Failed to set CONTINOUS_PICTURE

[masewo]

With the latest version 3.0.0-dev.1 I get the following error when trying to scan a barcode on an Android emulator:

E/ZXing   (32043): Failed to set CONTINOUS_PICTURE
E/ZXing   (32043): java.lang.RuntimeException: setParameters failed

Even when commenting out following lines there is no scan result:

//        cameraWrapper?.mCamera?.parameters?.let { parameters ->
//            try {
//                parameters.focusMode = Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE
//                cameraWrapper.mCamera.parameters = parameters
//            } catch (ex: Exception) {
//                Log.e("ZXing", "Failed to set CONTINOUS_PICTURE", ex)
//                callbackFocus = true
//            }
//        }

That's not really a bug. The message occurs when the barcode was scanned, the scanner shuts down and zxing try to perform auto focus.

As you can see, the barcode is recognized:

But I'll remove the confusing message in the next release.
