lately I am facing some troubles with my android emulators, some of them start but never work, others start and after several minutes my pc crashes and others do not start at all.
Any solutions? Like turn it off and on? or just restart your computer when something bad happen?
I will appreciate any help!
If your RAM is below 8GB then you want to consider upgrading your
RAM.
Run one emulator at a time. Sometimes you might get frustrated and
therefore starting up two at a time, this will slow down your system
and the emulator performance as well. Solution for this is run a
system task manager check to see all running process then terminate
the unnecessary processes running.
Finally, if the above don't help; I will suggest you download
Bluestack Android Emulator as that is so much kin to work with and
reliable.

As per the title, my Android Studio seems to be using too much memory, even at idle. For my friend, he is able to run his emulator at only ~300MB of RAM usage, according to Windows' Task Manager. I've tried duplicating his emulator settings, even with his emulator set to 1.5GB of RAM, it is only using about 300MB. Mine goes up to 1.5GB, sometimes even 2GB, just by getting it started, I'm not even running any apps on it.
Is this even possible? Running it at only ~300MB, because on mine, the lowest I can go is 1024MB, setting anything lower results in no change in Task Manager.
Maybe in the installation process you installed more things than him. That's why it's eating a lot more memory
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.
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.)
Sometimes the emulator will start and it will say No Service and the internet connections will stop working. Then I restart the emulator once (or twice sometimes) and the next time it works.
How can I stop this from happening?
I don't think there is a sollution, I certainly don't see how the answr #selladurai links to will help here.
This does happen to me once in a while too, on various systems (It has happened on Windows and Ubuntu, I think also on Mac, but I'm not sure). The only "sollution" seems to be what you are suggesting yourself: restart the emulator. This just seems to be one of the instabilities of the emulator.
I went through the simple hello world application on the android developers forums to an absolute T. But, when I start the emulator all it comes up with is a large black screen that just says ANDROID_. The '_' is flashing. Does anyone know what may have caused this or why it is not working.
It can take a while to start. Remember it is emulating an ARM processor so that can take a while depending on the specs of your machine. Start it and give it 5 min. If it hasn't come up by then you may want to close and restart. While it is starting up, if you open ddms you can follow what is going on in logcat.
Good news is that if you enable snapshots, once you get it started and saved (it does this on its own). Subsequent starts should be pretty quick.
For some reasons, the android emulator does not work properly on any of the laptop's i have. It lags even on my high end laptop with 4 gb Ram, i5 processor and 1 gig graphics processor, so i connect my phone using usb cable, enable debugging mode and run the app on the phone from eclipse. You will need a working adb connection as stated on android developer website though. It works pretty good and is way better than using an emulator. :)
It takes about 3 mins for the emulator to load on a laptop. Wait for about 5-6 mins if not. close it.
In case when you restart still you get the same, go to AVD Manager delete the image and create a new one.
As the others have said, the emulator is very, very slow to start up. It can get wedged on startup for me, every now and again, but shutting it down and trying a second time almost always works. And yes, you can leave it running the whole time, but note that Eclipse and/or ADB can get wedged as well. You'll see logcat stop updating inside of Eclipse. I can usually get it restarted by doing
adb kill-server
adb start-server
Sometimes, just doing an adb logcat on a command line will get things moving again. Good luck.
