How to use web camera in android emulator to capture a live image?

As far as i know, Android emulator doesn't have a camera. To capture a live image we have to use the web camera. I have seen code in this web site to use the web camera in the android emulator to capture an image, but I don't know how to use this code.

1. Download all the source files listed on the page: CameraSource, GenuineCamera, HttpCamera, SocketCamera, BitmapCamera, and WebcamBroadcaster.
2. Create a package in your project called com.tomgibara.android.camera and place the first 4 source files inside.
3. Download JMF from here and install it.
4. Compile WebcamBroadcaster using the following command: "C:\Program Files (x86)\Java\jdk1.6.0_15\bin\javac.exe" -classpath "C:\Program Files (x86)\JMF2.1.1e\lib" WebcamBroadcaster.java or what's equivalent to it.
5. Run it with the following command and keep it running: java "-Djava.library.path=C:\Program Files (x86)\JMF2.1.1d\lib" WebcamBroadcaster
6. Use the following code in your program:

CameraSource cs = new SocketCamera("192.168.0.100", 9889, 320, 240, true);
if (!cs.open()) { 
/* deal with failure to obtain camera */ 
} 
while(/*some condition*/) {   
cs.capture(canvas) //capture the frame onto the canvas
}
cs.close();

PS: I haven't been able to test this because I'm getting an error when I run WebcamBroadcaster.

PPS: I just started experimenting with Android today so all this could be wrong.
