I install the StateManager library first and that was find but it look for something in Reflection lib. I installed it but it keeps telling me unable to find "Reflection.Bas".
You should download and copy the library: Libraries - Basic4android Wiki to the libraries folder.
You should then check it in the Libs tab (first right click and press Refresh).
I tried to add the reflection and barcode libs and each time it states that it loads fine but what I missed is that it stated next unable to find .bas at C:\Users\Ron Arnold\Documents\B4A Projects\Files\Files\Reflection.bas and also for the C:\.......\OnBarcode.AndroidBarcode.bas
