I have Android Studio and 8GB of RAM. The emulator takes about 7 minutes to boot, and anywhere between 1-5 minutes to install and run an empty project. Several errors like Emulator: sockettcploopbackclientfor: error: fd _____ above fd_setsize (_____) popped up. I am also using a Nexus 5 with an API 25 to improve disk, memory, and CPU usage.
I know someone who has uses Xcode and needs 16 GB of RAM, equivalent to a Terminator bot, and the apps and emulators work fine. How much RAM do I really need for Android Studio? Is it even a problem with RAM?
(And yes, virtualization is on.)
For me it was really slow that I was running the app and go to do something else
Sometimes it took 30minutes and I used to use 4GB-6GB ram for it .
Now I am using a real device and it much faster.

I have MacBook Pro 15 with 16 GB Ram. I am just running one project in AndroidStudio and it takes about 6 GB of RAM and make my MacBook slow. This is insane something is terribly wrong with AndroidStudio 3.0.
Please look at the screenshot it has two instances of java taking nearly 3.5 GB of RAM without emulator.
Is there a solution for this issue? I know about this https://developer.android.com/studio/intro/studio-config.html#low_memory but I have 16 GB RAM it should take care of things smoothly without tweaks.
For some reason, Apple limited the RAM capacity of MacBook to 16 GB and Android consumes most of it which is making me frustrated because I can't upgrade the stupid RAM or fix Android Studio memory problem.
For MacOS:
You can use ulimit buildin shell command to limit the use of system-wide resources
You can learn more about ulimit command here

Recently I have decided to start developing mobile apps for android. I installed 4.1 - version of Android SDK.
When I start the emulator I just got black screen and nothing starts. I have chosen different settings but nothing else is happening. My computer is running Ubuntu 10.04, 256 MB Ram, 1Ghz processor, 32 MB Video card.
I know this is not normal computer for these days. So I notice that when I make new AVD on Eclipse indigo ram is set to 512MB so this is my question:
Is this the problem and if it is, please help me solving it? (will everything be alright if I install different version of android).
Give me suggestions for solving it. I am praying for starting the AVD.
Take a look at the recommended system requirements. 256 MB RAM is way too low. Seriously, my phone has more RAM :)
I'm having a recent issue since two days ago. Before that I was running the android emulator (API versions 8 y 15) without any significative delay. But since these two days the starting up of the emulator has turn into unbearable time delay, the fifteen API version lasts around two hours, and the eight API version could delay more than 8 hours.
I have tried to reinstall the SDKs, erasing the AVDs without results. I have enabled the snapshot option, but the mentioned delay keeps the work awfully slow.
Thanks in advance.
try to use the following:
emulator.exe -cpu-delay 0 -no-boot-anim -avd avd
or to use gfx acceleration
emulator -avd <avd_name> -gpu on
if that wont work, give http://www.android-x86.org/ a chance ;)
As u already enabled the snapshot option, I dont have to name it again.
Furthermore:
Can I tweak my android emulator to make it fast?
Why is the Android emulator so slow? How can we speed up the Android emulator?

Unbearably slow android emulator -- is there a fix?
Your startups are taking hours? Something is seriously wrong. I'd check your development machine to see if it is out of disk or fragmented or thrashing. Maybe check that the AVDs aren't declaring too much virtual SD.
It's much faster if you run Android on a virtual machine. You can follow my guide on setting it up, here http://www.bobbychanblog.com/2011/07/faster-android-emulator-alternative-using-virtualbox/
I do not know what to do. I purchased a new laptop, hp pavillion i5 6GB RAM, started Android 3.2 emulator and it is still as slow as unusable!!!
It's not that it is slow, it's that I cannot do anything.
I set 1GB of RAM, disabled camera on emulator and run it. When I click on Applications, they first load for 30s and then I am not able to start any app, not mine, not default ones. All I can do is return to desktop and open Applications menu.
I see people complain that the emulator is slow and I am not even able to make it run. What is worse, my laptop eats games like a sandwich, but it chokes with Android emulator 3.2. The same is with Android 3.0 emulator!
Can anyone help me set up the emulator so that I can run it on my machine?
PS. if you want, I will record a video and post it to visually see what I am talking about.

The Android emulator uses a single core. If you had gone with a Core i7 with Turbo Boost, that would have helped. Your Core i5 is not an especially powerful CPU on a per-core basis.
The Android 3.x emulators also do all graphics purely in software (no hardware graphics acceleration) and convert ARM instructions to x86 on the fly.

Start by using the Android 4.0 emulator, with the latest Android development tools. This uses your desktop's GPU for graphics rendering, and it helps performance a bit.
If that proves insufficient, you can start switching to x86 emulator images if you are not doing NDK development (where you will tend to want to test on ARM). At the moment, the only official x86 image is for 2.3.3, but there is an unofficial one for 4.0.3 built from the AOSP that runs exceptionally fast (at least on Linux, haven't tried it on Windows).
My only suggestion to you would be to change the "ADB Connection Timeout (ms)" in Eclipse under Window->Preferences->Android->DDMS. I am using a HP Pavillion 486 laptop, and was really struggling with the emulators. I changed the default timeout value from 5000 ms (5 sec) to 60000 ms (1 minute). This didn't solve all of my problems, but it did help in the startup of both the emulator and my applications.
My experience with the Android emulator is that it is so slow that it is unusable. I see threads related to the issue going back over a year. The lack of a coherent response to the question is unacceptable (this is not the Community's fault).
Question: Has anyone that has experienced extreme slowness (more than 15 minutes to launch) actually resolved this issue so that startup is less than a couple of minutes? If so, what did you do?
Please note that I am not trying to tie the emulator to Eclipse. I am teaching mobile web app development using jQTouch. The web apps are testing by running the emulator standalone and opening the Browser.
While my machine is a little dated, I have no trouble running Vista, Office, PowerStudio, etc. Here are details to add to the data around this issue.
OS: Microsoft Vista, 32-bit
Processor: Intel Celeron M CPU 520 # 1.60 GHz
Memory: 1.5 GB
Symantec Antivirus - Disabled
Emulator Start with no animation - did not help
Startup time in excess of 20 minutes
Java Version: 1.6.0_21
AVD Settings: Device RAM size 1024, Snapshot support enabled both in AVD and startup. - ram size and snapshot did not help
Google needs to acknowledge the issue and provide guidance about what development environments actually work. If there were a recommendation for platform, java version, memory, etc., I would follow it.
Right now I have no options other than to tell students that the Android emulator doesn't work. The only android solution is to buy a real phone, which limits testing to a single Android version and configuration.
Students are not having trouble with the iOS simulator running on the Mac.
If someone that works for Google could actually comment, that would be great.
Thanks,

The Android emulator is just that, an emulator -- it is emulating an ARM processor. Emulation will never be as fast as native. Given you are using such a large amount of your computer's memory for the emulator, you are likely having to page consistently, which will add to making the performace suffer.
The iOS simulator on the other hand is just a set of APIs that matches the iOS SDK and pretends to be an iOS device, but is running all code natively on the machine with all the resources, processor speed and memory the machine has, and likely to run significantly faster than running on the actual device.
I have no problem running the Android emulator on my old Core Duo T2400 # 1.83GHz with 2GB of RAM. The startup time can be a few minutes, but once it is running it works well with only occasional lag.
My desktop with a Core 2 Quad Q6700 # 2.66GHz with 2GB RAM tears through the emulator.
Both machines have run the emulator under Windows and Linux with varying Java versions getting similar results. My guess is that your processor is a little on the weak side.

Or in brief, download an android-x86 build here, install with virtualbox, find ip address of android vm by alt+F1 and netcfg (alt+F7 to go back to graphical mode), and connect to the vm using adb (say adb connect 192.168.1.5).
Just used it, much more faster.
I've found the emulator to be very slow too - I think it's best to have a working android device and just have the emulator for a backup 'second opinion' or a reference device. It's usable but much slower than my phone, even though my current device is quite low end.
Eventually, I found that sending my code to the physical device (or emulator) was becoming a bottleneck so I build a small framework to allow me to develop most of the work as a desktop application. This has worked very well so far and has sped up my development turn around considerably. Your milage may vary.
Try using Genymotion emulator for android which is fast and also support all major platforms including Linux/Mac and windows. It also has specific emulator image files to emulate actual mobile devices like Xeperia Z or Nexus 4 and so forth.
Use Genymotion. It s is a very fast android emulator.
Android emulator is just a emulator, it emulates an Android device. It's like virtualization, you share your computer's resources with emulator, you'll need to have the latest processor and at least 8GB or RAM to run faster. About RAM: Windows and background programs consumes a part of your resources, if you upgrade your computer resources, the consumption of these software will be almost insignificant and you'll have a lot of resources for your emulator (supposing you also have Eclipse or Android Studio running).
