I'm trying to use emulator.exe as android emulator for Charles Proxy. But I have problem, when I launch
emulator #5.1_WVGA_API_28
I get this error:
PANIC: Missing emulator engine program for 'x86' CPU.
But I can run the emulator from android studio and it's working fine! I have an intel processor.
If you want to run emulator from command line,
<your-full-path>/emulator -avd 5.1_WVGA_API_28
For newer version of Android SDK, the emulator path should be something as below:
/<xxx>/Android/sdk/emulator/emulator
For older version of Android SDK, the emulator path is as below:
/<xxx>/Android/sdk/tools/emulator
Try either one of above to see which is your case.
Here is the official document for Android emulator command line usage: https://developer.android.com/studio/run/emulator-commandline
That was not a path/location problem on my PC.
I have to use x86_64 system images to get the emulator working from the command line...

I have solved the problem. You must install HAX drivers. You can do it here: https://software.intel.com/en-us/articles/intel-hardware-accelerated-execution-manager-intel-haxm Or just do update of SDK:
C:\Users\%username%\AppData\Local\Android\Sdk\tools\android.bat update sdk
#shizen answer worked for me using "...emulator/emulator" but even after changing the path in .zprofile (I use zsh on Mac), it was finding the old emulator. To find out which emulator your system is using, use "which emulator". In my case it was still loading the old one so I deleted the old path (rm -R /usr/local/bin/emulator) and now the correct (new) emulator loads.
I am new to Android Studio and I am having problems while using the emulator. When I try to run it keeps crashing saying:
"Cannot launch AVD in emulator" [6816]:ERROR:./android/qt/qt_setup.cpp:28:Qt library not found at
C:\Users\Jay\AppData\Local\Android\Sdk\emulator\lib64\qt\lib
Could not launch 'C:\Users\Jay\AppData\Local\Android\Sdk\emulator/qemu/windows-x86_64/qemu-system-i386.exe':
No such file or directory
I have enabled VT-x from BIOS settings yet I am having the problem. I have searched a lot and cannot find an answer. Any help will be much appreciated. Can anyone give me a solution?
Screenshot of error
This seems to be an issue relating to the recent update. A temporary solution is to launch emulator from within the /path/to/android-sdk/tools directory in the commandline.
See https://code.google.com/p/android/issues/detail?id=235461 to follow the issue.
All other answers did not work for me as "Android Emulator" was not installed with a standard installation of Android Studio. Make sure you have installed it and then try other answers if required.
For Linux or Mac systems you can add the following to ~/.profile (or ~/.bashrc):
function emulator { cd "$(dirname "$(which emulator)")" && ./emulator "$#"; }
then run to load the changes:
source ~/.profile
(or source ~/.bashrc of course)
This will allow to execute emulator until they fix the issue
(based on #10 yanokwa comment from https://code.google.com/p/android/issues/detail?id=235461)
I've installed the latest Android Emulator 26.1.2 which has solved this problem.
Btw if in your PATH you have both of this:
C:\AndroidSDK\tools
C:\AndroidSDK\emulator
The emulator command will try to use the emulator.exe inside the tools folder, which is not working.
To solve this in your PATH you need to move C:\AndroidSDK\emulator
in the line before the tools directory, in this way the emulator
executable will be searched inside the emulator folder first and will
take precedence over the one present in the tools folder
MacOS:
If you have a Mac you can move
~/Library/Android/sdk/emulator before
~/Library/Android/sdk/tools
a simple solution is to add this alias to your .bashrc .profile or equivalent
alias emu="$ANDROID_HOME/tools/emulator"
then source .bashrc or .profile or just simply open a new terminal
finally running your emulator will be as simple as emu -avd name
Zsh users can add:
function emulator { ( cd "$(dirname "$(whence -p emulator)")" && ./emulator "$#"; ) }
to .zshrc (or .zshenv).
Load changes to current shell by sourcing changed file:
source ~/.zshrc
Now you can use emulator command in zsh.
Thanks to J. Costa for his answer for bash.
I had same problem with latest Android Studio installed just yesterday on Macbook.
Though the emulator binary was available in the sdk/tools folder, Android Emulator package wasn't installed. Selecting Android Emulator in Android Studio->Preferences->System Settings->Android SDK, downloaded the emulator package and installed it.
After the emulator installation, I am able to launch the emulator.
First of all, the issue thread on Google Issue Tracker was already resolved. You don't have to set environment variable like LD_LIBRARY_PATH as a workaround any more. But you have to upgrade your Android SDK and use the LATEST emulator package (binaries). Without having that, you'll still see the annoying QT errors.
Then, it's crucial to make sure that the required SDK packages are installed to launch an emulator. When installing a specific emulator image by sdkmanager, it won't check or ask you to install required dependencies. Whenever you see error complains about ANDROID_SDK_ROOT, such as PANIC: Cannot find AVD system path. Please define ANDROID_SDK_ROOT or PANIC: Broken AVD system path. Check your ANDROID_SDK_ROOT value, it's exactly because of that.
So the 3 other essential dependencies apart from the emulator image are:
platform-tools
platforms;android-<api_level>
emulator
Which you can install via:
sdkmanager "platform-tools" "platforms;android-<api_level>" "emulator"
The api_level is the same API level your emulator image is.
For those who are still experiencing the issue even when performing the command from .../Sdk/tools directory, try adding the -use-system-libs argument.
So it should be in the following format:
path/to/Sdk/emulator -use-system-libs -avd [AVD-NAME]
For me, here is an example:
/home/cillian/Android/Sdk/emulator -use-system-libs -avd Nexus5
I had the same problem and I solved it by installing the emulator cause somehow the updates seem to have deleted it. Do that from Android Studio tools-> SDK manager. Hope this helps
I see that you should only add below into the path to be able to launch emulator
C:\Users\Ram\AppData\Local\Android\Sdk\platform-tools
C:\Users\Ram\AppData\Local\Android\Sdk\emulator.
After installing Android Studio 3.0 and higher, I see that C:\Users\Ram\AppData\Local\Android\Sdk\emulator has same files as C:\Users\Ram\AppData\Local\Android\Sdk\tools
The tools folder is missing some files, so remove the tools folder from path.
You can use below emulator commands to launch emulator from command prompt:
emulator -list-avds
emulator #Pixel_2_XL_API_26 - Based on the avd that you have setup
I have installed Android Studio 2.3.3 (today 2017-08-01) on windows 10 x64
Same issue.
I have manually installed emulator from Android Studio -> Tools -> Android -> Sdk Manager -> SDK Tools -> Android Emulator (version 26.1.2)
After installation ... same issue
I have added my path from emulator folder to my environments variables before tools path (like as one answer above) but still same issue.
Then I have deleted emulator.exe and emulator-check.exe from tools folder and this solved for mi the issue
Follow these steps to resolve that problem (Windows 10):
Check in Android studio if you installed Android emulator, if not, install it.
Check in Android studio if you installed Intel x86 Emulator Accelerator (HAXM installer), if not, install it.
In Environment variables => System variables edit "Path". You need to add this line for emulator: %ANDROID_HOME%\emulator before %ANDROID_HOME%\tools and %ANDROID_HOME%\platform-tools (The third step was a solution for me.)
For Mac
If have create emulators, try this shell code:
#!/bin/bash
cd /Users/***/Library/Android/sdk/tools/
avds=`emulator -list-avds`
echo "show All emulators"
i=0
for item in $avds
do
echo [$i] $item
let i+=1
done
read index
avds=($avds)
# echo ${avds[$index]}
emulator -avd ${avds[$index]}
*** is your user name
This problem seems to be fixed in Cordova version 7.0.X
If you are using Cordova version 6.5.0 you can fix it easily.
The root of the problem is in the emulator.js file located from the root of your project directory at ./platforms/android/cordova/lib/emulator.js
Simply update the following line, (for me it was line 205):
.spawn('emulator', args, { stdio: 'inherit', detached: true})
to
.spawn('emulator', args, { stdio: 'inherit', detached: true, cwd: process.env['ANDROID_HOME'] + '/tools'})
This will fix the relative path issue your are experiencing.
Also, there is a second fix needed for the Cordova version 6.5.0 on line 56. Simply drop the letter "s" from the word "avds" plural, to make it "avd" singular.
I was facing this issue
java.io.IOException: Cannot download
'https://dl.google.com/android/repository/emulator-windows-4266726.zip'
I updated to studio 3.0 in windows 10, my emulators stopped working.Things I did for fixing,
Deleted previous installation folders of android studio like 2.0 and 2.1 present under my username alongside .AndroidStudio3.0 folder(leaving it untouched).
Deleted previously installed emulators which any way stopped working.
Downloaded the emulator zip file manually from the link above.
Pasted its contents in emulator folder of
C:\Users\myusername\AppData\Local\Android\Sdk\emulator
Created a new emulator and started it, Bingo! it is working!!
My android studio is in the windows operating system. but most of the answers in this page do not work for me.
but I figure it out with an easy way.
In your android studio IDE, open the [Sdk manager], check if you have downloaded the [Android Emulator] and [Android SDK tool]
How to check them?
[SDK Manager] -> [Appearance & behavior] -> [System Setting] -> [Android Sdk] -> There are tabs here and choose the second one [SDK tools]. then check [Android Emulator] and [Android SDK tool].
Hope that it can help you.
Good luck!
I just solved this issue for headless emulator scenario So If I checked my andrdoid_sdk folder there are 2 executable emulator. The issue is sitting one the version
${ANDROID_HOME}/emulator/emulator
version 29.3.4
no issue
and the second one is
${ANDROID_HOME}/tools/emulator
version 26.0.3
QT issue
so make sure you're using latest emulator version especially if you need headless emulator as stated on : https://androidstudio.googleblog.com/2019/02/emulator-2818-canary.html
cd $ANDROID_HOME/tools then emulator --avd #whatever_name_it_is
It seems I was having same problems with emulator in tools folder and AS 4.1.1. A quick solution that I've found for Mac users to work with the new emulator of the emulator folder is to specify the whole path to it:
~/Library/Android/sdk/emulator/emulator <device> <flags>
I was trying on Mac and facing the similar challenge. Mistakes I was doing, is adding PATH before to ANDROID_HOME which should be come at the end. Below is my zshrc file which worked.
export JAVA_HOME=/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home
export ANDROID_HOME="/Users/rohitmandiwal/Library/Android/sdk"
export PATH=$ANDROID_HOME/emulator:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/tools/bin:$PATH
Installing Android emulator will solve the issue as this setting is not by default enabled in android studio. In android studio 3+ onwards you cannot find it under Tools-->Android-->Sdk Manager -> SDK Tools -> Android Emulator but it's under File-->Settings-->Appearance &Behavior-->System Settings-->Android SDK-->SDK Tools-->Android Emulator
I manage to solve this error. In my system varible i need to set ANDROID_HOME
For my User variable i need
both these path
C:\Users\tonyhudson\AppData\Local\Android\Sdk\platform-tools
C:\Users\tonyhudson\AppData\Local\Android\Sdk\emulator
Remember to delete C:\Users\tonyhudson\AppData\Local\Android\Sdk\tools because it will cause the error
When you have installed only Android SDK and not Android studio. You need to find out the path of the emulator and execute with full path. For example,
/usr/local/share/android-sdk/tools/emulator #test
This should resolve your problem. At least this is what worked for me.
I added the following to my ~/.zshrc file and it worked. (M1 Pro Macbook)
export ANDROID_HOME=/Users/$USER/Library/Android/sdk
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/Contents/Home
export PATH=$ANDROID_HOME/emulator:$PATH
Remember to do source ~/.zshrc after editing it.
My problem turned out to be that I was running VirtualBox at the same time as the emulator. For anybody else running into this problem, have a look here: Android emulator and virtualbox cannot run at same time. Hopefully one of the answers will give you a working solution.
You can also just open the Tools > AVD Manager from Android Studio and start the emulator manually.
There can be the bugs / updates happened in the underlying OS. So, instead of updating in .profile, /etc/environment, or .bashrc file to point adb, emulator etc, put (copy and paste) all the emulator folder inside /usr/bin directory. This /usr/bin is by default pointed by the system. Install adb tool from the terminal. This should solve everything.
And/Or, update your all environment variables in /etc/bash.bashrc file. Note that: /etc/bash.bashrc file is what gets executed everytime you open the bash terminal.
If you're using a Docker container which is running a Ubuntu x86 image, it may not be possible to run an x86-based emulator within the Docker image. You will either get the "Qt library not found" error or the "Please ensure KVM is properly installed and usable" error (more info here).
An alternative is to use an ARM-based emulator, which are easier to run, although they are slower:
# Download an ARM emulator image
android-sdk/tools/bin/sdkmanager "system-images;android-24;default;armeabi-v7a"
# Create an ARM-based emulator AVD with 250 MB SD card
avdmanager create avd -n Android_7.0_API_24 -k "system-images;android-24;default;armeabi-v7a" -c 250M --force
# Check the image is properly created and available to run
android-sdk/emulator/emulator -list-avds
# Run the emulator
android-sdk/emulator/emulator -avd Android_7.0_API_24
More info: https://medium.com/#AndreSand/android-emulator-on-docker-container-f20c49b129ef
A solution that worked for me that I've not seen here before is to link android-sdk/emulator/emulator to android-sdk/tools/emulator.
Dumb? Genius? worksforme.
I am trying to run a emulator from the Android source by loading the goldfish kernel with some of my configuration changes. Though I found a lot of questions on this, but could not find my answer.
1. I downloaded the android source.
2. I also successfully built my goldfish kernel. Now I can see the zImage in the /goldfish/arch/arm/boot folder.
After this I tried running this emulator by referring to a lot of similar questions.
Building Android from source - emulator and AVDs, Running emulator after building Android from source, How to compile android goldfish 3.4 kernel and run on emulator. But unfortunately didn't solve my problem. When I try to run the emulator with :
./emulator -debug init -kernel Thepath/goldfish/arch/arm/boot/zImage -avd firstAvd -wipe-data
I get an error that AVD is not found. I then found this blog, https://yaapb.wordpress.com/2012/09/22/build-a-custom-android-emulator-image/ where it says to first make the emulator from the source tree by the following commands:
$ source build/envsetup.sh
$ lunch full-eng
$ make -j4
$ emulator -wipe-data &
Then to run the emulator with my modified kernel, I need to run :
$ cd ${ANDROID_BUILD_TOP}
$ emulator -kernel ~/workspace/android/goldfish/arch/arm/boot/zImage -wipe-data &
Though I am trying to do this, the process of creating the emulator with the make command is taking hours. 7% in 90 mins till now. So in the mean time I wanted to know if anyone can tell me that to run an emulator with my kernel, do I need to first create an emulator from the source? Also, I dont find the system.img, ramdisk.img files in the android source tree. Is it normal or I ge them when I create an emulator?
**
EDIT
**
I would also like to know if I can run the emulator without the make -j4. The Android source tree also includes the SDK. Can I run the Emulator from the SDK. If yes, how? The google official docs say to run the following command form the /tools folder in the sdk. But there is no tools folder in the sdk folder.
After you have built the sources, you should not run build process once again in order to use the emulator. Simply go to the folder with your AOSP code and run the following commands:
$ cd ${ANDROID_BUILD_TOP}
$ source build/envsetup.sh
$ emulator -kernel ~/workspace/android/goldfish/arch/arm/boot/zImage -wipe-data &
The command source build/envsetup.sh will add additional commands to your shell, and you should be able to run emulator without building it one more time from scratch.
With 25rc1 of the SDK tools I am having a problem when starting the emulators from $PATH
➜ ~ which emulator
/home/ligi/bin/android-sdk/tools/emulator
➜ ~ emulator #M
Could not launch './qemu/linux-x86_64/qemu-system-i386': No such file or directory
➜ ~ /home/ligi/bin/android-sdk/tools/emulator #M
console on port 5554, ADB on port 5555
Anyone knows a workaround? I could write a script to start emulators and cd in tools before but perhaps there is a better solution.
I encounter this one in android studio 2.3 which use new path for the emulator so try the following:
do not use emulator executable in the: sdk-path/tools/ directory but instead use the one found in the : sdk-path/emulator/
and also remove or rename the emulator found in the sdk-path/tools directory.
and because android sdk shipped with it's own libstdc++.so.6 you need to do the following to avoid the libGL error:
cd $ANDROID_HOME/emulator/lib64/libstdc++
mv libstdc++.so.6 libstdc++.so.6.bak
ln -s /usr/lib64/libstdc++.so.6 $ANDROID_HOME/emulator/lib64/libstdc++
Try this, it work for me on Windows.
Tools -> Android -> SDK Manager -> SDK Tools -> Android Emulator
Then click on Apply.
If you're launching the emulator from command-line, try setting the current directory to your android sdk "tools" folder first.
This works for me as a workaround:
pushd ${ANDROID_HOME}/tools
emulator -avd ${EMULATOR_NAME} -wipe-data&
popd
This one works for me on MacOS Sierra.
Preference -> Appearance & Behavior -> System Settings -> Android SDK -> SDK Tools (tab)
Tick on Android Emulator and Apply
I had the Android Emulator up to date under SDK Tools. But I was still getting the error. Adding the following line to ~/.bash_profile solved the problem for me:
PATH=$ANDROID_HOME/emulator:$PATH
In Ubuntu 19.10!
With the environment variables already configured ($ANDROID_HOME), you should be able to list the AVDs, but if you are unable to start the AVD, do the following:
# Check the AVD target name
emulator -list-avds
# But to start do:
$ANDROID_HOME/emulator/emulator #avd_name
or
/home/$USER/Android/Sdk/emulator/emulator #avd_name
Make sure that ANDROID_EMULATOR_FORCE_32BIT is not set in your environment
In Virtual device configuration, set Emulated performance to Software GLES 2.0
yah my dns is blocked in the region i am visiting so i was searching for a way to add dns servers and start emulator at command line. default emulator in path did not work. instead go to your android SDK home and you'll see a emulator in there. use that emulator executable like this:
emulator -avd Nexus_5X_API_26 -dns-server 8.8.8.8,208.67.222.222,199.85.126.10,8.8.4.4
i think you can give 4 dns's. anyway this is a side note. back to the issue:
people here did not mention much that you need the -avd flag with it. wanted to point that out.
Do not use $ANDROID_HOME/tools/emulator, it will cause error when you launch every time unless you change dir.
There is a another emulator in $ANDROID_HOME/emulator.It is a good choice
I have downloaded and compiled Android source code per instructions on Android source website (http://source.android.com/source/building.html)
I chose
$ lunch full-eng
an emulator engineering build and everything has compiled just fine.
Then it says to launch the image inside an emulator just type:
The emulator is added to your path automatically by the build process. To run the emulator, type
$ emulator
Well, not sure it is added to the path. Typing emulator does not do anything.
However if I go to
out/host/darwin-x86/bin/emulator
emulator: ERROR: You did not specify a virtual device name, and the system
directory could not be found.
If you are an Android SDK user, please use '#<name>' or '-avd <name>'
to start a given virtual device (see -help-avd for details).
So I am confused ... at this point do I have to create an AVD ?
How do I create an AVD for this image exactly ?
Has anyone done this on MAC can they supply me with some instructions ?
Thanks
I'm not sure if there is any difference on osx, but it is a common error on Linux. After you build the whole AOSP, the building process will add the <AndroidBase>/out/host/<host-arch>/bin/emulator into the PATH, but after you restart your computer or open another session, emulator will no longer be in the path.
To fix the "You did not specify a virtual device name, and the system
directory could not be found" error, you can explicitly set ANDROID_PRODUCT_OUT to point to your disk image directory. In general, the disk image directory would be <AndroidBase>/out/target/product/generic. So
$export ANDROID_PRODUCT_OUT=<ANDROID BASEDIR>/out/target/product/generic/
would help.
Actually, you can run
. build/envsetup.sh
setpaths
It will do a similar work for you.
I build with aosp_x86_64-eng and have verified that the following will launch the emulator in a new terminal window:
cd /[your AOSP WORKING_DIRECTORY]
source build/envsetup.sh
lunch aosp_x86_64-eng
cd $ANDROID_PRODUCT_OUT
emulator
