Can not use Google Barcode scanner

Question

I tried Google barcode-reader from https://github.com/googlesamples/android-vision

This example doesn't work. When I tab to screen it always detect

"no barcode detected"

Debug reason :

private boolean onTap(float rawX, float rawY) {

    //TODO: use the tap position to select the barcode.
    BarcodeGraphic graphic = mGraphicOverlay.getFirstGraphic();
    Barcode barcode = null;
    if (graphic != null) {
        barcode = graphic.getBarcode();
        if (barcode != null) {
            Intent data = new Intent();
            data.putExtra(BarcodeObject, barcode);
            setResult(CommonStatusCodes.SUCCESS, data);
            finish();
        }
        else {
            Log.d(TAG, "barcode data is null");
        }
    }
    else {
        Log.d(TAG,"no barcode detected");
    }
    return barcode != null;
}

graphic variable is always Null

Anyone faced this problem? Can you let me know how to resolve it? Thank you so much!

Answer 1

So I guest you are new to Android Mobile Vision, in the new version of Google Play services (v9) they temporarily disabled the feature due to a serious bug in that feature, you can check the release note here:

Answer 2

As @Vietnt134 have already answered, Android Mobile Vision is temporarily disabled.

You can follow this topic to know if something knew came up: https://github.com/googlesamples/android-vision/issues/98

People are pretty mad with Google about this. I hope they solve this quickly.
