I've started developing for Android.
I want to write an barcode scanning app, but without a way to activate the camera in the emulator it could be annoying.
Does anybody knows a way to use the USB-Webcam of my PC as an Android Camera ?
I've searched everywhere i know there is a lib from tomgibara, but it would be really nice if some has got an sample project for this.
At the moment the Emulator only asks for the capturing device, but when i start now the camera app from android i only see this dummy camera site with this chessy squares.
Thank you for all of your help.
You can specify which camera to use and how in the emulator command line using the options
-fake-camera <mode> set fake camera emulation mode
where mode can be one of back, front, or off, and
-webcam name=<name>[,dir=<direction>] setup web camera emulation
where name is a valid connected camera name and dir is one of front or back.
The connected camera names can be obtained by using the special option -webcam list.
For example, in Linux you can obtain something like
List of web cameras connected to the computer:
Camera 'webcam0' is connected to device '/dev/video0' on channel 0 using pixel format 'YUYV'
OK after some tries I am able to run the emulator on the way you described above, but the fake-camera option does not help =(
It let me choose which camera I want use and after i clicked "OK" the emulator starts, but without the webcam as front or back camera =(
Is it possible that it is a webcam which is not supported ?
If Yes: which cameras are supported ?

I'm trying to get an emulated virtual device to use my laptop's webcam to simulate the device's camera. Based on my research, it should simply be a matter of enabling camera support and setting the back camera to "webcam()" which I have done, but it is not working. When I run my app that initiates the back camera, I notice a line in the output window: "Could not find requested camera." Here is the configuration for my virtual device:
The app runs fine otherwise, I just can't get the camera to work. Note that it works on an actual device so the issue isn't with the app. My laptop's webcam works fine in other programs and I have ensured its drivers have been updated. Why can't it find the webcam?
I am trying to use my laptop webcam as my back camera of my emulator for sdk version 10 and 16, but in both case the emulator does not found my webcam though the emulator does not show any shortage of SD cart memory or also request permission for using webcam. When I run emulator's default camera app, it shows grid of gray and black with a greed rectangle moving here and there, when capturing photos it capture the same thing at that time on screen. Can anyone give me any solution please. My complete emulator configuration is:

Short story is:
Go to AVD manager
Select your device
Go to device properties
Change back facing camera dropdown value to "webcam0"
If it all not working you can try to use genymotion emulator http://www.genymotion.com/
It works much more faster and it easy to use your laptop webcam as back camera of the device
I use android SDK 4.0.3 and eclipse Indigo and I'm trying to develop an application which uses a camera. When I take a photo, this message appears:
Unfortunately, camera has stopped.
In the eclipse console:
emulator: ERROR: _camera_client_query_frame: Unable to obtain first video frame from the camera '/dev/video0' in 2009 milliseconds: Resource temporarily unavailable.
My OS is Debian Squeeze. What can I do? Thanks.
In emulator camera does not work properly .You must try it on Real Device.
As Shahzad imam said, you can't use camera on emulator.
But if can't buy real device and you're really need camera you can try to translate video to network from your PC and then handle it in Android, as it a real camera. Or, if you just need photo, you can use some picture instead.
Can I use my webcam connected to the AVD for testing camera and its functionality?
I have read in some articles that Android 3.0 + supports this feature.Is it possible?
I also receive a connect cam dialog box when my webcam is connected, when I start my AVD.
Using Eclipse.
AVD Manager
Edit the AVD.
Hardware > New:
Configures camera facing backwards = "webcam0" (use dropdown).
Run project using that AVD.
Its some tricky way either its work or not I don't know...
But you can try it, Look at How to use web camera in android emulator to capture a live image?

i'm developing an android app that needs to capture a camera picture,
is there any way to configure my AVD to use my conputer webcam on the emulator?
when i open the default camera app it shows me an squareanymation, can i use/configure the emulator/avd to use my computer webcam?
I really can't think of a way to do this.
I would do the following:
During development, when debugging on an actual Device under adb, use the camera as normal. While debugging on an AVD, comment out your camera code and us a pre-taken a png to your app that resembles/emulates the photo the camera would have taken. This would let you work on the picture analysis regardless of the camera, and finish your app without an actual ADB device, just AVDs. One you get ahold of a real device you can finish up.
On another note, if you are ready to go poking around in VMs, Android Kernels, and HALS, you could follow this article (http://bytecruft.blogspot.com/2011/05/alternative-to-android-emulator-and.html) which tells you how to setup Android X86 under VMWare or Virtualbox as an ADB Device. I'm sure setting up the host machine's webcam as a camera would be much easier that bay (VMWare device bridging comes pretty close).
Hope I helped.
