Slow Android emulator
I'm running on Eclipse Helios on Windows 7 x64. I have a Core 2 Duo 2.0 Ghz with 4.0 GB which I think should be enough, since I've never have any performance problems with developing tools.
When I run my first app on the Android Emulator (both 2.3.3 and 3.0) it took at least 5 minutes to load the OS and at first it didn't even run the HelloAndroid app. Even when I managed to run the application, the performance was unbareable.
The strange things is that is not a OS performance issue. This is the CPU and Memory status while executing:
I've tryed various things to improve the performance, but no major improvement is shown. I think I'm missing something.
Things I have tryed:
On AVD Manager
Device RAM size to 512.
Resolution to 640 x 480.
Snapshot enabled.
On Project preferences\Android
\Launch\ -cpu-delay 0 -no-boot-anim -cache ./cache -avd Android3
Things I can't tryed:
- Deploying on a device (don't have any).
By the way, I've had the same problem on a MAC Mini 2.66 Ghz 2 GB but these settings made the difference.
Anyone can give any tips to improve this lame performance?.
Unfortunately, you are not alone on this.
There doesn't seem to be a good solution, but a few tips:
Start the AVD directly, not through the IDE
Leave the AVD running instead of closing/restarting when you change code
Debug on a real device. Yes, you lose testing on multiple versions and resolutions, but for many of us, it's the only bearable solution.
Hope this helps a bit...
I had the same issue, the emulator would freeze at "android_". I fixed it by changing the compatibility mode on emulator.exe to "Windows 7". Now it's always slow, but it's running.
Open taskmanager and right click on emlulator-arm.exe (*32), klick processor affinity (affiniteit instellen) and select (if you want ofcource) or just select te cores you want to use. Increases the performance a lot for me (with eight threads available)!
My performance issue was mainly caused by the resolution of the Emulator. I set the resolution to one of the default values of the emulator resolution and it's working much better. I wouldn't say it works as good as the iPhone simulator, but I can work with.

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.

Why emulator is very slow in Android Studio?

I know this is a common question, but I feel like I've tried every single solution out there, so I don't know what to do anymore.
Intel x86 HAXM is installed
Tried Reinstalling the emulator in the SDK Manager
Tried various AVDS with different API levels
Whenever I start my AVD, it will take about 10 minutes for the android sign to pop up, then it will remain for another 10 minutes and then eventually say the process has stopped. Sometimes it will launch and run fine, but it seems the initial startup just takes a brutally long time to the point where it's not worth to test any apps on it.
I don't understand what's wrong, and have been extremely frustrated with this situation over the past 2 days, any help or tips would be appreciated!
Install Genymotion, Every single device/API version they host is relatively quick GenyMotion Android Studio Plugin
visit Why is the Android emulator so slow? How can we speed up the Android emulator?
Try low settings for faster open up Recommended
1. use intel system image
2.Screen size 5.0 or below
3. Ram size from android 5.0 is 1gb and above. if you have 4GB ram.
4.Increase Ram size on your computer or laptop default 4Gb and above for faster run
The emulator's performance has a lot to do with your specs and the specs of the emulator itself. I used to face the same problem, but I upgraded my ram and emulators of all types run pretty fast now. Another alternative is to use your device to test. As far as geny motion is concerned, it turned to be slow too. Its just my personal observations though.
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.

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.

Need information about minimum hardware requirement for better experience in developing Android application.
My current configuration is as follows. P4 3.0 GHz, 512 MB of ram.
Started with Hello Android development on my machine and experience was sluggish, was using Eclipse Helios for development. Emulator used to take lot of time to start. And running program too.
Do I need to upgrade my machine for the development purpose or is there anything else I am missing on my machine(like heavy processing by some other application I might have installed).
And If I do need to upgrade, do I need to upgrade my processor too(that counts to new machine actually, which I am not in favor of), or only upgrading RAM will suffice.
Firstly, there is an issue with the ADT plugin and Helios which causes lag with looking up Android classes - use Galileo instead (v3.5).
Secondly, the emulators become more resource hungry depending on the version of Android you're developing for. Example, I have a P4 2.4GHz, 1GB RAM PC with Win XP 32-bit and an Android v2.2 emulator takes at least 4-5 minutes to load up. An Android v1.6 emulator on the other hand loads up in less than 1 minute. Remember though that once the emulator is up and running, you can leave it loaded and it will be more responsive than first use.
Also bear in mind that if you give your emulator a 2GB SD card (for example) it will try to create that through virtual memory if there isn't enough physical memory.
I did the following experiment at home:
let's compare how 2 computers compile the same android application in eclipse. Here are the competitors:
"the monster"
- pentinum i7
- 16 gig RAM
- solid state hard drive
"peabody"
- pentinum i3
- 4 gig RAM
The results:
when I compiled the same application in eclipse, the monster and peabody took exactly the same amount of time to bring up the emulator to the point where you have to slide the button to run the app: 1 minute 12 seconds.
After that point, the monster executed the app 30-40 seconds faster than peabody.
The monster costs about $500 more than the peabody. So the question is, is it really worth it? In my opinion, No. I can wait the extra 30-40 seconds
I use an i5 processor with 4Gb RAM. It works very well. I feel this is the minimum configuration required to run both eclipse and android avd simultaneously.
Just an old processor with high RAM is not sufficient.
IMHO it is cpu and RAM dependant. On my Wolfdale (with Intel virtualisation technology) + 4GB of RAM it's very fast and usable. As I know the emu is qemu based so it`s better to have Intel with virtualisation tech enabled and don't forget to insert any virulatisation modules to the kernel (if using linux).
Its of no use even if you increase your RAM size because I tried it too. I am using P4 3.00GHz processor and 3 GB RAM(changed from 1 GB to 3GB), But even the Hello world application never turned up.
Its preferable to upgrade your system.
I've just started using Java on Eclipse (Juno) after a 15 year break from Java. I was using the ADK on a 1.6GHz Atom N270 with 4Gb RAM on W7 32bit on a nearly empty disk. Not sure if it is the Atom or whether Java is as bad as it used to be 15 years ago but it takes over 2 minutes for Eclipse to even start. The emulator does turn up eventually but is extremely sluggish. Even without the emulator, Eclipse is sluggish.
On a 1.6GHz Core i7 or a 2GHz Core 2 Duo, operation is reasonable. Emulator works, Eclipse takes about 5 to 10 seconds to be ready for work. Moral of the story: don't use an Atom or any other low powered processor. It is sluggish even with 4Gb memory and having the same clock speed as a high end processor.
I've also tried it in a VMWare VM on the 1.6GHz Core i7 and on the Core 2. It is reasonably fast until the the emulator is started. It then slows down to the point of no return. Redraws is now very much like that of the Atom but at least it responds when the buttons are clicked. Note that it is now running an emulator within an emulator. The only problem with VMs is that every so often W7 does what W7 does. There is a wait cursor and whole machine is totally unresponsive for a minute or two then it springs back to life. This was with VMWare V3. V4/V5 might be different. Varying the number of cores/processors did not make any difference to eclipse or the emulator.
I use DUAL CORE 3-GHZ with 2GB RAM, windows 8 OS.
I can run eclipse and AVD (even running 2 AVD is still good) smoothly, as long as i dont open too much other tabs (Game, Browser, MS Word, etc).
Hey, I have used the same software on an AMD 3Ghz chip, dual core. had 2gbs of ram at the time, and i noticed the emulator ran at an alright speed, but took a ridiculous amount of time to load.
I have not done enough development on Android to tell you if this is a common, or even still existing problem, but it is certainly something I remember from my experience.
Have a look at the android SDK system requirements Here
I'm guessing some extra RAM would help your developing experience...Also the emulator does take some time to start on even the speediest systems.
I find identically-specced AVDs run and load far better on my home machine (Phenom II x4 945/8GB RAM/Win7 HP 64bit) than they do on my work machine (Core2Duo/3GB RAM/Ubuntu 11.04 32bit).
As you're essentially running a virtual machine, I would personally go for nothing less than a dual core/4GB, though highly recommend a quad/8GB if you can splash out for that.
