Barcode.EAN_13 not recognized

[tobrun]

While trying out the sample code:

• QR-scanning
• Face recognition
  works as expected.

When I try to scan an EAN_13 barcode:

• BarcodeTrackerFactory.create is never called

Also I tried to configure a specific barcode variant, but this resulted in same behaviour:

• new BarcodeDetector.Builder(context).setBarcodeFormats(Barcode.EAN_13).build();

This may be a camera focus issue -- some of the barcode formats work better when the camera is fully in focus.

Is your app using CameraSource? As discussed in another thread, this initial release does not have an auto camera focus option on CameraSource, but this will be added in a future release. In the meantime, you might try the workaround suggested by Aeefire in this thread:

I don't see the EAN_13 barcode as supported. Maybe that's why? Is it intended?

For 1D Bar Codes, these are:
AN-13
EAN-8
UPC-A
UPC-E
Code-39
Code-93
Code-128
ITF
Codabar

Update1: I tried myself and EAN_13 works, but yeah sometimes (specially when it's too close) because of the focus issue it's hard to read.
Update2: Nvm it's listed here as supported: https://developers.google.com/vision/barcodes-overview

We have recently open sourced the CameraSource class:

https://github.com/googlesamples/android-vision/blob/master/visionSamples/barcode-reader/app/src/main/java/com/google/android/gms/samples/vision/barcodereader/ui/camera/CameraSource.java

This version includes an auto-focus option, which will probably help.

If you are using CameraSource, you'd enable focus mode by calling this builder method:
