Runtime error …\documents\corona projects\EndofEarth\main.lua:52: attempt to index local ‘bg’ (a nil value)
This is the error that apears when I open the apk on Android device. In the simulator it works fine but when I build the apk and install it on the Android device, it gets me the error.
Any help?
