Magisk

Introduction

Magisk is a suite of open source tools for customizing Android, supporting devices higher than Android 4.2 (API 17). It covers the fundamental parts for Android customization: root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt removals etc.

Furthermore, Magisk provides a Systemless Interface to alter the system (or vendor) arbitrarily while the actual partitions stay completely intact. With its systemless nature along with several other hacks, Magisk can almost perfectly hide modifications within userspace. Note that since 2020.3, the CTS check of Google's SafetyNet API will NOT pass.

Bug Reports

Only reports using debug canary builds will be accepted.
Access canary builds by upgrading to either canary Magisk Manager:

For installation issues, upload both boot image and install logs.
For Magisk issues, upload boot logcat or dmesg.
For Magisk Manager crashes, record and upload the logcat when the crash occurs.

Building Environment Requirements

Python 3: run build.py script
Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
Latest Android SDK: set ANDROID_HOME environment variable to the path to Android SDK
Android NDK: Install NDK along with SDK ($ANDROID_HOME/ndk-bundle), or optionally specify a custom path ANDROID_NDK_HOME
(Windows Only) Python package Colorama: Install with pip install colorama, used for ANSI color codes

Building Notes and Instructions

Clone sources with submodules: git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git
Building is supported on macOS, Linux, and Windows. Official releases are built and tested with FrankeNDK; point ANDROID_NDK_HOME to FrankeNDK if you want to use it for compiling.
Set configurations in config.prop. A sample file config.prop.sample is provided as an example.
Run build.py with argument -h to see the built-in help message. The -h option also works for each supported actions, e.g. ./build.py binary -h
By default, build.py build binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (via the -r, --release flag), you need a Java Keystore file release-key.jks (only JKS format is supported) to sign APKs and zips. For more information, check out Google's Official Documentation.
