iOS has added support for getUserMedia in WKWebView since iOS 14.3 and WebAssembly since iOS 11. So it is possible to use the JavaScript version of Dynamsoft Barcode Reader to scan barcodes and QR codes in WKWebView. In this article, we are going to build a demo app to illustrate...

Google Chrome has getUserMedia support since v53 and WebAssembly support since v57, which makes it possible to use Dynamsoft Barcode Reader to scan barcodes and QR codes in the web context. The WebView component included in modern Android uses Chrome as its backend, so we can also run a barcode...

Normally, we scan barcodes and QR codes from live camera streams or static images. But sometimes, we may need to read barcodes from video files, like scanning the barcodes on a long shelf and evaluating the performance of live scanning. A video contains rich information. A state-of-art mobile phone can...

SwiftUI is a powerful UI framework for building native apps for any Apple platform. This article guides you through the process of creating an iOS QR code scanner using SwiftUI, Dynamsoft Camera Enhancer and Dynamsoft Barcode Reader on M1 Mac mini. Dev Environment on M1 Mac mini Xcode 13.2.1 Cocoapods...

In my previous article, I demonstrated how to implement a simple Android QR code scanner. Based on the codebase, I am going to do something more interesting - integrate the YOLOv4 tiny model that I trained for QR code detection into the Android project. Is YOLO tiny competent for real-time...

A QR code scanner application primarily consists of two parts: camera preview and QR code scanning. There are many Android QR code scanner apps downloadable in the Google Play Store. However, it is more interesting to create a QR code scanner by yourself than to use an existing one. This...

Although almost every Android phone is equipped with cameras, some Android devices, like TV boxes and kiosks, may not have cameras built-in. An easy way to add extra camera functionality to these devices is by connecting with a USB camera if they support USB-OTG. Starting from Android 9, the Android...

If you want to create a QR code scanner for both Windows and Android from a single codebase, what is the best way to do it? If you have read my previous article, Flutter could be your answer. However, it takes time to develop Flutter plugins. The cons of Flutter...

There are many QR code tools and SDKs available on the market. For Android development, Google ML Kit is no doubt a good choice, which is free and supports general QR code detection. However, it cannot satisfy the requirement of high-density QR code detection. As a commercial barcode SDK, Dynamsoft...

Camera control and barcode reading are two essential parts of a barcode scanner. Dynamsoft Barcode Reader is an advanced barcode reader with an easy-to-use Android library. The implementation of the barcode reading function is simple and straightforward. Making a good camera app, however, is not easy. In Android, there are...

Previously, I shared an article demonstrating how to use Camera2 APIs and Dynamsoft Barcode Reader to build a simple Android barcode reader app. In that demo project, the barcode decoding part is implemented in Java, which apparently has room for improvement. If we can get the pointer to the native...

Assume you apply barcode technology to the logistics conveyor belt for scanning parcels. A problem you may face is how to recognize barcodes from blurred images. Although we can use advanced algorithms to deal with this complicated case, we’d better improve the image quality as possible as we can. A...

Last week I made a warm up for Kotlin, getting started to learn tutorials and reference. Now it is time to take the next step. Since Kotlin is hundred percent compatible with Java, we can use both programming languages without barriers in one project. In this article, I want to...

When building mobile barcode scanning apps for Android or iOS, developers could either choose open source SDKs – ZXing and ZBar, or some commercial mobile barcode SDKs. If you are an Android developer and have installed Android Play Services SDK level 26 or greater, it is convenient to create Android...
