msp = new LocalCameraStreamParameters(true, true);

msp.setCameraId(2);//0\1\2\3  is'nt  work.

another method isn't work yet:

LocalCameraStreamParameters.CameraType ca=LocalCameraStreamParameters.CameraType.valueOf("/dev/video2");
msp.setCamera(ca);

Please check if it's in LocalCameraStreamParameters.getCameraList(), which means can be recognized by Android.

setCamera() will only accept one of the types in the list returned from above method.

[Lei_Z_Intel1]

If the USB camera is the only camera of this Android device, it should be in the the getCameraList().

[allen_w_]

getCameraList() cannot find any camera

QQ can find that camera and use it .

Has any other method to get it?

Generally we don't support to get all external USB cameras in Android SDK. We are considering to add this capability in next release.
