I copied the zxing jar file into lib folder of my android app and build the path,but for some reason I have to use some of the zxing classes into my own package(not the com.google.zxing package). If I tried to put those classes, I used to get the error. But when I import the zxing packages outside my package, I have to change the R.ids of all the zxing classes into my-package.R.id.
So is there any way that I can use zxing classes in my own package?
