Here a curated list of Top 10 Android QR Lawmaking Scanner Library for your App with link to complete documentation provided:

ZXing QR Code Scanner (Coffee)

Android library projects that provide easy to use and extensible Barcode Scanner views based on ZXing.

Zing Scanner Library

To use this library add the following dependency to your build.gradle file.

                repositories {    jcenter() } implementation 'me.dm7.barcodescanner:zxing:1.9.13'

• Car focus and wink calorie-free control
• Portrait and mural screen orientations
• Back and front end facing cameras
• Customizable viewfinder
• Kotlin friendly
• Bear on focus

Code Scanner

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

                dependencies {     implementation 'com.budiyev.android:code-scanner:two.1.0' }              

Add photographic camera permission to AndroidManifest.xml (Don't forget virtually dynamic permissions on API >= 23):

QR Code Reader View (Java)

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

This project implements an Android view which bear witness camera and notify when there'south a QR lawmaking inside the preview.

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

Yous tin likewise use this for Augmented Reality purposes, as y'all get QR command points coordinates when decoding.

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

                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 nearly average code for dealing with setting up QR Code reading simply too provides an like shooting fish in a barrel 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 uncomplicated every bit adding information technology 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 Lawmaking 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
• utilize the forepart camera for scanning
• immediate refresh functionality
• update to 11.0.4 mobile vision SDK

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

                dependencies { 	        implementation 'xyz.belvi.mobilevision:barcodescanner:2.0.three' 	}

QR Parse Library (Coffee)

This lib intend to aid developers to parse the qr text returned from whatsoever qr reader to an elegant grade which you can display in a textview

and the power to return a well formated object which you tin use to get desired field.

Features supported past this library are every bit follows:

• It gives y'all the ability to change the QR reader supervene upon information technology 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 y'all can use to display information technology into text view or use information technology to get specific values
• ability to handle all the actions associated to a QR lawmaking (i.e for contact info it supports the show on map, call, send mail and add to contacts)
• power to use wink light
• support device rotation
• easy to apply

This library is yet to provide back up for Gradle build.

Firebase QR Code Scanning API

Though its non a library but we though this may assistance.

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

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

                dependencies {   // ...    implementation 'com.google.firebase:firebase-ml-vision:22.0.0' }                              

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