How to make the ZXing scan using the front camera not the back camera in Android?

问题

I am using the ZXing by the following code ContinuousCaptureActivity, and the zxing using (by default) the back camera to scan, how to make it scan using the front camera ?

回答1:

set extra SCAN_CAMERA_ID to the ID of the camera you want

usually 1 for the front one.

for example

 intent.putExtra("SCAN_CAMERA_ID", 1);
