use https://github.com/xBZZZZ/android_7.1.1_x86_64_libhoudini_magisk because it works with enforcing selinux

how to install libhoudini to Android Studio Android 7.1.1 (Nougat) Intel x86 Atom_64 System Image

Note: you will need to replace paths in commands in this tuturial.

ramdisk.img, system.img are located inside ~/Android/Sdk/system-images/android-25/default/x86_64 (25 is API level of Android 7.1.1, you can see it in SDK Manager).

You will need fakeroot, fuse2fs, cpio, gzip, find, fusermount3, unzip. If you are using Ubuntu you can install these using apt:

pkexec apt install fakeroot fuse2fs cpio gzip findutils fuse3 unzip

step 1: get fake root shell fakeroot step 2: patch system.img Note: system.img is an ext4 file system image. step 2.1: download houdini Download houdini_7.1.1a_y.49564.zip from https://github.com/Rprop/libhoudini/releases/tag/v7.1.1a_y.49564/. I downloaded houdini_7.1.1a_y.49564.zip to /tmp/houdini_7.1.1a_y.49564.zip. step 2.2: mount system.img I mounted system.img to /tmp/system.img_mount. mkdir /tmp/system.img_mount fuse2fs -o fakeroot \ ~/Android/Sdk/system-images/android-25/default/x86_64/system.img \ /tmp/system.img_mount Note: -o fakeroot is needed to bypass permissions of directories and files inside system.img. step 2.3: extract houdini_7.1.1a_y.49564.zip to system.img mountpoint unzip /tmp/houdini_7.1.1a_y.49564.zip -x README.txt -d /tmp/system.img_mount Note: -x README.txt is needed to not extract README.txt file. step 2.4: make executables executable chmod +x \ /tmp/system.img_mount/bin/enable_nativebridge \ /tmp/system.img_mount/bin/houdini \ /tmp/system.img_mount/lib/arm/houdini step 2.5: edit {system.img mountpoint}/build.prop I used nano but you can use any other text editor. nano /tmp/system.img_mount/build.prop Do these edits: find line replace with ro.product.cpu.abilist=x86_64,x86 ro.product.cpu.abilist=x86_64,x86,armeabi-v7a,armeabi ro.product.cpu.abilist32=x86 ro.product.cpu.abilist32=x86,armeabi-v7a,armeabi add to end of file: ro.dalvik.vm.isa.arm=x86 ro.enable.native.bridge.exec=1 Save and exit. step 2.6: unmount system.img cd / fusermount3 -u /tmp/system.img_mount Note: cd / to avoid current working directory inside /tmp/system.img_mount. Note: ignore the ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored. error. step 3: patch ramdisk.img Note: ramdisk.img is a gzipped cpio (New ASCII Format) archive. step 3.1: extract ramdisk.img I extracted ramdisk.img to /tmp/ramdisk.img_extracted. mkdir /tmp/ramdisk.img_extracted gzip -cd ~/Android/Sdk/system-images/android-25/default/x86_64/ramdisk.img | cpio --no-absolute-filenames -iH newc -D /tmp/ramdisk.img_extracted step 3.2: edit {ramdisk.img extract dir}/default.prop I used nano but you can use any other text editor. nano /tmp/ramdisk.img_extracted/default.prop Do these edits: find line replace with ro.dalvik.vm.native.bridge=0 ro.dalvik.vm.native.bridge=libhoudini.so Save and exit. step 3.3: rearchive ramdisk.img cd /tmp/ramdisk.img_extracted find -print0 | cpio -o0H newc | gzip -c9 > ~/Android/Sdk/system-images/android-25/default/x86_64/ramdisk.img step 4 (optional): cleanup cd / rmdir /tmp/system.img_mount rm -r /tmp/ramdisk.img_extracted Note: cd / to avoid current working directory inside /tmp/system.img_mount or /tmp/ramdisk.img_extracted. step 5: exit fake root shell exit

Note: need to start emulator with -selinux permissive or -selinux disabled for armeabi and armeabi-v7a apps to not crash at startup.

Note: -selinux disabled is same as -selinux permissive if you see SELinux 'disabled' is no longer supported starting with API level 23, switching to 'permissive' in terminal when starting emulator.

Note: it's possible to use houdini without -selinux permissive by setting extended attribute (attr -Ss selinux -V 'u:object_r:system_file:s0' $FILE_HERE) on all houdini files but extended attributes don't work in fuse2fs.
