android AVD (Emulator) exit - android

I cannot open the emulator, each time I Press launch avd. the emulato exit immidately before launching.
and it seems like there is no integration ? or something wrong as I have the below error: emulator unknow.
even though I have an emulator.
I don't even know what sort of issues is this!
as it exits without any error message.
Edit:
I solved the issue by simply reinstalling Intel HAXM

When this type of problem happens, best way is to make sure you have followed below points correctly.
You have proper SDK installed
You have Intel HAXM & virtualization option enabled in your BIOS
Configure emulator correctly, download the Intel X86 Atom system image for better performance.
Disable and then Enable ADB Integration
User arm instead of x86 if you have AMD processor when creating emulator.(In most of case)

Could not start AVD, VT-X is disabled in bios

I'm trying to run an android emulator but I continuously keep running into this problem. I've already enabled VT-X in my bios but I'm still running into this error over and over again. I've read that antivirus can be a problem with it running but I'm sure that's not the case here. I've also updated everything else and I've wiped the data since I've read that it also helps, but nothing still.
When I try opening the emulator in vs code it gives me the error that the emulator did not connect within 60 seconds, so I tried opening it via android studio first and then vs code but it's giving me the avd and VT-X error.
How can I fix this?
you might need to install intel HAXM (if your processor is Intel) or Hypervisor (if your processor is AMD).
steps:
Settings -> System settings -> Android SDK
then choose SDK tools from the top
find Intel Emulator Accelerator HAXM or Android Emulator Hypervisor Driver(depending on your processor choose the right one)
check it if it's not checked, click apply then try again it should work

Error while installing Android Studio

I am trying to install android studio. I have java as the below command output shows.
java version "1.8.0_51"
However when I install it right at the end of the installation the following error appears.
Failed to install Intel HAXM. For details please check the installation log: "C:\Users\Henny\AppData\Local\Temp\nsvBCFE.tmp\haxm_silent_run.log"
Does anyone know whats wrong?
Do you know how to turn on "Intel Virtualization Technology"
Your CPU has to support it first. If it is not available, then you are out of luck. If you got Intel VT, then you shall find the option to turn it on/off in your computer BIOS.
But if you want HAXM for emulator, just go for Genymotion which is VirtualBox based and much faster than stock emulator.

How do I fix HAX carnel module issue in Android studio?

I have successfully installed Android Studio from their official homepage.
But the problem is I can't strat my emulator. Once I run the program, it shows the following error in my command window.
"C:\Users\Jabir Al Fatah\AppData\Local\Android\sdk1\tools\emulator.exe" -avd Nexus_5_API_21 -netspeed full -netdelay none
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!
Now, I have uninstalled the Studio at least 10 times and installed them again. I have searched online about all the possible solution. I have HAXM installer installed properly in my sdk.
I have enabled the virtualization in BIOS. But none of those really help.
I wanted to exucute the intelhaxm.exe file. But the problem is I don't find any sdk folder in my drive. I can see the specified derictory for sdk while installing the studio, but in reality that folder is never created and never exist in my drive.
Please help me to find a solution.
Windows 8. Android Studio.
Make sure if virtualization is enable : go through those steps provided below.
Goto setting -> change pc settings-> general->then see on right side
by scrolling the frame down-> you will see under advance start up
restart now button press it->then choose an option window will
open->choose troubleshoot->under troubleshoot choose Advance
option->then under Advance options choose UEFI Firmware option->then
press restart->press f10 for BIOS->see the menubar where you will
find system configuration menu inside it you will see the
virtualization Technology "enable" it ->now go for exit saving
changes in exit on menu bar..
C:\Users\username\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm-android.exe
(in username : please enter valid user name)
install it and restart your Android Studio.
if you make few changes on above process it is same for win 7 and also same for eclipse have fun!!
I had the same problem. You might wanna read this post:
Error in launching AVD with AMD processor
In particular, after installing HAXM through the SDK manager, which in itself didn't fix the problem, try to run the intelhaxm-android.exe. This showed that I had some hardware virtualization problems (like the error mentioned in the other post).
I'm switching to the Genymotion thingy.
Cheers, B.
Eventually, I found a different solution, as the Genymotion wasn't the right thing for me.
In the AVD manager, I changed the processor type of the AVD to ARM and this doesn't need the HAXM thing at all. This surely doesn't make stuff very fast, but it got me a working emulator. Once it's running, it's not that bad.
Hope this helps.
Cheers!

How can I run Android emulator for Intel x86 Atom without hardware acceleration on Windows 8 for API 21 and 19?

I have not enabled Hyper V or hardware acceleration and don't want to either.
Is there any way that I can start android emulator for Intel x86 Atom Without hardware acceleration on Windows 8
I have created AVDs with every combination possible and each one has failed to start the AVD emulator instance , throwing the same error when starting
emulator: ERROR: x86 emulation currently requires hardware
acceleration! Please ensure Intel HAXM is properly installed and
usable. CPU acceleration status: HAX kernel module is not installed!
OR is it that, the images given for Intel Atom 86 and 64 cannot run without HARDWARE ACCELERATION AND hyper V for API 21 and 19
I have found lots of similar question and read almost all documentation, but it is not clear if they can or cannot run without hyper v and hardware acceleration, hence this direct question
How do you test on android in such cases ?
In current AVD manager you can't. You just have the opportunity to use ARM images which will not need hardware virtualization.
To run ARM images:
Open AVD manager.
Create a new 'Virtual Device' OR right click an existing image and select 'Duplicate'
Choose arm* instead of x86/x64.
Continue with the wizard.
Run!
Although this is the available solution but still a slow one !!
You can still force the use of the soft x86 emulator by running it from the command line and using the -no-accel option, i.e.
from the SDK/tools directory:
emulator -avd AVD_NAME -memory 768 -no-accel -gpu on
BUT this still won't work with the current (V24) SDK, because the current x86 system images crash the soft x86 emulator :-(
The only way I got this working again was to downgrade the SDK tools to V22.3 from here:
http://dl-ssl.google.com/android/repository/tools_r22.3-windows.zip and to buld an AVD using a downgraded system image, for instance https://dl-ssl.google.com/android/repository/sys-img/android/sysimg_x86-17_r02.zip. (So this is no help if you need to test on more recent versions of Android).
Google have moved on to an updated version of their emulator based on a more recent version of qemu, and provide binaries for arm and mips emulators, but have omitted to ship the x86 equivalent (there is no emulator-ranchu-x86.exe and emulator64-ranchu-x86.exe). If they did so, or if someone else went to the trouble of setting up and compiling their emulator source with the "x86" flag on, then _x86 soft emulation could conceivably be made to work again.
Short Answer: No. Until recently(about 1 month ago), you could do that but with the latest updates, it is not possible. (see Update to Android SDK Tools 23.0.5 and avd doesn't start).
I was doing something similar: Doing development in a virtual machine and hence couldn't use the Hardware acceleration features as they are available only in the host machine. I was using Intel x86 images with Use Host GPU option; as they were much faster than the ARM version even without hardware acceleration. But then, after this update, my emulator AVDs which were working earlier are no longer starting with the same exact error message. Also, both genymotion and Xamarin Android emulators can't be used as they also need hardware acceleration(they are actually VMs which use Hardware acceleration for speed, and hence can't be run inside another VM).
I have found this solution but haven't tried it yet. The basic idea is that to still develop inside a VM; but for testing connect to an Emulator running on the host machine(and this Emulator VM can now use the hardware acceleration feature).
Same issue as in Error in launching AVD:
1) Install the Intel x86 Emulator Accelerator (HAXM installer) from the Android SDK Manager;
2) Run (for Windows):
{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe
or (for OSX):
{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\IntelHAXM_1.1.1_for_10_9_and_above.dmg
3) Start the emulator.
The usage of the Hardware acceleration depends on the System Image you choose on the emulator.
So,
Go to AVD manager, create virtual device, select hardware, click next.
Choose the System Image that does not require HAXM (hardware
acceleration) for running. (That is appears at the right bottom of
System image window.)
Note: for other systems that require HAXM, there no way to run them without hardware acceleration.
use bluestacks as a emulator for best performance. blusestack working fast without hardware based emulation
To connect bluestack to android studio.
Close Android Studio.
Go to adb.exe location.(Bydefault its C:\Users\Tarun\AppData\Local\Android\sdk\platform-tools)
Run adb connect localhost:5555 from this location.
Start Android Studio and you will get Blue Stack as emulator when you run your app.
Is there any way that I can start android emulator for intel x86 atom Without hardware acceleration on windows 8
Not with the standard Android SDK emulator, as it requires Intel's HAXM, and HAXM wants virtualization extensions to be enabled.
Whether Genymotion or something else from another independent developer can support your desired combination, I cannot say.
refer intel.com's requirements : Important: Intel HAXM cannot be used on systems without an Intel processor, or with an Intel processor that lacks the hardware features described in the "Hardware Requirements" section above.To determine the capabilities of your Intel processor
[Installation Instructions for Intel® Hardware Accelerated Execution Manager ] https://software.intel.com/en-us/android/articles/installation-instructions-for-intel-hardware-accelerated-execution-manager-mac-os-x
My PC does not support vt-x, I can not use android studio 1.0.2.
yes is possible to run your android emulator without have a hardware accelerator.
In fact to do that, you need to open your android virtual device.
When you reached to system image configure, it suggest you which version of android image you want to use.
Whatever version of android system image that you select,you need to make sure that,ABI is armeabi-v7a and, you target is System image ameabi-v7a with google APIs.
And then complete the rest of task and check out your emulator.
You need "VT-x supported processor" at least to run Android emulator with Hardware acceleration.
If you have enabled or installed "Hyper-V" in your windows 8 then please remove it and disable the "Hyper threading" and enable "Virtualization".
I've run into the same problem, I found the solution at http://developer.android.com/tools/devices/emulator.html#vm-windows
Just follow this simple steps:
Start the Android SDK Manager, select Extras and then select Intel Hardware Accelerated Execution Manager.
After the download completes, run [sdk]/extras/intel/Hardware_Accelerated_Execution_Manager/IntelHAXM.exe
Follow the on-screen instructions to complete installation.
I have a pc with intel c2d without hardware accelaration i am having same problem in android studio. firstly i get bored with android studio and installed eclipse+sdk+adt then i have installed every thing and started emulator it worked then the same emulator worked in android studio for direct launching application in android studio and i have also runned the sample app that emulator so you can run android studio without virtualization technique even your processor does not sopport vt-x
When Run 'app' (green triangle):
In Device Chooser select Launch emulator and click the button [...]
Rigth click on Nexus (or other) click on Duplicate
In the O.S. (Android 6.0 example) click change:
Clic on Show downloadable system images.
Look for armeabi-v7a O.S. and click download.
Set this O.S. in the device.
Finish, and choose this Device for the emulation.

Emulator in Android Studio doesn't start

I think it's a problem with the SDK reference in Project Structure, but when I click run and I choose Launch Emulator nothing appears.
I had the same problem. I just created the AVD with 768 MB RAM and it did run fine!
UPDATE: November 2022
This answer was almost from 10 years ago and will most propably not work on current version of Android Studio.
I had a similar problem... Android Emulator doesn't open.
You need to discover the reason of this... You could run your emulator from the command line. For this you could copy and paste your command line from "Run" or "AVD" Android Studio console.
For example:
"{path}\android-sdk\tools\emulator.exe -avd Default_Nexus_5 -netspeed
full -netdelay none"
When you launch it from a command line terminal, It give you a message with the error.
In my case it was useful for discover the problem:
..\android-sdk\tools>emulator: ERROR: x86 emulation
currently requires hardware acceleration! Please ensure Intel HAXM is
properly installed and usable. CPU acceleration status: HAX kernel
module is not installed!
I needed to activate GPU acceleration with a tool to enable it on my machine.
I solved it installing from SDK Manager the tool HAXM...
I had another problem... For example i had assigned a bad url for skin path of my virtual device...
To solve it I have configured my virtual device with a valid skin from my platform sdk: '{path}\android-sdk\platforms\android-{number}\skins{SCREEN_SIZE}'
Now it is opening fine.
Update 8/8/2019:
For newer version of Android SDK, emulator path should be:
"{path}\android-sdk\emulator\emulator.exe"
reference (thank you #CoolMind)
In my case the android hangs at start up. I solved by wiping user data and forcing a cold boot, using Android Virtual Device Manager (Tools->AVD Manager)
It seems that "Waiting for target device to come online ..." is a generic message that appears, always, when the emulator can not start properly. And what's the cause of that? As you can see, there could be many causes.
I think the best way to find the concrete error with the emulator is to start it within a terminal. So:
1 - Open a terminal and go to this folder:~/Android/Sdk/tools
2 - Start the emulator with this command:
./emulator -avd EMULATOR_NAME -netspeed full -netdelay none
You can see the name of your (previously created with AVD Manager) emulators with this command:
./emulator -list-avds
If everything is ok, the program doesn't start, and it writes in the terminal the concrete error.
In my case, the application says that there is a problem loading the graphic driver ("libGL error: unable to load driver: r600_dri.so"). As it is explained here, it seems that Google packaged with Android Studio an old version of one library, and the emulator fails when it tries to use my graphic card.
The solution? Very easy: to use the system libraries instead of the packaged in Android Studio. How? Adding "-use-system-libs" at the end of the command. So:
./emulator -avd EMULATOR_NAME -netspeed full -netdelay none -use-system-libs
The definitive solution is to set the ANDROID_EMULATOR_USE_SYSTEM_LIBS environment variable to 1 for your user/system. With this change, when I run the emulator within Android Studio, it will also load the system libraries.
PS 1 - The easiest way I found to set the environment variable, it's to modify the script that launches the Android Studio (studio.sh, in my case it is inside /opt/android-stuido/bin), and add at the beginning this:
export ANDROID_EMULATOR_USE_SYSTEM_LIBS=1
PS 2 - I work with Debian Jessie and Android Studio 2.2.3. My graphic card is an ATI Radeon HD 6850 by Sapphire.
UPDATE December 2017: I had the same problem with Debian Stretch and Android Studio 3.0.1 (same graphic card). The same solution works for me.
1) Open SDK Manager and Download Intel x86 Emulator Accelerator (HAXM installer) if you haven't.
2) Now go to your SDK directory (C:\users\username\AppData\Local\Android\sdk, 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.
3) Restart Android Studio and then try to start the AVD again.
It might take a minute or 2 to show the emulator window.
If you are new to Android studio, you need to follow few basics steps in configuring the emulator.
Make sure you have proper SDK installed
Make sure you have Intel HAXM & virtualization option enabled in your BIOS
Configure emulator correctly, download the Intel X86 Atom system image for better performance.
Go through this blog, http://www.feelzdroid.com/2015/05/android-studio-emulator-not-working-solution.html
Here they have explained clearly, what are the problems you face while running & resolution for the same.
With Ubuntu, I had the same problem. I solved it by changing file /dev/kvm permission to 777:
sudo chmod 777 /dev/kvm
you need to install "Android Emulator"
Go to
SDK Manger -> Appearance & Behavior -> System Settings -> Android SDK -> SDK Tools.
and set a hook at Android Emulator
I had the same issue in Android Studio 2.3.3 on Mac OS X 10.12.6 and the issue was caused by Android Studio using an old version of HAXM (6.0.3 when it should have been 6.2.1):
$ kextstat | grep intel
148 0 0xffffff7f8342c000 0x14000 0x14000 com.intel.kext.intelhaxm (6.0.3) 50449AFC-F7C6-38A0-B820-233E8A050FD6 <7 5 4 3 1>
Removing and reintalling HAXM from within Android Studio according to the instructions didn't work: https://software.intel.com/en-us/android/articles/installation-instructions-for-intel-hardware-accelerated-execution-manager-mac-os-x
Instead, download the HAXM installer manually or if that link expires, find it under https://software.intel.com/en-us/android/tools under Intel® Hardware Accelerated Execution Manager (Intel® HAXM).
After running the installer, it now shows that the current version of HAXM is installed:
$ kextstat | grep intel
169 0 0xffffff7f83472000 0x1d000 0x1d000 com.intel.kext.intelhaxm (6.2.1) 7B6ABC56-699C-3449-A0EC-BEB36C154E3C <7 5 4 3 1>
After upgrading HAXM manually, I'm able to launch x86_64 emulators.
Old answer, which might work instead (note that this didn't work for me for x86_64 images):
Create a new device:
Tools->Android->AVD Manager
+ Create Virtual Device
Tablet -> Nexus 7 -> Next
The Recommended tab should be highlighted.
Even though I had the API Level 25 SDK installed, it showed:
Nougat Download 25 x86 Android 7.1.1 (Google APIs)
So I clicked Download link which seems to have repaired the API Level 25 SDK. I finished creating my new device and it ran fine.
Unfortunately I had already deleted my old device, so if this works for someone else, please leave a comment here to let us know if your original device worked afterwards, thanks!
I'd like to post a link to this answer as it might help out any persons in this thread running into issues starting a virtual device with more then 768 mb of memory;
How to make an AVD with > 768MB RAM To emulate Galaxy devices
I have similar problem but I have solved it by switching to "Android 4.2.2 armeabi-v7a" (I needed to test it on Jelly Bean) in my AVD and it fixed the problem for me.
What seems to happen is that my processor is AMD and Intel X86 hardware emulation couldn't start. So I changed to use "API" other than "x86" (even though it recommended me to use x86). Hope this helps.
I spent several hours on this problem. What worked for me was opening the Tools->Android->SDK Manager, choosing Android SDK under System Settings on the left of the screen and going to the SDK tools tab. I then unchecked the settings for Android emulator and the Intel x86 Emulator Accelerator. I applied these changes, restarted Android Studio and then re-checked these option and applied the changes. The program reinstalled the emulator components and things seem to work. Hope this helps someone.
In Android Studio 2.3.3 I was able to get my AVD to start and run by changing Graphics in the Emulated Performance section from Automatic to Software-GLES 2.0:
I was able to infer this after following the advice at https://stackoverflow.com/a/44931679/1843329 and doing:
$ ./emulator -avd Nexus_4_API_21 -use-system-libs
which resulted in:
emulator: ERROR: Could not initialize OpenglES emulation, use '-gpu off' to disable it.
And when I did:
./emulator -avd Nexus_4_API_21 -use-system-libs -gpu off
the emulator then launched.
Wipe data of AVD like that picture and run your program. it's work for me.
If anyone is still having trouble with launching the avm take note of the android studio event log when you try to run the avm. When I tried running the avm android studio mentioned that my environment variable ANDROID_SDK_HOME was set to the same place as ANDROID_HOME and it shouldn't be. It recommends deleting the variable ANDROID_SDK_HOME which I did and then restarted android studio and avm started working.
Access the BIOS setting and turn on the virtualization feature. Mine was together with options like cpu fan speeds and stuffs.
Then make sure that Hyper-V is turned off in the windows features ON/OFF.
Then reinstall the intel HAXM, this should fix this issue.
edit this file:
sudo nano .android/avd/your_emulator.avd/config.ini
change lines
hw.gpu.enabled = yes
hw.gpu.mode = auto
to
hw.gpu.enabled = no
hw.gpu.mode = off
It works for me !
just check out if you have this problem "vt-x is disabled in bios"
in this case you need to enable virtualization technology bios
It probably won't start because you
no CPU is installed, then follow this answer: Unable to create Android AVD because of Target and CPU/ABI settings?
OR
don't have the correct SDK downloaded
If you migrated your project from Eclipse chances are that on running an emulator you will get stuck with this message not seeing anything else:
Waiting for device.
If you open the device manager you probably see something like this:
Just recreate your devices.
I've faced similar problem. You can edit the configuration or create new AVD with higher RAM. Also try increasing Heap to 128. Emulator will work smoothly even without HAXM
I had the same problem. I just Created New AVD with 768 MB RAM and it did run fine for me. I Used for API 22(Lollipop Version).
Besides using an external emulator such as bluestacks, you can also create a new new AVD and choose a system image with an ABI of armeabi-v7a with an API level of 21, instead of choosing ABI of x86 which fails.
I was having the same problem, i tried this and it worked. hope this will be useful as well.
Check if the following tools are installed or not in the Android SDK Manager as shown in this picture:
One reason could be that the chosen ABI does not fit to your system. For me, only arm64 is working.
I had the same problem on Windows 10, after I moved my android-SDK folder to D:/ as I was low on space on c:/.
It turned out that the Android emulator looks for Android SDK via Global (environment) Variables, not the path defined inside Android Studio.
So I edited the Environment variable of ANDROID_HOME and that was it.
If your emulator worked fine but suddenly it doesn't, just restart the machine and run again.It worked for me.
I faced the same problem. From some research that I did, I realized that my computer does not support virtualization. So I had to install BLUESTACKS.
Believe me it worked...you can also try it.
Just go to your directory C:\Android\sdk\platform-tools and double click adb
Ensure that your bluestack is running.
When you try to run the project, it automatically shows up to run with the bluestacks....just choose the bluestack and you are done.
If you want the setup of bluestack, just google it you can have a number of sites to download from for free.
I performed the procedure below, and was successful.
Execute this command down.
npx react-native info
This command return the log file the npm (example)
C:\Users\Robinho\AppData\Local\npm-cache\_logs\2020-11-22T19_35_23_842Z-debug.log
In my case was permission in dir file in windows SO.
I restarted my computer clicked F1 for the Bios setting and checked the virtualization technology box and saved the changes. The AVD worked without glitches after my computer booted. This article explains it. Hope somebody finds this helpful.
I was having this same problem. I decided to create (see the button at the lower-left). I defined the image to match my device and that seems to work.
I am thinking with Android Studio at version 1.0.1, there are still plenty of bugs.
