Using FastBarcodeScanner even with your demo application throws java.lang.NullPointerException: Attempt to invoke virtual method 'void android.graphics.Bitmap.copyPixelsToBuffer(java.nio.Buffer)' on a null object reference when using LegacyScanner on LG G4s Android 5.1 with Legacy support for Camera2 API.

In LuminanceSourceFactory.java line 96, BitmapFactory.decodeByteArray(data, 0, data.length); returns null, in BitmapFactory.java line 634 nativeDecodeByteArray(data, offset, length, opts); returns null which causes bm.copyPixelsToBuffer(pixelBuffer); to throw. Most likely the jpeg data passed to it is corrupted, at least in my case it was when I checked the array, it was normal until some point where it was filled with -128 and 127 0, 0, 1, 0, -128, 127, -128,
