recently installed android studio on my pc, created virtual device but when I click » run ‘app’ » the only thing that happens is error «Error while waiting for device: Could not start AVD», this error is in «Run» tool window, besides that there’s absolutely no information what and why that happens.
Few things worth mentioning:
I have enabled virtualization in bios
I tried deleting virtual device and create new one, no change
I have installed android sdk
Anyone knows how to resolve that problem?

Check AVD Manager if there is no permission denied for /dev/kvm. If it is the issue, open the terminal in Android Studio and run sudo chmod 777 /dev/kvm and it will solve your problem.
Better solution is change the ownership of /dev/kvm from root to the owner of current app by running the command sudo chown -R "your account name" /dev/kvm.

As of Android Studio Arctic Fox patch 4, I resolved the issue by adding a new virtual device (for the simulator) which was for ARM architecture.
Here are details with screenshots about the steps on ConfessionsOfAnAgileCoach.

Try this one. it might help.
AVD Manager
- your current running device’s option
- Show On Disk // it will open some folders and files.
- Delete all .lock folders.
- Then run.
This worked for me.

open your AVD folder from here
Screenshort of the folder option (click) to seeand Delete the ‘hardware-qemu.ini.lock’ folder and ‘your_Project_name.lock’ file and close the Android studio,
then re-launch the studio.
It will work.

I am newbie to Android and Gradle. I have checked out source code from https://github.com/nostra13/Android-Universal-Image-Loader. Also I have installed all latest versions of Android studio and gradle just today. Since the gradle version requires build tools version as 26.0.2 I have commented the line
//buildToolsVersion "23.0.2"
so that it takes now version 26.0.2 and earlier encountered error- «Failed to find Build Tools revision 26.0.2» is gone.
I created AVD in android studio and tried running sample app from above github repository and it’s suggesting to Enable VT-x BIOS. I do not know why VT-x BIOS is required or why Intel HAXM is required. I do not know whether enabling VT-x BIOS or installing HAXM would harm my computer. Hence I did not enable VT-x BIOS and not installed HAXM yet.
Can anyone guide me to get rid of below error where no other meaningful trace is shown on gradle console as you can see in the attachment.
Error while waiting for device: Could not start AVD
Attached both screenshots displaying the AVD and the error. Is there any way without enabling the VT-x BIOS or Intel HAXM. Can this step be skipped and will I be able to run this sample app? I want to keep this as the last alternative of enabling BIOS or HAXM. Has anyone tried running this sample app?

When starting the simulator, you need to download Andriod 10.0 (Google), I use Over the Wall to download and then select «COULD NOT START AVD» after downloading the downloaded mobile phone type, or when used in the second boot When you drop down to the AVD Manager, you will pop up TIPS: COULD NOT Start AVD when running the downloaded virtual phone, as shown below: 
Solution
Workaround — Open the terminal execution command:
sudo chown ly -R /dev/kvm
The role of this sentence is: , ly is my username, in exchange for your personal username.
Run the Activity under Android Studio again to display it.
Эмулятор в Android Studio не запускается
Я думаю, что это проблема со ссылкой на SDK в структуре проекта, но когда я нажимаю «Выполнить» и выбираю «Запуск эмулятора», ничего не появляется.
У меня такая же проблема. Я только что создал AVD с 768 МБ ОЗУ, и он отлично работал!
У меня была аналогичная проблема . Android-эмулятор не открывается. Вам нужно выяснить причину этого . Вы можете запустить свой эмулятор из командной строки. Для этого вы можете скопировать и вставить свою командную строку из консоли Android Studio «Выполнить» или «AVD». Например:
» android-sdk tools emulator.exe -avd Default_Nexus_5 -netspeed full -netdelay none»
Когда вы запускаете его из терминала командной строки, он выдает сообщение с ошибкой. В моем случае это было полезно для обнаружения проблемы:
.. android-sdk tools> emulator: ОШИБКА: для эмуляции x86 в настоящее время требуется аппаратное ускорение! Убедитесь, что Intel HAXM правильно установлен и может использоваться. Состояние ускорения процессора: модуль ядра HAX не установлен!
Мне нужно было активировать ускорение графического процессора с помощью инструмента, чтобы включить его на моей машине. Я решил установить из SDK Manager инструмент HAXM .
У меня была другая проблема . Например, я назначил неправильный URL-адрес для пути к скину моего виртуального устройства . Чтобы решить эту проблему, я настроил свое виртуальное устройство с допустимым скином из моей платформы sdk: ‘ android- sdk platform android- skins ‘
Сейчас открывается нормально.
Обновление 08.08.2019:
Для более новой версии Android SDK путь к эмулятору должен быть:
» android-sdk emulator emulator.exe»
В моем случае андроид зависает при запуске. Я решил стереть пользовательские данные и принудительно выполнить холодную загрузку с помощью Android Virtual Device Manager (Инструменты-> AVD Manager)
Похоже, что «Ожидание подключения целевого устройства . » — это общее сообщение, которое появляется всегда, когда эмулятор не может запуститься должным образом. И в чем причина этого? Как видите, причин могло быть много.
Я думаю, что лучший способ найти конкретную ошибку в эмуляторе — запустить его в терминале. Так:
1 — Откройте терминал и перейдите в эту папку:
2 — Запустите эмулятор с помощью этой команды:
Вы можете увидеть имя ваших (ранее созданных с помощью AVD Manager) эмуляторов с помощью этой команды:
Если все в порядке, программа не запускается, а пишет в терминале конкретную ошибку.
В моем случае приложение сообщает, что возникла проблема с загрузкой графического драйвера (« ошибка libGL: невозможно загрузить драйвер: r600_dri.so »). Как объясняется здесь , похоже, что Google упаковал с Android Studio старую версию одной библиотеки, и эмулятор не работает, когда пытается использовать мою графическую карту.
Решение? Очень просто: использовать системные библиотеки вместо упакованных в Android Studio. Как? Добавление «-use-system-libs» в конец команды. Так:
Окончательное решение — установить для переменной среды ANDROID_EMULATOR_USE_SYSTEM_LIBS значение 1 для вашего пользователя / системы. С этим изменением, когда я запускаю эмулятор в Android Studio, он также загружает системные библиотеки.
PS 1 — Самый простой способ установить переменную среды, который я нашел, — это изменить скрипт, запускающий Android Studio ( studio.sh , в моем случае он находится внутри / opt / android-stuido / bin ), и добавить в начале это:
PS 2 — Я работаю с Debian Jessie и Android Studio 2.2.3. Моя графическая карта — ATI Radeon HD 6850 от Sapphire.
ОБНОВЛЕНИЕ Декабрь 2017: у меня была такая же проблема с Debian Stretch и Android Studio 3.0.1 (та же графическая карта). У меня работает то же решение.
AVD doesn’t work after installing Android Studio [closed]
Questions on Android Enthusiasts should be asked from a end-user point of view and within the scope defined in the help center.
Closed 6 months ago .
I installed Android Studio, but when I try to run, the emulator is not working. When I googled, I find some instructions in which the
- Open SDK Manager and Download Intel x86 Emulator Accelerator (HAXM installer) if you haven’t.
-
Now go to your SDK directory (C:usersusernameAppDataLocalAndroidsdk, generally). In this directory Go to extra > intel > Hardware_Accelerated_Execution_Manager and run the file named «intelhaxm-android.exe».
In case you get an error like «Intel virtualization technology (vt,vt-x) is not enabled». Go to your BIOS settings and enable Hardware Virtualization.
- Restart Android Studio and then try to start the AVD again.
but I don’t know where is BIOS setting of my computer. I have HP desktop CPU and try to find the BIOS from start, F10 as well as from change PC setting in Windows, but all in vain.

I faced a similar problem recently on my windows 10 laptop and found out that the Intel virtualization technology (vt-x) was disabled from BIOS.
In case you are using a new laptop which comes per-installed with Windows 8/8.1/10 then chances are that you cannot enter the BIOS manually while booting. Reason being they have changed BIOS to UEFI which is no longer accessible through boot but instead you need to do the following steps:
Go to Windows > Settings > Update and Security > Recovery. Then under Advanced startup, click Restart now. The system will restart and show the Windows 10 boot menu. Select Troubleshoot > Advanced options > UEFI Firmware Settings. Click Restart to restart the system and enter UEFI (BIOS). from here you can access the UEFI menu (which is similar to BIOS)
Search for the VT-x setting (It may be named as Intel VT or Vanderpool or Virtualization Extensions or something similar depending on your OEM and BIOS.)
Intel Virtualization Technology (VT). Formerly known as Vanderpool, this technology enables a CPU to act as if you have several independent computers, in order to enable several operating systems to run at the same time on the same machine. In this tutorial we will explain everything you need to know about this technology. Intel’s virtualization technology is available in two versions: VT-x, for x86 processors; and VT-i, for Itanium (i.e., IA-64) processors.
If you want to read more please take a look at this answer.
https://superuser.com/questions/939340/what-is-vt-x-why-it-is-not-enabled-in-few-machine-by-default
And if you want to enable it then refer to this
Enable VT-x in your BIOS security settings (refer to documentation for your computer)
And if you don’t want to activate VTx go to this link and install genymotion. Also I believe you will need to install virutal machine too to run these emulators
GenyMotion

You need to enable VT-x it will not harm your computer :). And if you don’t want to do it you can use GenyMotion emulators or real devices.
-
Could not upload the screen-shot of error in gradle console because image size is bigger. But I have that checked no meaningful trace is shown over there.
-
have you enabled it through your bios ?.
-
@Umair-what is VT-x? Does this depend on what an app needs to do or is this a general thing for all android apps? Can you share link to install GenyMotion?
-
Check my answer. You will get the idea
-
-
do I need to download genymotion with virtual box or without virtual box?
-
@Prakash if you already have a virtual box then no, otherwise yes
-
@Prakash basically virtual box is VM on which your emulator will run.
-
I have installed genymotion with virtual box. Can you tell me how to create android virtual device using genymotion?
-
The video u shared is for plugin into eclipse and not for Android studio. Also I m confused of what document to follow for installation. I am trying to follow Plugin-for-Android-Studio and using JetBrains repository method. Stuck here. Don’t know what to do next?
-
@Prakash sorry i didn’t noticed that. It’s easy to add a plugin to android studio. Follow these links and you will be able to run it I am sure. Or just tell me where you are stucked at, ? tleyden.github.io/blog/2013/11/22/… genymotion.com/plugins
-
I wanted to upload screenshot but don’t know how to upload in comments
-
Will you be available to chat again? I am stuck at that point.
-
@Prakash I don’t know where you are stuck at. everything is quite clear and easy to understand.
-
to start virtual device of genymotion, does this require a license? I have downloaded trial version which said to be free for 30 days
-
@Prakash You do not need a license to run Genymotion for personal use. Paid license is only required for commercial use (earning money with the help of Genymotion). I believe you have selected the wrong option while creating your account on genyMotion.
-
what company and usage type I should select for person use?
-
@Prakash for company = «Gamer/Personal» and for usageType = «training» or «development»
-
thanks Umair. Hopefully this should solve my purpose.
-
@Prakash if my answer helped you please accept and upvote it and if you are still having some problem feel free to tell me
-
I have already upvoted. Let me check by creating new virtual device with genymotion. I will not forget to accept the answer.
-
I have accepted the answer as I am able to configure genymotion in android studio. But after this I am facing some problems related to build. I don’t know whether it will be appropriate to add the description of error here in comment. i.e. Posting that as separate question. Could you help me with that also if you are ok?
-
@Prakash you need to post a different question for that because that problem has nothing to do with genymotion. And I am glad that i could be of help. Happy Coding
