Programming has been one of the most in-demand and highly-paid skills for the last two decades, and the demand is only increasing. In addition to this demand and popularity in the market, working as a developer also provides a lot of flexibility. You can work from wherever you want and contribute to projects all around the world. All of these reasons make software development highly compatible with the freelancing lifestyle.
Those days have long passed when cross-platform mobile applications used to have a single avenue—React Native. Things have changed very fast as people looked for new ways to gain more and more users in the mobile app domain.
Technology has made our lives easier with several forms of implementation that are seen in different professional fields. As most individuals began to efficiently program computers, programming languages with powerful tendencies and functionalities were born.
An introduction to Kotlin coroutines compared to Futures/Promises such as Reactor’s Mono or Java’s CompletableFuture
Most modern mobile apps carry out asynchronous operations, operations that would require the user to wait while the app is busy. Creating nice interactive loaders that match the purpose of your app will greatly improve the user experience in your app. For example the gif above showcases an example where i used an animation of a washing machine as a loading animation in a laundromat Android application. The process of creating animations on android application as been greatly simplified by the guys at Lottie: https://lottiefiles.com/. In this little article, i would outline the steps required to utilize these animations to make awesome loaders for Android.

The technology world is an ever-growing and expanding one, which today has many segments of its own. From that, app development is a highly evolving one. Dart Vs. Kotlin is the prime example of this.
Sometimes we need to close some thread, and we can't just kill the thread as we need to free resources and close connections.
When it comes to the project and its realization, you should take into consideration lots of aspects. And the choice of the technology stack is one of the crucial things that can define how successful and smooth your project will be. Depending on the idea and requirements of your application, site or product, you may find and select a proper programming language (PL).
With Android 9 (API level 28), Google officially started supporting what’s famously known as the notch, a cutout display at the top (because the last two years were the years of the notch?). I can’t claim that but with the notch support, most of the brands came out with their version of a cutout display and with that, we as developers need to think about yet another edge case, especially if we’re working with a completely immersive experience.

This post is about providing a solution in Kotlin for finding all valid IP addresses that can be formed by inserting dots into a given string of digits.
When we are developing an android application it is common to come across a situation where we want to show an image somewhere in the app.The easiest way to handle this is to bundle the image along with the app but the downside to it would be increasing the size of the app. It is not feasible if the application needs to display a lot of high resolution images.So, the next best thing is to host the image in some server and download it from there when the app starts. This is where image caching plays a very important role. We download the image once and store it in our cache and reuse it whenever required. This post will show how we can do that using just one annotation using the ColdStorage library.
