My laptop: Intel Core 2 Duo CPU, 2GHz, 1GB RAM.
I created a target with SD Card 512MB, Device RAM size 512, snapshot enabled. I waited for 30 minutes but the emulator doesn't ends up loading. It keeps showing a flash word "Android" on the black screen.
Before running the emulator, I closed most other programs.
What's wrong with it? This is very frustrating. :(
What is your CPU and RAM usage during startup? Do you have a lot of IO swapping occurring? Considering that Windows needs at least 512 to run right half of the time and Eclipse is a memory hog you probably just need more RAM.
It shouldn't take more than 5-10min at most to build the emulator on initial startup. The SD card size has no effect on memory usage, it's not loaded into memory, it just creates a larger image file for the sdcard. Setting the emulator to have 256mb of ram will help, but in general when I have the same problem I just close down the emulator window and re-start it. Sometimes it just gets hung-up on creation and isn't a memory issue (I have 16gb of ram and still have the problem from time to time)
You're assigning the emulated Android instance half of the physical memory on your machine. Get more memory.
Emulator is in general very slow, and the higher the OS version on the emulator, the slower it gets. I'm a game developer, and with my AMD Athlon X3 2.90 GHz with 4GB RAM it gives me 5-6 fps. I tried to open one of my apps on Honeycomb emulator, and it was really terrible. It opened, but I couldn't do anything with it. So the best answer is purchasing a real device.
I've experienced the same thing and in my case I had to set "Min SDK Version" when creating the project in Eclipse. Without this setting the emulator didn't start.
Android Development Tools (ADT) 9.0.0 (or later) has a feature that allows you to save state of the AVD (emulator), and you can start your emulator instantly. You have to enable this feature while creating a new AVD or you can just create it later by editing the AVD.
Also I have increased the Device RAM Size to 1024 which results in a very fast emulator.
Refer the given below screenshots for more information.
And for speeding up your emulator you can refer to
Speed up your Android Emulator!:
The native Android emulator is really slow. It's much faster if you use Android on a virtual machine. You can follow my detailed guide on setting it up. http://www.bobbychanblog.com/2011/07/faster-android-emulator-alternative-using-virtualbox/

I'm using a Windows 10 machine with Intel Core 2.20 GHz processor (x64-based processor) and 8.00 GB of RAM and I've assigned 2048 Mb of RAM to the emulator.
So, in my understanding the machine is not that bad to run the emulator quickly. But, emulator response time is too long and also utilizing 80% of CPU, 95% of Memory and 100% of Disk.
Also, tried to assign less RAM from AVD manager to the same emulator but still the same issue and sometimes only white screen is appearing on the android emulator. I have android studio 2.3.3 and already tried to enable/disable the "Instant Run" from the settings but no success at all.
So, is there any possible way to fix this issue, or at least want to know why speed/performance of an android emulator is too slow instead of some external emulator such as Genymotion.
I've spent days on internet and on stack overflow but couldn't find a similar issue/solution and didn't understand the reason of slow performance of android emulator.
You can use Nox Player App and use it like hardware device. You will be able to debug your code as well.
Android Emulator takes from 15 to 20 min to start up and mostly crash thereafter on my Laptop no matter what kind of Android mobile or setup Im using. Im one a total lost on what i could do to make it run on a usable level.
Im running it in windows 8 on my labtop with 8 gb ram and a AMD quad-core on 1.6 GH.
Make sure you've installed the "Intel x86" system image for the API level platform you're using and then make sure your emulator is using that in the CPU/ABI dropdown in its configuration.
That will speed it up significantly over using the ARM image.
The only other thing you can try is to use snapshots, then you'll only have to sit through the long start up once. Snapshots have always been kind of glitchy for me though and I've stopped trying to use them, which reminds me, if you are using snapshots, try turning them off, that might help too.
This also happens to me when trying to run a full-spec device. I lower the specs and resolution quite a bit since I don't even have enough memory to allocate for a 1GB ram virtual device.
The first boot will take some time. You can configure your emulator to use snapshots which will speed up the boot time considerably. Look into running the x86 image which will increase the performance of your emulator. Keep in mind if you have any armeabi-targeted binaries, they will not work (not an issue for most people).
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."
I'm beginner on Android applications. I followed the steps in tutorial and prepared development environment on Vista (Eclipse Helios + Android SDK 12 + JDK6).
I created a minimal AVD with 32mb SD card and 128mb ram, enable snapshot.
and set current AVD in run configurations of application as automatically.
Emulator is extremely slow and CPU usage 100% shared by eclipse and emulator,
memory consume is also in limit.
Do you have any suggestion to optimize it? It's my first step in development android app, and i don't want to be discouraged.
Thanks a lot,

You can use Bluestacks App player or Youwave For Android.
Those emulators are very much faster than eclipse emulators. You will find that they are most likely runnning your app on a real phone.
Emulators use significant resources but with a medium computer it should run ok.
Try creating a new emulator instance with default settings, HVGA and no snapshot and no sd card.
Use android 2.2 for this test.
This one should run pretty smoothly on a medium computer.
Let us know the results.
As everyone else has stated, the emulator is terrible for testing. I'd suggest debugging on a device, even if that means only being able to test one API and screen size.
Launching from a snapshot is also a way of cutting the loading time and resource load on the CPU. I found it to still take a considerate amount of time still, but it is less than half of what it took before.
you can download and install genymotion virtual device,, it is 3x faster then normal AVD
