When I am starting the AVD from Android Studio, it shows a black blank screen for a LONG time and I do not see the home screen. I looked at a couple of Stack Overflow posts (Virtual Machine Acceleration for Android Emulator and Android emulator system images and AMD processor) from pre-2013 which suggested that it is because of AMD processor (which I am using) and which does not allow installation for HAXM.
I just want to know that since 2013 has there been a solution to this problem (either from AMD or Google)? Or else what is the alternative apart from Genymotion?
PS: In some example on the net I have seen the same blank screen but with a keyboard on the right, below the arrow controls.
PS: AVD does not even work when I select "Intel Atom x86" or deselect "Use Host GPU".
From memory, I think HAXM only works with Intel chipset, not AMD. (I have AMD, too!).
Genymotion is a good alternative to Android stock AVD, in terms of speed and startup. However, Genymotion does not support some API levels. So, depends on your requirement, you may need to use both Genymotion and the Android stock AVD to test for different Android API levels.
Also, with stock Android AVD, have a look at this link to see other parameters that you can provide when running an AVD. In particular, the -debug-all parameter can show debug logs that can help troubleshoot problems with an AVD. Unless you're testing sound for an app, there's no point loading audio support for an AVD. You can disable audio support by supplying the -noaudio parameter.
It is very likely that 512 MB is not enough to properly emulate an xhdpi device. Try increasing the emulated RAM to at least 1024 MB and see if you can boot properly.

HAXM Enabled version 7.1.0 and i verified that it's working when the emulator is running
The emulator is using the Nvidia GPU however it's barely using maximum 7% of the GPU at any given time
I have 27.3.1 of Emulator version ( Latest )
Tried x86 image and x86_x64 image
I tried hardware acceleration
I tried software acceleration
I bumped the emulator ram to 4GB (I have 20 GB)
I set the emulator CPU priority to real time
I have NOTHING but Android Studio, and emulator running
The emulator is running horribly slow and laggy and even gives a black screen when going from activity to another
This has been the case since forever
I tried deleting the entire Android SDK and installing from scratch
I have intel virtual technology enabled in BIOS
I tried Google Apis vs none Google Apis emulators
I tried Nexus 5, X, Pixel 1, 2, XL with android P, O, 16 and all laggy
This is what helped me with my Android 9 emulator:
Use Google Play x86 image instead of Google API x86 image, because the former had a notification "Preparing for setup.." which never finished.
After launching the emulator first time, going through the initial google device setting (skipping what can be skipped..) and setting up the SD card (as an external storage).
If there are some app updates running, wait for it and then force quit 'Google play services' app. If the emulator will be slow again after reboot, you might want to do this after every launch.
Disable mobile data in settings, because it was trying to connect again and again, using up all CPU. And CPU helps with rendering, so if there is no available CPU, it gets slow.
Edit:
5. Go to emulator Settings/Advanced and set OpenGL ES rendered to Desktop native OpenGL and OpenGl ES API level to Renderer maximum and reboot the emulator. In my case, using autoselect/autodetect had far worse performance.
-- this is a follow up for my comment above (it's too long to be written as a comment) --
then we established that the problem is coming from your compute (or your OS) - If you're using a Laptop make sure to check the settings of the laptop performance when plugged and when you're using a batterie. In case you have a desktop check also the settings if there is some sort of limitation set by the OS. That can happen to avoid overhitting and loud fan noises. If any of the above doesn't work and you still really wanna figure this problem out and I'll assume you're using Windows 10, then install Ubuntu or any other Linux distribution as a second OS just to try things out. If The problem is solved then you definitely need to change some settings in your windows.
For anyone looking for an answer. I simply updated windows 10 to a newer version and update my graphics card drivers and the emulator is insanely fast again.
I had the same issue on my laptop and also on my high-end PC. I tried everything I could find on the internet:
updating HAXM to the latest version (in SDK Manager)
disabling Hyper-V on Windows
disabling audio in emulator
disabling multi-core feature
changing the renderer
disabling snapshots [1]
Now, I cannot be 100 % sure that anything from above could not somehow contribute to fixing the issue (even that I changed most of it back), but the issue disappeared immediately after I did this:
Go to SDK Manager -> Install the latest SDK Platform
There is said in Android Developers User Guide [1] that these are the requirements for Graphics Acceleration:
SDK Tools: Latest release recommended (version 17 minimum)
SDK Platform: Latest release recommended (Android 4.0.3, Revision 3, minimum)
Even that I did have SDK Platform version 27, for some reason I believe that HW acceleration was not working, cause even moving the emulator windows was laggy (or even its settings). As I said before, latest SDK Platform version seems to be the thing that fixed it.
Also, do not forget to kill all emulator processes and also Android Studio. But maybe restart the whole computer just to be sure (I was doing it a lot, cause I was also checking a bios virtualization settings few times).
If it won't work for you, try turn off the snapshots as that was the last before I tried this. You will have to wipe the data from that image, or even better - create a new AVD and download the latest image from "Recommended" tab.
Hope this will be helpful to someone as I did spend several frustrating hours fixing it (after few months of living with it).
Disabling mobile data is one way that works if you're not connected already to data (regardless of wifi connection), another debugging tool that could help you is the FPS Meter in the Debugging Options in Android, relevant github guide
If your emulator is SUDDENLY slow, this might be the reason:
I ran through the same issue.
I then realized that it was a picture quality issue.
So if you're using a lot of pictures in your app, it will run slow unless you 'lower the picture quality'.
You can use http://compressimage.toolur.com/ to reduce your image quality.
I am using Android Studio, my system does not support emulator and I don't have any android phone but I want run android application. Is it possible to run android application without emulator and android phone?
You will always need to deploy your applications on Android OS which is only possible on an emulator or Android-phone when developping native-apps. If you're developing hybride applications, you can run your app in a browser and use browser-plugins to simulate the native features of your device. Please keep in mind that there is more than 1 emulator available for Android. The emulator in Android Studio is one of the slowest available. Try using genymotion or BlueStacks, but preferably, Genymotion.
There are different emulators. You can try installing Genymotion. You need an emulator or an android phone to run your app
No. It does not make sense that you would be able to do so, every application for any device needs a platform to run on!
More importantly, why do you say your system does not support emulators? There are many free emulators available online, I personally recommend you try Genymotion.
UPDATE: My guess is that the error you are getting is due to your computer hardware not supporting multiple CPUs such as those found in modern android phones. It might be possible to turn on hardware virtualization in your computer BIOS (usually you press F2 or some such when you are booting up - but this depends on your particular hardware).
The very first thing I would try before anything else is to download Genymotion (as it was also recommended by the other answers), and at least one other emulator before giving up. Have you tried any other emulator other than the default one that comes with Android Studio? Different emulators likely work differently and they might not need hardware virtualization.
If you are unable to use the HAXM based emulator or Genymotion, you are better off buying a handset device.
Otherwise you are limited to running the ARM based emulation which in the SDK manager looks like 'ARM EABI v7a System Image'. The ARM based emulation should be used with GPU acceleration enabled. Best possible performance would be to use the smallest screen possible such as 480x320, 800x480 or 854x480. The larger the screen in terms of pixels, the worse the performance.
Again the best recommendation is to get a Android phone/tablet and do your development there.
I am working on an android application, uing eclipse IDE. However it takes around 10-15 minutes to load my AVD and run the application.
My system Configuration:
RAM 8GB
intel Core2Duo Processor 2.53GHz.
OS: windows 7
Is their any alternative to increase our AVD's speed, without changing my systems hardware configurations.
You can setup an Android Virtual Machine using VirtualBox :

And to deploy to the virtual box :
android emulation on virtual box in eclipse
I tried this a while back and it was quite a performance improvement difference. I haven't done this in a while because I bought a pretty high end phone and I just use that now.
Is their any alternative to increase our AVD's speed
Using the x86 emulator will help.
That being said, your computer would appear to have issues. With that configuration, even the ARM emulator should take at most a minute or two, at least on Linux. Windows 7 perhaps adds some more overhead, but I would not expect it to be that much.
Also, bear in mind that you can usually keep your emulator open all day -- you do not have to exit and restart the emulator for most work.
GenyMotion have an Android Emulator that is pretty rapid. (not an AVD)
http://www.genymotion.com/
Genymotion is an emulator using x86 architecture virtualization,
making it much more efficient!
Taking advantage of OpenGL hardware acceleration, it allows you to
test your applications with amazing 3D performance.
It's free for personal use, has preconfigured devices (like N7 or Samsung GS3 etc).
I think you'll really like it.
You can select the snapshot options. On the first next start, a snapshot will be created. This will improve the launch speed of the emulator every other start...
To increase performance, I want to allocate 1024 MB RAM to a tablet emulator. Problem is that it won't start, i.e. no windows/consoles show up when I click Start in the Virtual Device Manager. If I let the device to its default 256 MB, it starts. How can I fix this?
I'm using Windows 7 Ultimate with Intel i7-2.2 GHz and 8 GB RAM DDR3. It used to work fine on 32-bit windows.
I know this isn't an answer to the particular question you have asked, but it may help with the underlying issue: you can increase the performance of your emulated device by switching to an x86 version.
The Android emulator has always been painfully slow for me, even on a quad core rig with 8 gigs of RAM, so I started following the Android x86 project. Not long ago, I finally took the plunge into getting it set up, and it was easier than I expected--and it's really, really fast.
If you have VirtualBox installed, all you have to do is download eeepc.iso from the project's website (for whichever Android version you prefer), create a VM for it in VirtualBox with however much RAM you want it to have, and boot it up. Pick VESA mode from the menu, disable mouse integration on the VM, and skip the google account login process. You'll be good to go.
Then just set up port forwarding for ADB from guest:5555 to localhost:whatever-port-you-choose, and point ADB at localhost:whatever-port-you-choose, and it'll work even better than the ARM emulator that ships with the SDK.
I disabled the camera support and I was able to use 1024MB of RAM.
I have installed Android SDK on my computer. I have a intel i7-2600 processor and a Zotaxc 460 gtx fermi and 12 gb of ram. Basically saying, it shouldn't be running slow. Any suggestions on how to speed up the apis? or is it just slow?
Assuming you are referring to the Emulator and not Eclipse or something, you can speed up the Emulator a bit by choosing a smaller screen size for the virtual device, like HVGA instead of WVGA, etc. But that only goes so far. The emulator is just not very fast right now. They are working on it, however. I believe they show some of their early work in this Google I/O session.
If you mean the AVD (the android device emulator) is running slowly, then it is behaving as expected. Perhaps you have an android device you can plug in and run your app on? I would recommend you download developer drivers for whatever device your using instead of the bloated ones they try to get you to download.
Good luck.
Here is some usefull question that is about speed of android emulator:
Why is the Android emulator so slow? How can we speed up the Android emulator?
Eclipse performance can by improved by setting eclipse.ini. For example I have set -Xms512m
-Xmx2048m. Without this options, Eclipse has too few memory to open my project.
Disable the boot animation with -no-boot-anim, "Disabling the boot animation can speed the startup time for the emulator."
