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.

Android Emulator takes from 15 to 20 min to start up and mostly crash thereafter on my Laptop no matter what kind of Android mobile or setup Im using. Im one a total lost on what i could do to make it run on a usable level.
Im running it in windows 8 on my labtop with 8 gb ram and a AMD quad-core on 1.6 GH.
Make sure you've installed the "Intel x86" system image for the API level platform you're using and then make sure your emulator is using that in the CPU/ABI dropdown in its configuration.
That will speed it up significantly over using the ARM image.
The only other thing you can try is to use snapshots, then you'll only have to sit through the long start up once. Snapshots have always been kind of glitchy for me though and I've stopped trying to use them, which reminds me, if you are using snapshots, try turning them off, that might help too.
This also happens to me when trying to run a full-spec device. I lower the specs and resolution quite a bit since I don't even have enough memory to allocate for a 1GB ram virtual device.
The first boot will take some time. You can configure your emulator to use snapshots which will speed up the boot time considerably. Look into running the x86 image which will increase the performance of your emulator. Keep in mind if you have any armeabi-targeted binaries, they will not work (not an issue for most people).
I am using the Android version 4.0.3 on a Windows system. My emulator was working pretty well, however all of sudden it became very slow.
It is taking too much time in launching so most of the time launch gets cancelled or I have to start the emulator ahead of time.
If you are having long times in emulator startup, you can configure AVD to save a snapshot of emulator. This significantly improves startup time, although the shutdown time will increase due to the saving of snapshot.
If you are having a slow emulator in general (booting and running programs), and, if you are using a Intel x86 processor you can install Intel Hardware Accelerated Execution Manager from android SDK. This will improve emulator speed by more then 10 times compared to the standard emulator. It even faster then a mid range real device.
good luck.
The emulators, all of them, on every platform, are infamous for slow startups. Typically you start the emulator, wait 'til it is all the way up, and then run your program. Debugging on a real device is infinitely preferable.
Leaving the emulator open between program runs is a necessity.
One of my professors gave up and spent several thousand dollars on a new computer with a huge solid-state drive because he could not get an emulator window up in less than five minutes, and it was impacting his ability to teach courses based on the platform. I went the cheaper route and dropped $200 on a tablet. Either way, hardware is the real answer here.
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.
Regards
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 just created a android AVD which runs on the 3.1 version. After it starts running, it takes a lot of time to move from one activity to another. Is there any way I could speed up this process.
Emulators will always run much slower than the devices. Anyhow, the android emulators now are much faster than before, so make sure you keep your sdk updated (and you obviously have, since you're running 3.1).
Also, I consistently noticed that emulators running in ubuntu 11 are faster than the same emulators in Win 7 (same hardware), so you might want to give ubuntu a try.
Android emulator takes a lot of memory while it's starting up. It's normal. The thing you can do here is using a feature called snapshot. Snapshot will save your time (and probably resources) from the start booting up.
Read this article for more details:
Optimizing Apps for Android 3.0
under the "About Emulator Performance" section.
Hope it helps.
On my system, i am using eclipse ganymede version along the Android SDK and ADT plugin installed. I have created an android AVD (target android 1.5) with 512MB of memory. Its quite frustrating to see the slow boot up of it. It takes around 4-5 mins to complete its boot-up. Is there any way or tweak to speed up this boot up process.
PC config:
P4 2.4 Ghz with 1 GB ram.
You can use the -no-boot-anim command line option which speeds up the boot process by not showing the boot animation while the emulator starts up. It makes an noticeable difference on my system reducing start up time from around 55 seconds to nearer 45 seconds. (In case you're interested this is on a laptop with a Mobile Core 2 Duo L9400 and 3GB of RAM.)
Use a command line like this to start the emulator:
emulator -no-boot-anim #YourAvdName
where YourAvdName is the name of the Android Virtual Device (AVD) image that you want to start.
There is now way of to speed up the boot process. This is the downside of having a real emulator not just a simulator like the Iphone kit offers.
You don't have to quit the emulator after a test run. Just start the emulator at the beginning of your work and close it after you are finished. If you want to test something very quick I often find it easier to just connect my actual device and run my app on the real device, without waiting for the emulator to start up.
There's no real way to cut the time down significantly, and it performs so poorly as a tablet device, it's barely usable. Bottom line, you need a real device to produce production apps. It's good for learning though.
The "emulator" is widely known for being a simulator. It does not:
come with device roms or known emulation for real world devices
off phone or SMS support
have the ability to open listening sockets for incoming requests
etc etc. It is not an emulator like mame. It's a simulator like the iPhone/iPad simulator.
i started off with the default settings on the AVD manager to create a new AVD and it started up kind of ok, about 1-2 mins. later i deleted that and created a new AVD with 8GB internal memory (like the real device i'm using) and startup didn't! i waited 30 mins but still nothing
so i reverted to the default memory (512MB) and it seems to start ok
but i also noticed, its a bad idea to unclick the hardware buttons options, that causes it to load slow too
install virtualbox and use androVM
much better than the emulator
The option that I select so far is to buy a cheap mobile from Kogan.com and use this is your app tester.
Otherwise you can also go and install Genymotion, which is definitely a ++ tool over AVD through Android Studio.
It is fast as well. However, keep in mind that there are many features that will be missing such as google play services. Thus, it is advisable that you buy a device. With Android supported mobile, you could basically do everything and simulate every events such as swipe shake etc...
