Diy android qr code reader2/13/2024 New BarcodeDetector.Builder(getContext()) from the analyzed QR in addition to all this, we create the source of the camera and the associated resolution: // creo el detector qr This class allows us to recognize barcodes and QR codes -which is our case of interest- through the device's camera and return an object of the SparseArray type with the decoded data. Setting up the code reader and camera in our activityĪnd in our activity or fragment we must create an object of the BarcodeDetector type. With our dependency already configured we can now go to our activity and/or fragment and create the objects, events and configurations necessary to have our own QR reader but first we must configure the layout of the activity or fragment: In our manifest we place the use of the camera: Para que el paquete actualice automáticamente podríamos hacer algo así implementation ':play-services-vision:15.+' Configuring the rest of the application for our QR reader The manifest file to handle permissions You should keep in mind that the versions change from one day to the next You can find the latest version in the official documentation at the following link: Implementation ':play-services-vision:15.0.2' The previous dependency gives us access not only to the vision API but also to the entire platform that Google Play offers us, as in our case of interest it is only reading a QR code, we can use the following dependency in our adle: We open our adle file and add the following dependency: Adding the dependency in the adle file in Android Studio Developing our own QR code reader on Androidįinally we come to the area of interest in what is to create our QR code reader on Android first we need to add the necessary dependency in our adle. With the help of a mobile we can recover this information just by pointing the camera towards the QR code and that is the idea and what we will do in the next section of this post where we will detail how to create a QR reader with Android. libraries and there are websites that are responsible for generating QR codes such as the following Generate your free QR code or a personalized one using a programming language as we saw previously. ![]() On the Internet you will find an immense number of ways to generate QR codes We can even create QR codes with PHP, Java, etc. ![]() Where we can process medicines and indicate to the client if the medicine is useful for them, having their profile previously loaded and without the need for the client to provide any information or data manually. and it is because with an Android app we can scan any type of QR code.Īlthough our case of interest is to show the process of creating an Android application to use it as a scanner in an Android app. What is a QR Code used for? and how we can exploit them in our Android appsĪs previously mentioned, QR codes are widely used due to their versatility and great utility They are used in all kinds of products, such as food, up to devices, automobiles, magazines and many other types of advertising, marketing, etc. ![]() QR codes are really useful to manage inventories, share data and information in an easy and very professional way QR codes are currently a fundamental element in any small or large application due to their versatility when using them. gms:play-services-vision, but before that let's see what it is, how a QR code works and how we can use it in our Android applications and webs: What is a QR code?īefore going into the topic of how to develop a QR reader using a native library provided by the people of Google, it is important to know what a QR code reader is and how its structure works, which is what we will explain below.Ī QR code is nothing more than a system that allows information to be stored in a kind of next-generation barcodeĪ QR code is a type of barcode but in two dimensions in which information is encoded in a box like the following In this post we will see how to create a QR code reader on Android in our applications To get a clearer idea of how a QR reader works, there are currently several QR readers on Android that you can find on Google Play to name a few:ĭeveloping a QR reader in our Android application with the Play Service libraryĪs you well know, Google offers a significant amount of functionality that translates into several APIs developed by Google itself that it makes available to us developers through its libraries as well as Play Services as well as supports among many more To do the most common tasks, such as creating an application to read a QR code, it is not necessary to use a third-party library or package the one provided by Google that does all the work for us is enough for us.Ĭreating a custom QR reader (created by ourselves using Android Studio as a software development environment or IDE) is quite simple with Android and we only have to include an external library which corresponds to Google Play services:.
