android emulator in ADT plugin not running

问题:

I'm using Eclipse ADT plugin for android development. I came across some problems and I remove all my existing emulators and create a new one. when I run an android project and start the emulator, it just pop up and freezes with a black screen even before it start Android os.

and the progress tab shows,No operations to display at this time. and the logcat displaying I/ServiceManager(270): Waiting for service SurfaceFlinger... over and over again. And the console shows

[2013-12-02 14:54:03 - Emulator] emulator: warning: opening audio input failed
[2013-12-02 14:54:03 - Emulator] 
[2013-12-02 14:54:04 - AndroidV4Virtusel] New emulator found: emulator-5554
[2013-12-02 14:54:04 - AndroidV4Virtusel] Waiting for HOME ('android.process.acore') to be launched...

But the emulator never launched. No rusalt although I restart the IDE.

when I restart the adb using DDMS perspective it gives following error.

[2013-12-02 15:22:50 - DeviceMonitor] Adb connection Error:An existing connection was forcibly closed by the remote host
[2013-12-02 15:22:51 - DeviceMonitor] Connection attempts: 1

The avd manager also shows the emulator as a valid emulator

And when I close the emulator the console shows,

[2013-12-02 15:34:23 - hierarchyviewer]Unable to get view server version from device emulator-5554
[2013-12-02 15:34:23 - hierarchyviewer]Unable to get view server protocol version from device emulator-5554
[2013-12-02 15:34:23 - ViewServerDevice]Unable to debug device: My1 [emulator-5554]

[2013-12-02 15:34:23 - hierarchyviewer]Unable to get the focused window from device emulator-5554 

So can someone help me? Thank you!!!

To solve this, go to Window --> Open Perspective --> DDMS. In the DDMS View, look for devices on the left of your screen. You should see a bar having about 12 icons. Click on the down arrow and click the "reset ADB". It should work afterwards.

In this case, I was able to run an emulator with Android 2.2. But unable to run an emulator in Android 4.2 which is my applications target. So i just removed Android 4.2 (API 17) and just reinstall it. Later on emulator starts fine. Thanks!!

I would suggest you to use the blue stacks as your emulator.. its really faster and efficient.. If you are using the Blue Stacks, first start your blue stacks and then eclipse or whatever the IDE you are using...

As an extension to Jimi's answer, the easiest way to restart adb is to type the following command into a console window:

adb kill-server

If you get an error about adb command not found, then you can either add the android system tools path to your PATH key in environment variables, or just navigate to the tools directory and execute the command from there:

./AndroidSdk/platform-tools

After killing the server, make sure it's restarted correctly by typing:

adb devices

Which should show you a list of connected devices.

After restarting adb, the device manager should automatically refresh, otherwise try restarting device manager or selecting the refresh window button.

Maybe there is something wrong with your AVD properties,change it to where it compatible to your android projects,that's all.
