How to create a barcode reader application for Android

Even with the release of Google Play services version 7.8 developers have added Mobile Vision interfaces, which provide an API for barcode detection. They read and decode many different types of barcodes, quickly, easily and locally.

Classes for barcode detection and analysis are available in the com The main workhorse is the BarcodeDetector class. It handles Frame objects and returns a SparseArray array of barcodes.

Barcode type represents a single recognized barcode and its value. In the case of 1D barcodes, such as UPC codes, this will simply be the number that is encoded in the barcode. Its value is available in the rawValue field, while the barcode type (i.e. its encoding) can be found in the format field.

For 2D barcodes that contain structured data such as QR codes. the valueFormat field is set to a specific type of value corresponding to the data field. So, for example, if the URL type is detected. then the valueFormat field will return a URL constant and the Barcode object.UrlBookmark will contain the value of URL. In addition to URLs, there are many different types of data that a QR code can store. For example, postal address, date and time of a calendar event, calendar event, contact information, phone number, location on the map and other data, the full list of which is provided in the documentation. Links to documentation here.

Mobile Vision API allows to read barcodes in any position.

It’s important to note that the parsing of all barcodes is done locally, so you don’t need to use a connection to a server to read the data from the code. For example, if you read a PDF-417 linear barcode, which can hold up to 1 KB of text, you can get all the information encoded in it immediately.

So, to develop the application we will need:

  • Android Studio development environment
  • Android 4 Smartphone.2.2 or later version
  • The latest version of the Android SDK, including the SDK tools component. You can get it with the Android SDK Manager in Android Studio.
  • Google Play Services SDK. You can also get it from the Android SDK Manager in Android Studio.

Create a new project in Android Studio. Select the Empty Activity template when creating it.

The next step is to make sure your app can use Google Play services, which includes the Mobile Vision API. You need to update the build file to do this.Your project’s gradle.

The dependency section must have these lines. Update Gradle if necessary.

As of January 1, 2021 in this category, which includes a huge list of textile goods, it is prohibited to sell without a labeling code on the tag. Any Data Matrix code must not only be printed on the product, but also be readable in the application Honest Sign, because this way you can be sure that the product is made of the very material that the seller promises you.

Public scrutiny is an important element of this system.

How to Scan QR Codes and Barcodes by Phone

Now the question arises, how to scan codes with your smartphone camera and which application to choose. I’ve made up my mind and choose the first of the following items, but for comparison, here are two others that are also pretty good and safe. If there is malware in them too, then no one in this world can be trusted anymore.

Scanning a QR code with a smartphone camera

We are talking about a tool that is built into the lion’s share of smartphones. the camera app. It is not necessary to install it, and in some smartphones it is not even necessary to select a separate mode.

All iPhones and some Android smartphones of the latest generations say themselves that a QR code is detected in the frame. They automatically scan it and offer to go to the encrypted address in a drop-down window. If the action suits you, you only have to agree.

The displayed bar will help you to understand if you need to click on the link. On the left iPhone 12 Pro, on the right Samsung Galaxy S21. Both with the latest versions of the OS.

In case your smartphone does not offer such functionality, just switch the camera mode or go to the section where you can find its additional features. Most likely, so the scanner will be in a separate mode, which should be run.

If for some reason you still can’t find the feature you’re looking for, you may simply not have it. Especially if the version of Android or iOS on your smartphone is too old. In this case, third-party applications come to the rescue.

Scan through Google Lens

Google Lens is one of the best alternatives to code scanners in 2021 because you never have to worry about this app infecting your device with malware or showing ads. Not so long ago I told you about the features of Google Lens.

Even if Google will collect some data about you, but the danger of such collection is no higher than just using an Android smartphone. Simply download the app and turn on the Lens option on your smartphone to scan codes.

Kaspersky QR Code Scanner

This alternative to the barcode scanner was developed by Kaspersky’s cybersecurity experts. In this way, you can fully trust it, as it helps to avoid scanning unsafe or malicious codes. If a risk is detected, the app will warn you about it and prevent you from unknowingly going where you shouldn’t.

One of the pleasant features of this application is the history of scans, when you can go to the previously scanned link at any moment.

Why use a barcode scanner app?

You can get product information quickly with a barcode, which you’ll agree makes the hard life in stores easier :). In addition, some applications use a barcode scanner to create a shopping list. To be honest, I have never thought about it but I decided to try it and you know what I liked.

I’ve tried many barcode scanner apps, and I’ve selected 4 of the best ones for you. Here we go!
