Re: Trying to implemate zxing - crazy error in CaptureActivity

Looks like you have a portrait-mode layout but are not setting the camera orientation properly. It's really up to you.. the app is landscape only.

Hey Sean Owen, thanks for your quick answer. Is there any posibility to use it in a portrait-mode? Is it as simple as i have just to implement a capute.xml layout file on my own?

It's not nearly as simple as a portrait layout, no. You will have as much fun as I did in creating Barcode Scanner+, and dealing with all combinations of orientations, front/rear cameras, and device bugs, if you want this to work!

Try this to see a working example: https://play.google.com/store/apps/details?id=com.srowen.bs.android

Most of the battle is knowing how to correctly detect the camera's orientation relative to the device's native orientation, and the device's current orientation. It boggled my mind for days, but maybe you are smarter. But yes you must call methods to set the orientation correctly or you get stuff like this.
