Question

I don t have an embedded camera in the lid of my notebook. I d be hooking up through an external USB camera.

The emulator runtime can pick this up right? I ll get the image displayed inside the AVD skin s screen in real time?

Answer 1

Afaik the emulator wont show a realtime camera regardless.

If you need a live camera-source to use in your own app for debugging, there is a sollution at http://www.tomgibara.com/android/camera-source

Answer 2

In the current release of the emulator (Ice Cream Sandwich, API14;Linux), web camera support is available. Google s documentation and most answers available on the web do not yet reflect this. The emulator itself does:

emulator -help
...
-fake-camera <mode>      set fake camera emulation mode
-webcam name=<name>[,dir=&lt;direction&gt;] setup web camera emulation
...
emulator -help-all

and further:

help for option -fake_camera

Use -fake-camera <mode> to control fake camera emulation. Valid values for <mode> are:

off   -> disable fake camera emulation
back  -> fake camera is facing back
front -> fake camera is facing front

help for option -webcam

-webcam off to disable web camera emulation.
-webcam list to list web cameras available for emulation.
-webcam name=[,dir=<direction>] to setup parameters for web camera emulation.
- <name> platform-independent name identifying emulated camera device.
- <direction> defines direction the camera is facing. Valid values are:
  - front -> emulate camera as facing front
  - back -> emulate camera as facing back
    
    Default direction value for emulated web camera is front

Answer 3

Time to upgrade your ADK!

As of Android SDK version 14, the emulator supports webcams to simulate a camera:

General notes - Added webcam support to Android 4.0 or later platforms to emulate rear-facing cameras when one webcam is present, and to emulate both rear-facing and front-facing cameras when two webcams are present. Webcam suport is for Windows and Linux only. Mac support will come in a later release.

from: Android SDK Tools, SDK Tools, Revision 14

It works! I ve tried this myself.

Answer 4

From the android documentation:

Emulator Limitations

In this release, the limitations of the emulator include:

...

No support for camera/video capture

...

In other words, no, you cannot access or preview the camera in the emulator.
