Android How to use webcam in emulator

Question

I m connecting a webcam to my emulator by setting the front camera to  webcam0  in the AVD Manager   When I start the emulator s camera application  I get the error  CameraService  connect X  pid 702  rejected  invalid cameraId 0     Here s the relevant portion of the Android source code   sp lt ICamera gt  CameraService  connect      const sp lt ICameraClient gt  amp  cameraClient  int cameraId         int callingPid   getCallingPid                    if  cameraId  lt  0    cameraId  gt   mNumberOfCameras            LOGE  CameraService  connect X  pid  d  rejected  invalid cameraId  d                 callingPid  cameraId           return NULL                       The webcam has been correctly assigned an ID of 0 because there s only 1 camera  However  mNumberOfCameras is presumably still 0   This means that the camera is being registered by the emulator  but it hasn t bothered to update the number of connected cameras     How can I connect a webcam so that it will be properly recognized by the emulator   Edit  the command emulator -webcam-list -avd  lt name of your AVD gt  in  android-sdks tools gives the result   List of web cameras connected to the computer  Camera  webcam0  is connected to device  AndroidEmulatorVC0  on channel 0 using pixel format  BGR4    When I launch the webcam from Eclipse s AVD manager or using emulator -camera-front webcam0 -avd  lt name of your AVD gt   I get the following window      Edit 2  This seems to be a bug in the emulator  The suggested answer tells you what to do to set up the camera  but doesn t solve the problem for me   I ultimately solved it by using a laptop with a built-in webcam   Perhaps another USB webcam might have worked as well
