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.

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.

The emulator won't launch my apps even on a real device! I've tried every solution online, even reinstalling android sdk,ADT plugin. The app run SOMTIMES(4x to be exact) though, like awhile ago, when i got home i tried it again, and it run on my first try then i began working on the code again then i tried to run it, won't run again. Even basic apps like hello world won't run most of the time. I've set the run configuration to let me choose my device everytime, but even the device chooser wont show up(showed up once only), i tried waiting for 30 minutes(also tried the kill-server start-server) but it just wont run! my real device, or the emulator is listed on the DDMS perspective and there's nothing on console. please help, cause I've wasted 2 days for this already.
Have you also tried, taking the USB cable then disabling debugging and then enabling debugging and putting the USB cable back.
I remember this happen to me, so I did what I mentioned and surprisingly it works. Hope it work for you too.
Maybe you should try deleting your emulator and creating a new one. Make sure that all your settings are correct and that you are targeting the right OS version.
I've had quite a few problems with the emulator and wiping them and starting from scratch worked more often than not.
As for the real device, the first real hurdle is getting the right drivers so that your PC can recognize it, after that kill-server start-server usually does it. I'm surprise that didn't work for you.
I've done everything to the 'T' in regards to installing the Android SDK/ADT. I've tried all methods to resolve this (adb kill, wipe data), but still nothing.
When I run it from the SDK manager, the loading process works, but once it is done, a flash of the emulator appears then quickly disappears.
Sometimes after it loads, nothing happens.
At the worst when it loads, I get the "too many emulator instances are running on this machine. Aborting" message.
I want to start making apps, but this seems to be the only thing stopping me!
Eclipse Indigo; r12, Windows 7 (64)
If you have Windows Firewall (or another software firewall) active, try temporarily turning it off and then running the emulator. If that clears up the problem, then you need to teach the firewall how to open up the ports the emulator needs.
Go through your services and kill anything you find from it, including the java runtime, then run the AVD Manager as Admin and start the emulator from there, that should fix it.
I try to always make a habit of running Eclipse as Admin too because it's needed for the Emu to run properly.
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.
I have a problem with the Android emulator. After I run my application on a device it disappear from DDMS at some moment with no reason, even if it is still started. The only way to run again is to close the previous emulator and reopen it by running my application.
Do you have any solution for this strange error ? I must say that I can't deactivate my firewall if that is the problem. Also I tried to reset ADB but still doesn't work.
An answer for others that will come here looking for a solution.
You just need to restart ADB (kill-server and then start-server).
