Android Virtual Device Manager - Webcam0 on 4.4.2 not working

I've configured a virtual 4.4.2 (arm) Android Device in the AVD (Full Settings below) and need to use my webcam to test the camera.
The camera app starts and crashes instantly (Camera has stopped working).
I get the following log output:

Use Genymotion for testing app it work like AVD and you can use Camera in Genymotion.
You can check on Link About Genymotion and features of Genymotion.

we are porting whole android open source for the device Imx-6X-solo board.Developing and re-skinning all the applications.Every thing is done properly and device is ready now.

I got the solution. By mistake I removed the Contacts app. Every time, Contacts Storage app is checking for contacts.So Now again I installed Contacts.apk. And it works fine after installing.
one more solution is
Settings --> apps --> All --> Contacts Storage --> clear data and Force stop

Backup your contacts. Go to settings and clear the "Data" of Contact Storage. This will remove all your contacts. After that, restore your contacts back and the error will go. This basically happens when FB messes up with your contacts.

it is not directly contacts related. 10 minutes ago this message start to popup every 1 second (!). It started to popup after i removed my account from DROPBOX. I tried rebooting several times but nothing helped.
Finally i decided to re-link the account i removed from DROPBOX and then the popup message stopped !
The problem appears because there is a broken link. To some it appears with contacts. To me it happend with DROPBOX. I assume to others it can happend with a different app.
It is an Android failure, not an app faluire.
(I use Galaxy S4 with Kitkat 4.4.2)
Good Luck,
Yuval

My repair has not been posted as of yet - here is another.
Settings->applications manager->bottom left menu button / Choose reset app preferences / Choose Reset Apps.
This worked for me ,,, Must have shut something off that android/Samsung didn't like
cheers

Why debug window is empty in Eclipse running an Android app?

Why is the debug window empty debugging an Android app that does not include a MAIN and LAUNCH activity, but only a receiver? Is it normal or there is something wrong?
When I launch the app in debug mode this is the LogCat:

As you can see the application was already installed on the emulator, but the same issue is present when the application is installed for the first time.
Let me know whether it is useful to see also the code.
I tried with a slightly different version of the same app just to force Eclipse to reinstall the app in the emulator (added a space). This is the LogCat of the reinstallation:

Just recreate or edit your emulator and be sure that under the hardware list you have
GPU Emulation set to Yes

I searched a lot on google and stackoverflow, but unable to resolve the error.
I did not change single character in the starter code then why its not running.
When I try through emulator (as described in tutorials) it gives PHONE_REGISTRATION_ERROR.
Used software:
Eclipse Java EE IDE for Web Developers.
eclipse platform 3.7.2
Version: Indigo Service Release 2
Build id: 20120216-1857
ADT 18.0.0
app engine java sdk1.6.6
gwt sdk 2.4.0
This is the debug stack:
DalvikVM[localhost:8600]
Thread [<1> main] (Running)
Thread [<8> Binder Thread #2] (Running)
Thread [<7> Binder Thread #1] (Running)
Thread [<9> IntentService[my_registered_c2dm_id#gmail.com]] (Suspended (exception RuntimeException))
C2DMReceiver(C2DMBaseReceiver).onHandleIntent(Intent) line: 124
IntentService$ServiceHandler.handleMessage(Message) line: 59
IntentService$ServiceHandler(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 130
HandlerThread.run() line: 60
On clicking thread 9 variables it shows this:
com.testtasker.C2DMReceiver#4052c3e8
Intent { act=com.google.android.c2dm.intent.REGISTRATION cat=[com.testtasker]
cmp=com.testtasker/.C2DMReceiver (has extras) }
Please help me, I have to work app engine but before that this sample should run on real device.

I don't know which "tutorial" you are using. With the ADT 18 you won't be able to run the one here http://bradabrams.com/2011/05/google-io-session-overview-android-app-engine-a-developers-dream-combination/
Instead follow the instruction here:
https://developers.google.com/eclipse/docs/appeng_android_install_setup
Also, make sure to register for the c2dm service: https://developers.google.com/android/c2dm/signup, which I think is your actual problem. I believe when testing you must sign in with the same account you used in registration on your phone and the local App Engine server.
Have you customized files, or are you trying to test the c2dm service out of the box?
