How to root android emulator (Android 7.1.1/ Nougat) 如何root安卓模拟器


I’m pleased to inform the community of an easier way to root android emulator (run from standalone Android SDK)


Note: SuperSU is now deprecated, but this method still works to root the emulator, and more updates will be given for newer rooting methods.


  1. Install the SuperSu.apk

    • Install the SuperSu app firstly, just do drag and drop (if running latest emulator version or sideload through adb i.e adb –e install supersu.apk)    //最简单的就是把apk文件直接拖拽进去安装

    • After installing it, when you run it shows a screen as shown below indicating “There is no SU binary installed..”. This error just confirms the device is not yet rooted.


  1. Make emulator’ system partition writable

    • As it suggests, we need to give the emulator permission to write system files.

    • Type the following code to accomplish this: emulator.exe –avd {emulator_name} –writable-system

Note: Navigate to the tools folder where Android SDK is installed and open command prompt there by pressing shift and right clicking.    //进入到Android SDK的tools文件夹,空白地方shift+右击即可打开cmd窗口

  1. Pushing su binary in system directory

    • Extract the Recovery (containing the su binaries of different architectures)

Important! Only use the su binary that matches your avd architecture e.g x86, arm etc.., and note the path where you extracted these binaries.

  • Make sure you are running adb as root and also you need to remount. Just enter these codes
  • //做到这步的时候,发现adb root后仍然不能remount,不知道有没有大佬遇到这个问题。。。。
  • 已经解决了,模拟器安装image的时候不能选择google play的要选择google Api的才可以

adb root

adb remount

Now its time to push the su binary:

This is the code I successfully usedadb -e push C:\%USERPROFILE%\Desktop\rootemu\x86\su.pie /system/bin/su

(nevermind about my specific location of su binary, any location is okay as long there is no white space)

If this fails try this pushing to this directory instead /system/xbin/su. Also for emulators running android 5.1 and below use the su and not su.pie

  1. Change permissions of the su binary

    • Next let’s do a bit of modification of the permissions of su binary. We have to do this in emulator device through adb:

    adb –e shell su root cd /system/bin chmod 06755 su

Important!! Take note of su binary path (mine is /system/bin)

  1. Setting the install directive on su binary and set a daemon

Type the codes:

su --install

and for setting up daemon:

su --daemon&

Important!! Take note of spacing

  1. Setting SELinux to Permissive(i.e turning off SE Linux)

    • Finally turn off selinux through this code:

setenforce 0

That’s pretty much it!! Open SuperSU app and it may ask to update binaries, you can use Normal method.

Open any app requiring SU permissions just to double check and indeed SuperSU ask if you wish to grant it su permissions.



Most content in reference was for older android versions and hence the reason for different commands and paths which I modified.

Special gratitude to Irvin H, whose tutorial inspired me to create this guide after myself having failed countless times, and also after seeing the need for many users to root their emulators too. I hope this will also benefit a lot

Irvin H: Rooting the android emulator –on Android Studio 2.3((Android 4.4)


As commented by SaAtomic,

This approach is still viable with Android Studio 3.0.1

After upgrading to emulator version 27.2.9 and above it now makes preserving root much easier through snapshot feature (if copying the system.img method isn’t working):

Ideally it is more like hibernating the virtual device with config intact, hence everything is preserved.


You can now save multiple AVD snapshots for a given device configuration and choose which of the saved snapshots to load when you start the emulator. Starting a virtual device by loading a snapshot is much like waking a physical from a sleep state, as opposed to booting it from a powered-off state.

This implies the only requirement to start the emulator is adding the -writable-systemparameter to the normal emulator -avd [avdname] command to start the emulator. (Running the emulator just with emulator -avd [avdname] doesn’t launch the rooted version/copy or may lead to some error)

Tested on API level 22
