Why emulator is very slow in Android Studio?
(20 answers)
Closed 5 years ago.
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

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'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.
I have intel i7 quad core with 4GB of ram but when I try to run my app on the emulator, God it takes a hell lot of time. Some times more than 5 minutes. I am not emulating any game or graphics intensive thing. I am learning android so just trying simple aps but still it is very slow. Moreover today I found this emulator has stop playing any music or sound I used the in the programs, I made previously. What can be the reason of this weird behaviour and slow speed.
How can I fix it? I am on Windows 7
PS: when I try to type in an app from user keyboard, the emulator doesn't take any input unless I use the emulator keyboard. Can I change its settings to take input from keyboard.

Open android sdk manager, in extras, install "Intel Hardware Accelerated Execution Manager", and use x86 images (there are two available, one 2.3.3, one 4.0.3) provided by intel.
On windows, android SDK Manager only downloads the installer of IntelHaxm, so you have to go in and install it yourself. Usually you can find it under
android-sdk\extras\intel\Hardware_Accelerated_Execution_Manager and install IntelHaxm.exe as admin.
4GB of RAM imho is not enough, windows 7 and eclipse together takes more than 2GB out on my system. 8GB is minimum and the more the better.
The emulator has always painfully slow for me; I've never gotten any of the standard speed suggestions to work. However, if you have a device available, testing directly on it is much, much faster.
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 currently on a Windows 7 box with 1.83GHz processor and 1 GB RAM. I used be able to use all applications with no speed issues. I recently installed Android Plugin in Eclipse Helios and now Eclipse has slowed down badly. Running projects/creating projects/saving code changes all takes 3-4 minutes to happen. When the emulator is launched, it takes a good 10 minutes to be able to use my app. What is causing Eclipse to slow down ?? Wasting a lot of time on this. Please help.
Thanks in advance !
Your system should be running on the edge of the limit when you have Eclipse and the Emulator running. If possible work on a device or check the CPU/RAM usage while working. You should be able to see where the bottleneck is.
If you have Windows XP somewhere, I strongly recommend to switch back to XP...
Usually when your using programming envionments such as eclipse it is very taxing on your computer. The emulator taking up to ten mins to run is not shocking. I also had the same problem but if you have an android device you can use it to test your programs (its almost instant compared to the emulator.)

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.
