The latest Android 10 update has already created a stir in the Android circuit. However, tech enthusiasts around the world are waiting for the latest addition in Android's operating system.

Yes, you heard it right, I am talking about the Android 11 update, the latest upgrade in the Android’s operating system.

The update has been expected to hit the floors in the official reveal of Android 11 in mid-2020, at Google IO 2020 which will run May 12-14, before being released for Pixel devices in the month of September, and then it will be rolled out for other Android devices from late 2020 through well into 2021.

JavaScript, CSS, and HTML are some of the main technologies that help you to build robust app solutions. So, if you are looking to build smart web applications for your business, then I advise you to jump to my idea of cross-platform and open-source development frameworks right away.

Here is the list of the tech stacks for app developers to use in 2020.

Alright, so you have just planned to hire developers for a Mobile App which could potentially steer your business ahead. The reasons for your decision would be quite obvious on the surface. Mobile App development is a core part of today’s businesses. It provides a near-perfect platform to serve customers through the portable devices they own.

But it’s easy to be a sheep! If you really try to understand this market, you’ll realize that more than half of the apps fail to earn revenue, and a significant amount of them barely cross 1,000 downloads. As per a Gartner report, it was found that barely 0.01 percent apps will find financial success by the year 2018.

Android has always been on the top of the hustle when you think about mobile application development. Android’s smartphone OS Market Share now hovers around 85%. Furthermore, volumes are expected to grow at a five-year CAGR of 2.4%, with shipments approaching 1.41 billion in 2022.

But before you took the plunge in exploring and riding on the waves of changes or hire an android app developer to develop an app, it is important to understand the trends and its implications on the android application development ecosystem.

It is quite observable today that every business requires to leverage the power of the internet and mobile to earn more profit and attract tech-savvy audiences.

5G ( Fifth Generation Wireless Cellular Network) is not just a possibility anymore. The forthcoming of 2020 has unfold avenues for 5G browser capabilities in smartphones.

With the recent 5G rollout, it has been predicted that over 1.4 billion devices will be running on the 5G network by 2025 — accounting for 15% of the global total.

In this article, I want to consider an approach to splitting tasks into subtasks when using Clean Architecture.

The decomposition problem was encountered by the NullGravity mobile development team and below how we solved it and what get in the end.

Analytics is an integral part of a modern mobile application. Analytics allows you to collect user information to develop and improve the product.

Often, collecting information reduces application performance. The process additionally loads the CPU and memory, and this is a high price. Slow operation of the application can cause negative user reviews, lower the rating and lead to loss of audience.

Our android team faced with this problem while working on the next project, which was related to the news. We had to register the display of each news in the list.

Kotlin coroutines are much more than just lightweight threads — they are a new paradigm that helps developers to deal with concurrency in a structured and idiomatic way.

When developing an Android app one should consider many different things: taking long-running operations off the UI thread, handling lifecycle events, cancelling subscriptions, switching back to the UI thread to update the user interface. In the last couple of years RxJava became one of the most commonly used frameworks to solve this set of problems. In this article I’m going to guide you through the end-to-end feature migration from RxJava to coroutines.

Every other person is establishing a startup these days. Is it easy to make it work? Do you know what is the success rate of startups? You would be shocked to know that out of the total startups launched in the year 2014, only 56% of them could make it to the fifth year, i.e. 2018.

Every entrepreneur starts a business with a vision to take it to exceptional heights. The bitter truth is, no matter in which industry domain you are working, you cannot survive for long if you do not perform extraordinarily.

Do you have any idea how many Android apps are there in the world? As of 2019’s first quarter, there were approximately 2.6 million android apps around the globe. That’s a huge number which leads to stiff competition in the market.

There is no other option other than offering a robust and efficient Android app to survive in this flourishing industry. The selection of the right tech-stack is highly important if you want to get a flawless development of your Android app.

We were speaking with a customer last year that builds dozens of mobile applications every year. They said, «We cannot remember the last time we made a mobile app that did NOT include a carousel view.» Many of you have expressed almost identical sentiments to us. So, we are very pleased to introduce a new CarouselView control in Xamarin.Forms 4.4.0. Along with this we also have IndicatorView for displaying the pages or items in the carousel. As well as SwipeView for providing contextual actions to any element in a CollectionView. The release theme of getting things moving would not be complete without showcasing the new GIF animation support for images. Let’s begin right there.

The year 2020 is coming to a close as getting nearer to 2021. The end of 2020 will be the end of a decade in which app development proliferated, and in which software technology reached greater heights.

But as years come by, the importance of apps is only going to increase even further people begin to use technologies such as IoT, chatbots, AI/ML software in their daily lives.

App development includes more than just mobile apps. It also includes development for applications for other types of devices, such as PC, tablets, wearables, etc. However, the growth of mobile apps alone gives great scope for running profitable businesses in this space.

As per research by iResearch, revenue from paid mobile app downloads and in-app advertising alone reached $581 billion dollars in 2020, and reach almost near the trillion-dollar mark by 2023.

The story of another ban.

Have you heard about bans on apps and developers in Google Play? This is just such a story. It’s also an attempt to collect similar cases into one place and offer some kind of plan of action to prevent Google’s unpredictable actions. It isn’t fair to be banned for the legal use of free material. Personally, I like the idea of content licenses such as CC BY-SA, which permits any use, including commercial. Thanks to such licenses, we developers have websites like StackOverflow, where I’ve been elected to be the moderator. Unfortunately, companies like Google don’t respect the ideas behind these licenses. Here's my story.

Popular cloud hosting DigitalOcean has recently launched its new marketplace selling preconfigured images that can help to quickly deploy an application server. It’s much like AWS, but DO is for those already using this provider’s services. Let’s see how to deploy a simple server for WebRTC streaming with a DO account for a $10/month fee based on Flashphoner WebCallServer and how such a server can be of use.

In 2017, Google declared Kotlin as its second official language for Android application development. The language itself proving to be a modern, intuitive and pragmatic programming language. That’s why Kotlin's app development community is growing at a fast pace. For android app developers, using Kotlin with Java can reduce excessive boilerplate code which is a huge win for them.

In order to heighten productivity, Kotlin language comes with amazing functional features that support Java interoperability. It has effectively improved the coding experience of developers by introducing concise expressions, abstractions, and improved syntax.

I frequently hear questions like "How to implement authentication in an Android app?", "Where to store a PIN?", "Hey man, will I be secure if I implement an authentication feature in such a way?" and a lot of the kind. I got really tired answering these questions so I decided to write all my thoughts about it once to share with all questioners.

Every day we hear about new budding software programs. With the rapid advances in the software development industry, new players entering the market and have captured a large segment of the market. So, when you need to track business projects, handle the allocation of assets, and solve other IT challenges, you need help from the top software development companies. However, it doesn’t mean that you should select a software development company on the basis of how appealing it was once. Today, people prefer to check the full profile of a company first and then decide to get their service.

To ease your pressure down, listing here some of the internationally acclaimed software development companies from the development niche. This list has been curated on the basis of a variety of reliable resources like Clutch, GoodFirms, Google SERPs, user's feedback & reviews, different independent review firms including medium.com, themanifest.com, etc. Based on the collected data, I’ve assigned the total score for each of the 10 leaders, and here I represent a list of the top software development companies that are doing best in their domain.

There is a good practice to make your application beautiful and live, and nowadays there are a lot of tools and ways to achieve this. One of them is Shared Element Transition.

In this article I’ll cover a few mistakes which have cost me a lot of time; I’ll show how to avoid them if you decide to implement this kind of transitions with Fragments on application.

This article aims to show how to use Kotlin Coroutines and remove Reaxtive eXtensions (Rx).

Benefits

To start let's consider four benefits of Coroutines over Rx:

Suspending over Blocking

To run non-blocking code using Rx you'd write something like this:

Observable.interval(1, TimeUnit.SECONDS)
    .subscribe {
        textView.text = "$it seconds have passed"
    }

Which is effectively creating a new thread. Threads are heavy objects in terms of memory and performance.

Both are critical in the mobile development world.

You can achieve the same behavior using the following snippet:

launch {
    var i = 0
    while (true){
        textView.text = "${it++} seconds have passed"
        delay(1000)
    }
}

Essentially, Coroutines are light-weight threads but we don't create any real thread.
Here we are using non-blocking delay() function, which is a special suspending function that does not block a thread but suspends the Coroutine.
