I'm using the ZXing project on an Android application, with the IntentIntegrator method (so the Barcode Scanner app is opened whenever I need to do a scan).
I've noticed that capturing and decoding the image takes almost no time (less than a second), but then it stays with the image captured as a top layer with ~50% transparency for about 2-3 seconds, before sending the scanned information back to my application.
Is this a normal behavior when the library is not embedded into the project or there's something I can do to decrease that waiting time?
It's an old post, but since it doesn't have an answer, let me answer it.
You can set the delay after the scan adding an extra to the intent, like:
IntentIntegrator intentIntegrator = new IntentIntegrator();
intentIntegrator.addExtra("RESULT_DISPLAY_DURATION_MS", 500L);//A long is expected
//all the rest of the code
The constant is defined in the class com.google.zxing.integration.android.Intents
