I seem to have messed up AVD Emulator and need some expert help in solving the problem.
Here are the symptoms:
When I try to open my_avd (my default avd) from AVD Manager, it takes a very long time to load (approx 10 - 20 mins). When loading completes, it just hangs and does not respond to any clicks (unlock mode!).
I try loading my app on this emulator, it is abandoned with:
"emulator-5554 disconnected! Cancelling 'com.app.xyz.xyzactivity activity launch'!"
When trying to launch 'my_avd' from terminal ('...android-sdk-linux/tools $ ./emulator -avd my_avd'), the load time is less, but it abandons with a "Segmentation fault" error in terminal.
I have tried deleting & re-creating my_avd multiple times, but no go.
Have tried increasing the 'Device ram size' to 1024 also, but even that did not help.
Tried the 'Snapshot: Enabled' mode while creating my_avd, but that only worsens the problem.
Have reinstalled eclipse, android sdk, etc.
I am using Eclipse, Android 4.0 (API 14) on Ubuntu 11.x (x64 processor with ia32-libs installed).
Any help/ suggestions will be highly appreciated.
Thanks in advance

Try another API version. I have this problem with API 14 and 15, but works fine with all the others. If you can't get it to work with, for example, the API 8 or 10 then you got a problem with your AVD emulator. I would suggest you to let the Eclipse choose the device for you (based on the your target version and the devices registered on your AVD Manager). Check the configurations of the device and make sure that they are the same of the real device you're emulating. Here goes the Motorola_spice_key (android 2.3.3) config:
Name : Motorola_spice_key
Device : 2.7'' QVGA(240x320:ldpi)
CPU/ABI : ARM(armeabi)
Target : Android 2.3.3 (Api level 10)
skin : 240x320
snapshot: true
Memory - RAM/VMHeap : 512 / 16
Internal Storage: 200MiB
SD Card : 512Mib
Try this one. If fails, then you might have to reinstall the emulator.

Suddenly my Android Emulator stopped working and it shows only black screen. I tried ADB devices with cmd and it says device offline. My Android Stuido version 4.0 . Intel HAXM version 7.5.6 . Android Emulator version 30.0.12 . I also tried this command in cmd --> "emulator -avd Pixel_3a_API_28 -gpu host". then it says " emulator: INFO: QtLogger.cpp:68: Critical: UpdateLayeredWindowIndirect failed for ptDst=(1429, 210), size=(300x21), dirty=(300x21 0, 0) (A device attached to the system is not functioning.) ((null):0, (null)) ". I also tried changing quick boot to cold boot in virtual device verify configuration. Tried changing android system image to lolipop, marshmallow. Tried changing avd device to pixel, nexus, generic devices and tablets. Non of them worked. Is there anyone who can give me a solution for the problem? My device has seperate VGA(GTX 1050ti). Windows version Windows 10 V2004.
The Emulator has a lot of problems since the last update. I got the same problem and I tried to solve it in many ways , and it worked suddenly and stopped working 2 days later.
Until they make it work properly I advise you use Genymotion or a regular phone.
Same problem had happened with me ....In my case the problem was about selection of wrong system image file .I had installed R (Api level 30) x86 for my emulator but it starts giving me problems so instead i installed R(Api Level 30)x86_64 for my emulator and fixed all . Make sure you install x86_64 system image file and give a try
I downloaded the Android Studio 3.0 Canary 1 preview and used the AVD manager to download the Android O x86 system image. When I set up an AVD with the wizard, using the Pixel phone as the hardware. When I start the emulator, it just hangs on the boot screen forever.
I had the same problem. Make sure to create a new virtual device instead of editing an existing one.
My OS is Debian 9. I have the same problem for API 26, but I can launch the emulator with API 25 without a problem thanks to this link: https://stackoverflow.com/a/42903352/6603006
If you have any problem with API 25 on AVD Manager, you can use Genymotion application. It's fast and stable.
I was facing a similar issue, i did the following steps to fix it
1) Updated Haxm and emulator from the SDK manager to the latest version
2) Delete the existing AVD with android 26 and create a new one
3) Tried emulating a phone with a lower resolution (like nexus 4). Pixel and pixel XL have high resolutions and run very slowly, so unless you HAVE to use the pixel device, I would recommend a lower res device which will put less strain on your machine. When I tried running API 26 on an emulated pixel it took hours to boot up.
1.Delete all existing AVDs.
2.Invalidate Caches and restart
3.Clean and rebuild project
4.Create new AVD.
And make sure you have the latest version of emulator and HAXM installed from SDk Manager.
hope this helps.
Look at bellow page. it has explained with details:
https://www.andreszsogon.com/using-android-8-and-9-emulators-without-android-studio/
briefly I did these steps to solved the problem:
Update Android SDK Emulator to a higher version
install higher System Image (for API 26)
install or update HXAM
delete old AVD machines
create new AVD machine with this configuration: ( RAM: 2048 , VM Heap: 256 )
i want to set up an android emulator, i downloaded android 4.4 (kitkat), tools, and all the extra's
the emulator is loading forever, its already loading for 2 hours, the android startup boot logo is not laggy, so the emulator is not slow.
I rebooted multiple times, and tried different devices
my emulator:
device: 10.1" WGXA (tablet) (1280 x 800: mdpi)
Target: android 4.4 - API level 19
CPU: ARM (armeabi-v7a) <--- cant change this
Memory Options: RAM:768 VM Heap: 32
Internal storage: 4096
Emulation Options: use host GPU
Computer specs:
4.2GHz 8-core cpu
4GB ram
and lot more
if i look in task manager it is using 15%cpu, 470MB RAM and 0MB disk speed
when you're using the Windows OS, you have to set the RAM to 512Mb in order to get the AVD to run properly.
Hope this helps as 2 hours is an awful long time for the emulator to load.
Had the same problem, try starting the AVD on its own and wipe user data before trying your app.
you are running these settings
10.1" WGXA (tablet) (1280 x 800: mdpi)
CPU: ARM (armeabi-v7a)
use host GPU
you must have a SUPER COMPUTER.... try a lower resulion start with 800x400,
if you have an INTEL pc,
download the "INTEL" engine from the SDK-MANAGER.API19
then use "use the GPU" setting and choose the "engine: intel" setting when creating an emulator
if you have a non-intel, then im sorry, stick with 800x400 resolution
Open android sdk manager
Extras-> install Android Support library
I had a problem on Windows 8 64-bit, with fresh installation of Eclipse and Android SDK - Virtual device was starting "forever".
I found this thread http://gotoanswer.stanford.edu/?q=android+emulator+forever+launching and link to
Can having spaces in the android sdk path cause problems in eclipse?
Solution: I moved Android SDK from
C:\Program Files (x86)\Android\android-sdk
to
c:\android-sdk
Changed location in Eclipse, and this fixed a problem for me. Now AVD launches normally. I have not found any other comments on the reason or explanation.
I hope it will help someone else.
I'm trying to run the Android emulator with the ICS (Android 4.0) OS but after a 15 minute wait on a fast quad core machine, it's still not doing anything. I understand it's emulating the arm cpu, hence it's slow - but this hasn't even gotten off the loading screen yet! Has anyone managed to get it to run? Any tips?
Try launching without the Launch from snapshot feature
Launching some of my AVD's from command line with
./emulator -avd ...
Gives
savevm: unable to load section cpu
that may or may not be related to the problem(?), but basically launching without the snapshot starts up the emulator.
This happened after I upgraded to Android SDK to 4.0
My solution is the starting Emulator manually but with Target 2.2., let's say with API level 8, then your project will be easily loaded on Emulator.
I made sure to turn off "Load from Snapshot". And mine will still not load. I am going on about an 1 hour now and still sitting
In my case, I succeeded to get ICS emulator by executing $ emulator-arm -avd your_avd_name whereas launching from eclipse (i.e. going through emulator.exe instead of emulator-arm.exe) fails consistently.
WARN/WindowManager(61): No focus window, dropping: KeyEvent{action=0 code=82 repeat=0 meta=0 scancode=229 mFlags=8}
That seams a problem of 1.6
Upgrade to 2.1 and shall disappear.
I was faced with a blank black screen after the emulator was started by Titanium and none of the emulator buttons such as Menu or Home did anything.
To fix it I entered the following commands from the sdk / tools directory:
android list avd
This listed the emulator images. In my case it listed two:
Available Android Virtual Devices:
Name: titanium_3_WVGA854
Path: C:\Users\xxx\.android\avd\titanium_3_WVGA854.avd
Target: Android 1.6 (API level 4)
Skin: WVGA854
Sdcard: C:\Users\xxx\.titanium\android.sdcard
---------
Name: titanium_8_WVGA854
Path: C:\Users\xxx\.android\avd\titanium_8_WVGA854.avd
Target: Google APIs (Google Inc.)
Based on Android 2.2 (API level 8)
Skin: WVGA854
Sdcard: C:\Users\xxx\.titanium\android.sdcard
In my case I wanted the Android 2.2 API so I entered
emulator #titanium_8_wvga854
its only a problem of computer memory, sometimes when we build again and again by eclipse or other IDE, it consumes memory (don't know why maybe because of leaks) and it memory is user 90% , so that sometimes it creates problem for emulator launching and takes a lot of time to get launched.

Running Android emulator version 10.0 (build_id OPENMASTER-104271)
Kill the emulator which cause a dumprep.exe which I killed too.
You just need to resave the AVD configuration. Perhaps something got corrupted
In eclipse > Android SDK and AVD Manager, select your AVD Name and click Edit ...
Click Edit AVD ( resaves your settings )
select your AVD Name and Click Start...
Disabling Host GPU in the settings for the AVD worked for me. This was a problem for me with 2.3, but not 5.0.
