Closed jpabanil closed 6 years ago

Hi,

I was trying to use your library in our project but got this error when I open the MainActivity that holds the fragment. I hope you can help me as soon as possible.

java.lang.NullPointerException: Attempt to invoke virtual method 'void com.google.android.gms.samples.vision.barcodereader.BarcodeCapture.setRetrieval(xyz.belvi.mobilevisionbarcodescanner.BarcodeRetriever)' on a null object reference at ca.easyreg.easyexhibitor.fragments.BarcodeScanner.onCreateView(BarcodeScanner.java:108)

Thanks in Advance!

J
