  • In this video, we're going to discuss how to create a QR Code Generator and Reader in Android. A Quick Response Code or a QR Code is basically a two-dimensional bar code used for its fast readability and comparatively large storage capacity. Inside our application, we'll be adding the functionalities to generate a new QR Code as well as to scan the existing QR code. So, let's get started now.

    Solved problems with CAMView dependency libraries in QRGenerator, created libraries and copied content. It failed through the server, because on the remote Maven server, and through dependency it is not synchronized, add the libraries to the project and everything will work. If someone needs the source, leave a comment under the post.
