In previous implementations, proc_monitor checks whether the mount namespace of an app is actually separated from zygote using a list generated at startup. However, for some unknown reason, some devices (e.g. Samsung) has multiple zygote servers running in the background. This means that app processes spawned from the unlisted zygotes are not checked whether the separation is done or not, causing MagiskHide unmount stuffs in the namespace of zygote, and since zygote is the "mother" of all apps, all apps will no longer have root access. Since I'm not sure of the reason why multiple zygotes exists, so instead of checking the namespace against a list, compare the current namespace against the parent process's namespace. This will make sure the namespace is NOT the same as the parent process, which is supposed to be the zygote server.

Building Environment Requirements
- Python 3.5+: run
build.pyscript - Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
- Latest Android SDK: set
ANDROID_HOMEenvironment variable to the path to Android SDK - Android NDK: Install NDK along with SDK (
$ANDROID_HOME/ndk-bundle), or optionally specify a custom pathANDROID_NDK - (Windows Only) Python package Colorama: Install with
pip install colorama, used for ANSI color codes
Building Notes and Instructions
- Building is tested on macOS, Ubuntu, and Windows 10 using the latest stable NDK and NDK r10e. Officially released binaries were built with NDK r10e.
- Set configurations in
config.prop. A sample fileconfig.prop.sampleis provided as an example. - Run
build.pywith argument-hto see the built-in help message. The-hoption also works for each supported actions, e.g../build.py binary -h - By default,
build.pybuild binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (via the--releaseflag), you need a Java Keystore filerelease-key.jksto sign Magisk Manager's APK. For more information, check out Google's Official Documentation. - The SafetyNet extension pack requires the full Magisk Manager as a
compileOnlydependency. Build the release APK, convert it back to Java.classfiles (I use dex2jar), and place the converted JAR undersnet/libsbefore compiling.
