QRUtils-Android

QRUtils is a set of pre-built, customizable UI components for creating and reading QR codes. It provides different libraries for creating, scanning and reading QR codes. Installation is easy and implementation is easier.

You can expect

A customized QR code on the device's screen in a single line of code
A fully functional QR scanning activity to launch in 1 to 3 lines of code
Customization more than you'll probably need

This README will guide you through. Good luck!

Modules

QRUtils provides separate modules for different functionalities. All the modules listed here are concerned with creating or reading QR codes. See individual instructions for each module to know more:

QRView

QRView is a custom Android View that facilitates the generation of customized QR codes in as less as 3 lines of code. It can even generate QR codes directly from XML attributes. Forget 300 lines of code and multiple classes. This library is all you need. Read more about implementation and usage of QRView here.

QRActivity

QRActivity is a customizable, pre-built QR scanner activity which you can be built with required parameters and launched in order to scan or read QR codes. Other features include flashlight toggle and file picker to read QR codes from image files. Read more about implementation and usage of QRActivity here.

Installation

In your app/build.gradle file add a dependency on one of the QRUtils libraries.

dependencies {

    // QRView : for generating QR codes
    implementation 'chtgupta.qrutils:qrview:0.1.0'

    // QRActivity : for reading QR codes
    implementation 'chtgupta.qrutils:qractivity:0.1.0'
}

Usage

To get started, see the individual instructions for each module:

Sample app

There is a sample app in the app/ directory that demonstrates most of the features of QRUtils. Load the project in Android Studio and run it on your Android device to see a demonstration.

If you encounter a version incompatibility error between Android Studio and Gradle while trying to run the sample app, try disabling the Instant Run feature of Android Studio. Alternatively, update Android Studio and Gradle to their latest versions.

A note on importing the project using Android Studio: Using 'Project from Version Control' will not automatically link the project with Gradle (issue #1349). When doing so and opening any build.gradle.kts file, an error shows up: Project 'QRUtils-Android' isn't linked with Gradle. To resolve this issue, please git checkout the project manually and import with Import from external model.
