Why is the Android emulator so slow? How can we speed up the Android emulator? [closed]

I've got 4GB of RAM memory #800mhz, Phenom 9750 x4 #2.4GHz, yet the emulator is working really slow. I'm currently learning the basics of Android development, so I wonder, what should I do to maximize the performance of the emulator? Which device do I pick and what should be the settings? I do realize my PC is outdated and slow, but surely it can do better?
Make sure you aren't emulating another architecture in your settings. Choose Intel instead of any others and try again. I think you have to create a new device but I'm not certain.

In my company, they did not provide a phone for deployment or running the android project, so I'm forced to used my SAMSUNG GALAXY S 4. What are your suggestions? Should i buy a cheap phone only for debugging/running android apps or is it good to use my own phone? I'm just worried that my phone will be damaged for continued spamming uses of it.
What should I do?
There is nothing to worry about using your own S4 for company purpose unless until you need to root your phone. Really Rooting is not a bad thing to worry about it. If you've a android project that needs to check Camera and Sensors then you should use a real device, But still there is an alternative to avoid using your own S4.
There is an emulator called GenyMotion, Even if you want to check camera or any other kind of sensors you can use that emulator to all the stuff. If you've found your emulator to be damn slow, I suggest you to use the GenyMotion, which is 10 times fast than the ADT emulator or else there is one more alternative to use a faster emulator with INTEL HAXM which is same as like GenyMotion for faster emulator.
Chill :) Happy Coding
It is difficult to actually mess up your phone with an app due to how apps are sandboxed. This is especially true if your app remains at the SDK abstraction level, and doesn't mess around at the OS level.
If you're afraid that will damage your USB connector, you can use Wifi ADB to connect ADB via wifi, but you must have your phone rooted first.

we have developed a video player using videoview and media controller. When videos running in android emulator(Android 4.4 API level19) it getting lagged and some scenes in videos were also skipped. Kindly give some suggestions regarding this.
thanks in advance :)
It is not an issue.
As we know android runs on arm processor.
When we run any application on emulator what happens , emulator is a virtual device which is running on desktop processor(e.g intel).
So every statements execute by emulator need to convert from intel understanding format to Arm understanding and result of executed statement to Arm to intel.
Because of this conversion take place for every byte emulator seems slow in terms of performance.
So don't worry it will smooth in real device.

is it my computer's hardware limitation? it has 1024 megabytes of ram 2200 x 2 dual core amd cpu i can't develop any android. the emulators are heavy what can I do? i download old sdk and newer ones but it still the same.
You could try using the x86 (Atom) system image it's faster than the arm images
See this link for more info
I have much better PC than you and even I have difficulties with emulating some OpenGL ES applications that I develop for android.
You must understand that emulating a CPU which is different than current architecture is very hard to do and as such very hard to do very optimized. Running machine code for ARM on x86 must bring some delays in running it. Conversion and repacking back and forth.
I would rather try to use your own Android device for testing and debuging purposes instead of emulator. It runs in real time and it will be better for you if you don't want to upgrade your CPU and RAM.
1 gigabyte of ram isn't enough. Eclipse alone would take up almost a two-thirds of that
(mine takes up 900mb - tweaked in eclipse.ini), and a 2.2 Emulator on HomeScreen would take up about 200mb. Unless you don't open anything else while coding - firefox, chrome (that ram sucker of a browser), mail client, chat client, etc., you're only a pinch below the limit.
The best you can do outside of upgrading memory is to run emulator in QVGA (in AVD Manager, click on your virtual device, click edit, under Skin, change Built-in to QVGA. But it would only do so much - you need at least 4 gig to go smoothly with all other apps open.

Why is the Android phone simulator so slow?
Hi, I am new to Android development, and I wonder why the Emulator loads so slowly, especially when I create an emulator for Android 4.0 apps.
Usually this is tied directly to the speed of your development system. Increase the amount of RAM, disk speed, processor cores etc. and you'll see a noticeable improvement.
Also, check out this question for some more information.
It's slow because it runs Android on emulated hardware (an ARM CPU, IIRC). So you're running a complete virtual machine, not just a sandboxed OS. And since it emulates a single-core machine, having multiple cores on your development box doesn't help much. You're better off with a dual-core 3.5GHz machine than a 4-core box running at 2.5GHz.
Android Emulator is the virtual Device of android OS. It takes ram and Memory from the host OS that why the ram and the memory is shared by the Emulator.
As because it is slow in process.

My tablet is not here yet, which is why I have to use the emulator for development for now. But it is soooo slow, and it is almost not usable. Does anybody has any trick to speed it up a bit?
I am working on a very decent machine:
MacBook Pro, 2.4 Intel Core 2 Duo, 8G Memory, SSD.
Thanks
There are a number of answers to a near identical question here.
It is slow because it is emulating an ARM processor on an x86 machine. This means that:
All hardware acceleration is lost and has to be emulated in software, and
All the system calls have to be restructured.
Google is working on better ways of doing graphics, but nothing is released yet.
There are no tricks as of yet, and no other Emulators that you can use, Until Google actually makes one.
Thank you

I know a trick. Upgrade to a better CPU, preferably one not subject to laptop limitations.
