Scan until EAN found?

[gtzippy]

I'm using this for a little home project with my kid's books. It is great, and easy for a young child to use, but sometimes the scanner stops and returns the barcode before it finds the EAN suffix. Is there a way to say "do not stop scanning a barcode until you find an ean5 or ean2 suffix"?

It's currently not possible via the default method of using ScanContract & CaptureActivity. But if you use a custom Activity, you can replace the DecoderFactory using this:

zxing-android-embedded/zxing-android-embedded/src/com/journeyapps/barcodescanner/BarcodeView.java

Line 103 in d09b7c7

public void setDecoderFactory(DecoderFactory decoderFactory) {

Then you can set this hint on the decoder:

Another option is to use the continuous scanning example as a starting point, and only stop scanning if you find a barcode with the suffix.
