I'm getting started with Android development, but the emulator performance on my machine leaves much to be desired. In all fairness, my machine is not a powerhouse by any stretch of the imagination.
Short of upgrading my hardware or spending $$$, are there any good tips for improving Android emulator performance?
Is testing on your own phone an option? That is a million times faster.
Also, are you "debugging" or "running" your app? If you don't need to step through code, consider running it rather than debugging it.
If you haven't added 2.2 to your toolbox, that will help. Once it's started, emulated 2.2 runs a bunch faster than emulated 2.1.
I still go back and test my applications on the older OSes, but for day-to-day development 2.2 has helped a lot.

So far I have been developing directly on my galaxy nexus and nexus 7 using the amazing AID app.
However, as the N7 can't provide logs due to it being jelly bean, i feel the need to get a mini notebook in order to utilise adb logcat.
My main worry is that something with only 1gb (2gb if i upgrade, which i will) and a 1.5-1.83GHz atom CPU won't be powerful enough.
I can possibly get around certain worries by not using emulators and testing directly on my two devices, so that will save me a great deal. Also I am tempted to just use vim and command line tools instead of eclipse which again might save me from a slow PC.
What do you guys think? Is the notebook way under powered? What if i just use vim and no emulators?
Side note, does anyone actually code in vim/command line?
something with only 1gb (2gb if i upgrade, which i will) and a 1.5-1.83GHz atom CPU
will work just fine, as long as you're not planning to run a tablet emulator. I sometimes have to work at my Asus EEEPC with the same exact CPU and I've got no problems so far
It is doable with 1gb RAM and using vim/commandline tools. However, eclipse provides a project wide perspective which is hard to duplicate in vim (vim power users may be as productive, if not more though). So in terms of memory 1, 2gb RAM will be fine. Testing on devices is always better than emulators.
One thing else though, a commandline build with multiple module dependency is non-trivial to setup and maintain. This is because Google has historically been modifying the build.xml file, breaking existing build scripts fairly regularly. So if you are well versed with build script internals and prepared to work on them you should be ok.
Debugging Android apps without Eclipse based breakpoint debugging support may be a significant issue too. Some bugs are caught in a lot lesser time with this. So plan accordingly if you don't want to use Eclipse.
Eclipse also provides very good JUnit/Robotium support for writing test cases, You won't get this with vim.
As I wrote down these points I think running Eclipse in 2gb notebook should be possible (just don't run other apps with doing development) and thus is recommended.
I have extensively used vim just not for Android development. You can also install vim plugin for eclipse if you prefer that.
Modern notebook hardware certainly is capable for software development; in fact, many (hobbyists as well as professionals) use a notebook as their main development platform.
However, with a mini / ultra-small form factor, you'll pay more for a less capable machine. Unless you need extreme mobility, I would suggest a standard notebook, with a little extra money spent on RAM (8+ GB) and an SSD. (Then, neither big IDEs nor emulation is out of scope.) If money is an issue, you can still get clunky-looking, but fairly powerful 15" or 17" laptops.
i think you Configuration is good enought to run Eclipse , Myself i had to Remove some Composant on my PC beacause we have 1 PC for Work/Internet/Eclipse and 1 PC for Gaming Etc ... , iam using Galaxy S2 and dont use Emulator many times , Yes i have some Slow Down some Time , but try Eclipse with the Minimal Configuration and No Emulators but Upgrade to 2 GB i have myself 2 GB Here and DUal Core E5200
Yeah that's under powered. For a windows PC I'd want 4gb of ram, not sure about Linux but atoms are dog slow either way.
I'm sure it'll work but it won't be fun, I'd be most worried about disk speed as that's what drives me nuts most.
I'd also take advantage of the ide and all its nice features too
I'm developing an android application, since there are many assets, the generated apk is near 10M. Now deploying it to a simulator is very slow, often takes me 3 or 4 minutes, which is unacceptable.
I've used Robolectric to test most of the logic, which is very fast. But sometimes I still need to use emulator(e.g. adjust the UI), which waste me a lot of time.
Is there any way to make it fast?
This is my experience, too. Debugging with the software emulator is very slow.
It is much faster to use a real device in debug mode. However, you may run in other limitations
Well since somebody suggested Android x86 as an alterante testing Emulator, I'll also present my favorite. This might not be an alternative for everyone but for me it's perfect! Use the Bluestacks Player. It runs Android 2.3.4 and is very fluent and fast. Sometimes even faster than a normal device. The only downsize is, that you can just test Apps on the API Level 10 and just on one screen size, but it's perfect just for testing if it's working or not. Just connect the Player with the adb by running
adb connect 127.0.0.1
After compiling it installs instantly. Very impressive, considering I have a rather average computer hardware(dual core with 4 GB of RAM)
I've found android-x86 image on VirtualBox many times faster for deployment than an emulator running on same machine, sometimes even faster than a USB device.
EDIT
Please use the android image provided by vmlite, not the one provided by android-x86, and refer to this important question: How to change the screen size of vmlite android?
Actually, I absolutly never use the Emulator, which is way too slow in every situations.
I test and debug my apps directly on real devices (and use the ADB screenshot features when I have to pixel-check some screens..)
Hope this helps...
Is there a way to make the emulator work correctly ? it is extremly slow and there is really no way to debug application this way.
Anyone experiencing this ?
Note : This is for the android 3.x platform of the SDK.
Thanks.
Everyone is experiencing this issue, even who have Intel i7 with 16 gb of ram...
The problem is that the biggest resolution (mostly 1280x800) have killed the emulator performance...
At the last google I/O some kind of hardware acceleration was shown, but it's in early stage of development I think.. But the performance were way better.
Today the only solution to develop on Honeycomb is to buy a real tablet..
The Android Emulator is slow with every OS version (but Google is working on it). Also, if you're running the Emulator on an already slow system, this slows it down, too.
If you're getting any errors, feel free to post the outputted error-messages. Otherwise I'm afraid you'll have to wait until the performance-issues are solved.
What is the best platform and setup for running Android SDK? It is so slow that I cannot stay focused on it.
If I had any hardware resources at my disposal and cost wasn't an issue, what should I do?
Also, is there some sort of cloud SDK host that can provide a faster experience. (Security isn't a concern. Just need to debug web sites.)
I have really bad experiences with running on Mac software so, aside from special cases, I would avoid mac hardware (yes I know they are seperate things, but still).
In my experience a VMWare virutal unbuntu in OSX runs Eclipse/javaSDK faster then just directly in OSX, on the same machine.
I had a very similar problem, my development machine is old and slow and Eclipse was killing it. I recently switched to IntelliJ Idea and it is much faster. I suggest at least giving it a shot. It has really good support built in for the Android SDK including logcat.
I would like to start doing some Android development, and would like a cheap device to deploy apps to, just for testing and demo purposes. Is it possible to deploy apps to, for instance, an Archos 28? I don't know much about Android development yet, and haven't found a good answer to this question elsewhere. Thanks.
I can recommend the A28 for development. The user experience is rather crashy, part of the problem lies in the low RAM (128Mb is very little for an Android device). But I developed JGame on an A28 and did not run into firmware bugs. It also runs Flash 10.x in case you want to experiment with that.
I second that you should in particular worried about devices with a larger display. I found that graphical performance can be much worse on those devices. The A28 has a pretty good GPU considering it has several times fewer pixels than the average Android device.
Yes, it is running android 2.2 froyo. That should work fine for development purposes. Just keep in mind that some people will be using your app on cell phones that may be "larger" than the archos' screen size.
