Though not actively maintained, built by David Larazo, This Android QR Code library is a modification of ZXING Barcode Scanner project for easy Android QR-Code detection and AR purposes.

Android QR Code Scanner Library

This project implements an Android view which show camera and notify when there’s a QR code inside the preview.

Some Classes of camera controls and autofocus are taken and slightly modified from Barcode Scanner Android App.

You can also use this for Augmented Reality purposes, as you get QR control points coordinates when decoding.

To implement this library in your Android project, add the following line of code to your build.gradle (app) dependencies:

      compile 'com.dlazaro66.qrcodereaderview:qrcodereaderview:2.0.3'

QR Reader (Java)

Created and maintained by Nishant Srivastava. The QR Reader android library which makes use of Google’s Mobile Vision API to enable reading QR Code.

The library is built for simplicity and ease of use. It not only eliminates most boilerplate code for dealing with setting up QR Code reading but also provides an easy and simple API to retrieve information from QR Code quickly. Also, it required Google Play Services to work.

Integration QREader is available in the Jcenter, so getting it as simple as adding it as a dependency

implementation 'com.github.nisrulz:qreader:{latest version}'

Mobile Vision QR Code Scanner (Java)

Built by developer KingsMentor, Its a Barcode and QR Code Scanner supported by Mobile Vision Api.

The library is able to:

  • Capture a scanned screen
  • Support two or more barcode format
  • Release a barcode detector
  • use the front camera for scanning
  • immediate refresh functionality
  • update to 11.0.4 mobile vision SDK

Use this library by ading following line of code to your build.gradle (app) dependencies:

dependencies {
	        implementation 'xyz.belvi.mobilevision:barcodescanner:2.0.3'

QR Parse Library (Java)

This lib intend to help developers to parse the qr text returned from any qr reader to an elegant form which you can display in a textview

and the ability to return a well formated object which you can use to get desired field.

  • It gives you the ability to change the QR reader replace it with your choice and the parser will be the same
  • Keep history to all QR codes scanned before
  • parse QR codes to a well-formatted object which contain a raw value you can use to display it into text view or use it to get specific values
  • ability to handle all the actions associated to a QR code (i.e for contact info it supports the show on map, call, send mail and add to contacts)
  • ability to use flash light
  • support device rotation
  • easy to use

Firebase QR Code Scanning API

Though its not a library but we though this may help.

With ML Kit’s barcode scanning API, you can read data encoded using most standard barcode formats. Barcode scanning happens on the device and doesn’t require a network connection.

Add the dependencies for the ML Kit Android libraries to your module (app-level) Gradle file (usually app/build.gradle):

dependencies {
  // ...

  implementation ''

Now go ahead and build your amazing androi QR code scanning app.
