID, IMEI, Build props, signature spoofing, and evasion checks.
🌱 Non-Root Operation	Full user-space virtualization using lightweight ART runtime instrumentation.
