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

It's well known that the factory emulator is extremly slow. The trick here is that the factory emulator needs to run on an ARM machine, so it needs to convert the ARM calls to your your x86 (or 64 bits) processor calls. It's likely to never run fast at all. In this situation, you may want to trust on the factory x86 images that make use of Intel's HAXM drivers, not available to everyone, and I couldn't manage to make it work myself, but it's useful to know that.
However! Since a while ago, I started using Genymotion's emulators. They rely on an actual virtual machine, which is way way faster than anything a factory emulator could achieve. Even if I'm running it on the lowest Mac Mini out there, it's pretty smooth. I'd personally give it a try (well, precisely, I gave a try)

Try allocating more memory for it to use. The Android Emulator is super slow as it is, but if you are not giving it enough memory it has the ability to never load.
Google emulator uses ARM opcode, a kind of machine language. It must convert from ARM opcode to Intel opcode. That's why it's slow. The problem seems not to be RAM but CPU. Improving CPU will improve the emulator.

If you are using your emulator in windows than you can use Microsoft Andriod Emulator.
Install microsoft android emulator in your windows os
If it is taking too much time in loading make sure you have installed the "HAXM installer" in SDK tools , Also make sure "Hyper V" option is also unchecked in "Turn Windows features on or off" in Control Panel --> Program and features.
Only After unchecking this feature you can install the HAXM installer.
After doing this the Emulator will not take time to load.
Try creating the Android virtual device with more RAM than usual. The usual is 1 GB. Even though I tried this on another lower end PC, it was still slow. I think it can be a problem with your hardware. Lower end hardware tends to have problems running emulators.
The problem seems not to be RAM but CPU. Improving CPU will improve the emulator.
I am using Eclipse new v22.6.2 . My emulator is starting and running very slowly... How to overcomes this problem..using 3.7"WQVGA(240x432:IDPI).
system configuration is 2GB RAM and 64 bit windows 8 and i3 processor
Increase eclipse Memory size since you emulator is using its memory to run. See here to give more memory.
Genymotion is the better option if you want to test your app with emulator.
In my personal opinion it is always best to test app with the real devices.
I recommend using Genymotion (https://www.genymotion.com/). It is free for personal use.
Just had this issue myself (even though I believe to have a nice piece of hardware) and found that it's really faster as it claims to be.
In my notebook, it will get up and running in about 20-30 secs. Hope that will suit your needs.
My PC is core i-5 with 4gb RAM.
whenever i try to run an AVD in eclipse it comes fast, if i want to run an AVD for TAB it take 5 to 10 minutes. Is there any way to make it fast? Also some time it comes with blackscreen says open gl es API problem type something
Also after fast run, i dont close it, i use it same AVD for all run. But it becames slower after every installation or run by my app. so i have to close and restart my AVD, is there any solution for it. Also some time DDMS cant find AVD, while it was running in font.
Anyone face these problem? any tricks?
one another thing, some time app dont run automatically after installation, i have to select app in AVD's APPS
The Android emulator does not make use of multiple cores. Whether you have 1 or 8 cores doesn't matter. However, the speed of a single core does affect the speed of the emulator.
Having a processor with TurboBoost helps considerably, in my experience. Additionally, it is well known that the 3.X and above emulators are extremely slow by nature.
You could also try allocating more RAM to the AVD in it's setup. Reducing the screen size and resolution also helps in speeding up the emulator.
You can refer to this Google Group thread for details on why the emulator is slow, and how to speed it up.
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."
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.

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/
