问题 I'm using mergZXingGetBarcode (mergAndroid) on Livecode to build an Android app that basically requires user to scan QR to login. If the user device is not installed with the specific barcode scanner developed by ZXing Team, when the scan button is clicked, it looks as though there is no function being carried out (in user's view).
