My Android emulator is so slow it doesn't actually display any my Android work!I've left it for an hour and came back to find nothing. I'd really appreciate any suggestions!
May be problem with your Memory...try to edit AVD just increase or decrease the RAM size..try to refer this link...here
Try to increase the memory. I would also recommend using a "common" AVD. Similar to here:
http://mobile.tutsplus.com/tutorials/android/common-android-virtual-device-configurations/
If that doesn't work i would strongly recommend getting an android device. There are a lot of cheap ones (especially from China).
But this is also a repeat question, see here:
Is there any way to reduce the boot up time of Android Emulator provided with android SDK
Probably your computer is a little bit slow for the settings.
I noticed that high-resolution emulator consumes a lot of resources. So basically run it with 340-400 resolution, works much faster. Hope it will help.
Try using Genymotion. You can download a version for Windows/Mac OS X/Linux after registering. A plugin for Eclipse is also avaliable.
i give you link Genymotion Emulator please download and setup.
as per my experience Genymotion Vertual device is faster then android emulator.

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.

Making the Android emulator run faster
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.
So i'm having awful trouble trying to get the Emulators in the Android SDK to start up. I can create the AVDs just fine, and then when hitting the 'start' button from the SDK Manager, bring up the small loading console window, indicating that the emulator is launching. However, after that, nothing happens!!
I have read many threads and posts with people having the same problem, maybe to do with the settings requiring too much memory, with some people waiting 30 minutes for the emulator to load!!
When trying to run the AVD emulator through terminal, I simply get a 'Bus Error' with no further indication of what could be going wrong...could it be a memory issue?
What I did to get where I am now:
Download the Android SDK package for Mac. I'm extracting the sdk only, not eclipse. I'm on Mac 10.6.8.
Install the SDK, and download the latest version of Android in the SDK Manager, along with default tools.
create a AVD and hit start.
window pops up to boot the emulator, that process is complete and window closes.
Nothing happens.
My knowledge of the sdk tools are very limited, all I want is to be able to do some testing...
Any help greatly appreciated!
Thanks
Actually, the simplest way to get emulators running right now is probably GenyMotion. They provide an interface, and pre-configured emulator images to make it pretty simple to get running.
This is not an endorsement (I use the standard ADT myself) but a lot of people find their tools useful.
Here is my suggestion: instead of using AVD, start using espresso and virtual remote android hardware emulator from Google servers - also known as android-test-kit. You will have the possibility to run and test you App on several different devices, without the need to spend money on actually all different devices for developing and testing purposes before releasing your Apps. You find further details here:
android-test-kit
Why Espresso
The 2 videos are somewhat long, but worth watching.
Taking this approach will solve your problem, save you money, and improve your productivity.
I run into the same issue on my mac 10.6 and it only works if i do
emulator64-x86 -avd my_android
Besides, my virtual device has to configured using x86 but not ARM
maybe this link can help you.
I have a celeron processor :/ and android emulator on eclipse uses 100% of cpu and hangs everything unless I kill it . I was just trying a hello android program from a book and don`t know much about android or even eclipse .I have the android-eclipseplugin installled .
Can someone help me with is ?thanks!
As others have said, the solution is disabling sound. Unfortunately, in recent Android Studio releases (I'm using 1.4) the option to disable sound has been removed from the GUI. To disable sound you can do it either by launching the emulator from the command line with the -noaudio flag, or by editing the AVD's config file and setting the following parameters:
hw.audioInput=no
hw.audioOutput=no
On Linux, I found that file at ~/.android/avd/myAVD.avd/config.ini
I've had the exact same problem and found a solution that works for me.
In the config of the AVD I've set an extra flag "Audio playback support" to "no".
I've also made sure the AVD has 1GB of RAM.
This worked for me.
For me, it was unchecking the Multi-Core CPU check box
Niels' answer worked well for me https://stackoverflow.com/a/7706018
in that the emulator stopped using 100% CPU (dropped down to 10-15%)
Furthermore it had another useful "side effect". I noticed that playing video in Totem or music in RhythmBox would block while the emulator was running. VLC would play video but refuse to play the accompanying soundtrack for the video.
As soon as the emulator was killed, music would start playing.
Niels' answer to set "Audio playback support" to "no" prevents this issue.
I am running Ubuntu 11.04 and Android emulator version 13.0 (build_id OPENMASTER-172639).
I had same issue on my macOS High Sierra and for me helps to create new AVD device and choose CPU/ABI = x86_64, not x86 in Android version dialog. Hope that helps.
The Android emulator is emulating an ARM CPU without hardware acceleration which can be pretty slow even on a core2duo for example.
You can try to reduce the screen resolution of the virtual device which should result in a small performance increase.
The emulator is notoriously slow to start; it can take 15 minutes or longer on an underpowered machine. You can speed start-up a bit by passing the -no-boot-anim to the emulator start-up command. Other emulator options are described here. Also, some AVDs start faster than others. Try creating an AVD with the lowest level SDK that is useful for you.
Once the emulator has started, you don't need to shut it down. When an app exits (or crashes, or whatever), you can just run it again.
One alternative that worths mentioning is Genymotion. It's an android emulator based on VirtualBox, with pre-created images. It supports some features the stock Android emulator isn't very good at, like Wifi 3G, Bluetooth, GPS (with a fancy Google Maps integration, so you don't have to find coordinates manually), multiple screens, etc.
It worth giving it a try at http://www.genymotion.com/
I had this issue running the emulator on Ubuntu 14.04. Disabling the audio does bring down the CPU usage, but in case you need audio to work, it can be fixed by adding a symlink:
sudo ln -s /usr/lib/x86_64-linux-gnu/libpulse.so.0 /usr/lib/x86_64-linux-gnu/libpulse.so
The reason for this is that the emulator tries to use pulseaudio as the backend, but will be unable to link to libpulse.so, which does not exist on Ubuntu (unless you installed the libpulse-dev package). Then it will fall back to ALSA, which constantly calls poll, causing 100% CPU usage.
A fix for the emulator is coming, but for now, adding the symlink solves the issue.
I strongly recommend not to use android emulator. Use VirtualBox + android x86 OS (you can download it here ), and you will get real perfomance increase.
Unfortunately, as far as i remember, it is not from google and it supports only Android 2.2. I really do not understand, why google is not going to make simulator as fast as iPhone simulator , or to make official x86 release for debugging. I do not need emulating ARM processor instructions and I think 99% developers do no need it too.
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.)
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,
Semanur
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
