Dexor

Unified DEX2OAT Runtime & Ahead-Of-Time (AOT) Bytecode Manager for Android

---

What is Dexor?

Dexor is a modern, non-root Android utility that puts you in control of how your applications are compiled and executed by the Android Runtime (ART).

By leveraging Shizuku to interface safely with Android's internal compilation service (cmd package compile), Dexor lets you trigger on-demand and batch Ahead-Of-Time (AOT) compilation without requiring root access.

How it Works (Why You Need It)

When Android apps are installed or updated, they consist of Dalvik Executable (DEX) bytecode. To execute this code quickly, the Android Runtime (dex2oat) compiles bytecode into native machine code.

• The Default Behavior: Normally, Android only runs full AOT compilation during idle maintenance—when your device is connected to a charger, at 100% battery, and completely untouched overnight (bg-dexopt). Otherwise, apps run through Just-In-Time (JIT) interpretation, leading to initial launch delays and micro-stutters while code compiles on the fly.
• The Dexor Solution: Dexor unlocks immediate, granular control over this process. You can force-compile demanding apps or games to speed mode to eliminate JIT warmups, or revert unneeded apps to verify mode to reclaim gigabytes of storage space—all with a single tap.

Key Features

• Elevated AOT Compilation Without Root: Utilizes Shizuku IPC to safely execute native cmd package compile commands without modifying system partitions.
• Deep Dexopt State Inspection: Inspect real-time compiler filters (speed, space, verify, everything), compilation trigger reasons (cmdline, install, bg-dexopt), and APK path details for every installed package.
• Batch Optimization Pipeline: Select multiple apps across user and system categories to compile sequentially, featuring live progress indicators and estimated time calculations.
• Instant Search & Multi-Criteria Filtering: Filter between User and System apps, and sort instantly by App Name, DEX Status, or Package Source.
• 100% Offline & Private: android.permission.INTERNET is completely absent from the manifest. Dexor does not collect telemetry, track usage, or display advertisements.
• Lightweight & High Performance: Built with Jetpack Compose, an asynchronous coroutine pipeline, in-memory Room caching, and compressed to just 3.16 MB with R8 full minification.

Compilation Modes

Dexor exposes Android's native compilation filters so you can balance runtime execution performance with device storage:

Mode	Filter Flag	How It Works	Storage Impact	Best Used For
Speed	speed	Force-compiles all accessible bytecode methods into native machine code. Eliminates JIT compilation stutters.	High	Games, daily drivers, and performance-sensitive apps.
Space	space	Compiles core application initialization and entry points only.	Low–Medium	General apps where saving disk space is prioritized over peak velocity.
Verify	verify	Validates DEX bytecode structure without generating native machine code. Reverts the app to the raw JIT interpreter.	Minimum	Reclaiming maximum storage space from rarely used apps.
Everything	everything	Exhaustively compiles every method and resolves all class references unconditionally.	Maximum	Complete native execution across entire APK codebase.

Requirements

• Android Version: Android 9.0 to Android 15 (API 28 – 35)
• Privilege Manager: Shizuku (v13.1.5 or newer) running via Wireless Debugging, ADB, or Root

Note

Shizuku is required to grant Dexor the elevated permissions needed to trigger package compilation. If Shizuku is inactive, Dexor operates in a read-only inspection mode. Visit the Shizuku Setup Guide for setup instructions.

Installation

1. Download the latest app-release.apk from GitHub Releases.
2. Install the APK on your Android device.
3. Ensure Shizuku is running, then launch Dexor and grant permission when prompted.

Privacy & Security

Dexor adheres strictly to privacy-first Android development:

• Zero Network Permissions: No INTERNET permission requested. Network access is physically impossible.
