In this article we are going to explore how we can detect, intercept and reject incoming phone calls on different Android versions.
In this article we are going to build simple Notes App that will use NestJS backend. In order to start backend app please download it’s source code and check it’s README.md:
Nest (NestJS) is a framework for building efficient, scalable Node.js server-side applications.
Nest provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled and easily maintainable applications.
The main reasons why you should consider to use NestJS as framework in your projects is because it’s very powerful but super friendly to use, documentation is very easy to understand, provides very easy development and testing, supports Typescript and GraphQL etc.
In our project we are going to build simple backend application for storing and retrieving notes.
At the bottom of this article you’ll find sample code, so you can check it in case if you have some problems with following the steps described in this article. …
Notifications about new articles, price changes, product offers are expanding interactivity scope of mobile applications.
A notification is a message that pops up on the user’s device. Notifications can be triggered locally by an open application, or they can be “pushed” from the server to the user even when the app is not running. They allow your users to opt-in to timely updates and allow you to effectively re-engage users with customized content.¹
Push notifications are great marketing tools because they help to increase user-to-app interactivity level.
In this article we are going to explore how we can send push notifications from NodeJS backend application to Flutter Android application, using FCM messages. Device tokens will be stored in MySQL database and in the NodeJS, we are going to validate input. …
AR and VR applications are emerging more and more, providing new possibilities and new perspectives to end user. In this article we’ll explore how AR library called ARCore can be implemented using Unity3D in order to display simple chair object.
Before we dig in into coding, let us remind ourselves what is AR and VR?
Augmented reality (AR) is an enhanced version of reality created by the use of technology to overlay digital information on an image of something being viewed through a device (such as a smartphone camera).¹
Virtual reality (VR) is an artificial environment which is experienced through sensory stimuli (such as sights and sounds) provided by a computer and in which one’s actions partially determine what happens in the environment.² …
Every web application that stores user data need to have login and registration functionality. Besides of email login functionality, we can add login with different social network providers like Google, Facebook etc.
In this article we’ll explore how we can login with email, Google and Facebook. In the article we’ll also cover storing user data in MySQL database and user input validation.
At the end of this article you’ll find code sample, so if you have missed some steps, you can see the complete code sample.
Firstly, we need to put some dependencies in ‘package.json’:
In order to install all the required dependencies, we need to run the following…
Internet of Things (IoT) devices, which are using connection to the Internet in order to send and receive sensor data and powered by affordable micro controllers like Arduino and Raspberry PI, can be seen more and more in our everyday lives. Smart IoT devices can range from microwaves, washing machines to vehicles.
MQTT (Message Queuing Telemetry Transport) is lightweight, publish-subscribe network protocol that transports messages between devices.
It was invented by Andy Stanford-Clark (IBM) and Arlen Nipper (Cirrus Link, then Eurotech) in 1999, and it was used to monitor an oil pipeline through the desert. The main goal was to have a protocol that is bandwith-efficient, lightweight and uses little power, because the devices were connected by satellite link and this was very expensive at a time. …
Laravel framework provides very nice way of subscribing to channels and listening to events. In this article we will explore how we can receive broadcasted events from Laravel web app, in android application, using WebSockets.
