      • Kotlin: How It Is A Great Choice For Android App Development?



          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.

                • Suspending over blocking

                  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.

                • Modern Environment for React Native Applications

                  In this article, we will consider the process of setting up a React Native environment using expo-cli, Typescript, and Jest.
                  Typescript will help us avoid development mistakes and write a more efficient mobile application.

                  Modern tools allow integrating Typescript into the development environment. We can also use VS Code that supports Typescript.

                  Integration with React Native will give us the opportunity to use the auto-completion service, code navigation, and refactoring.

                  Expo is a toolkit that simplifies the creation of native React applications. This tutorial will give you an idea of how you can quickly create native React applications using Expo.

                • Why developers love to build native App?

                    In today's world, the rise and use of smartphones have reached to an extent and is continuing to rise higher. There are numerous things on which people are more dependent on fulfilling their daily tasks or usage. Millions of mobile applications are built by developers to make the lives of people more comfortable and convenient. There is a range of reasons to use mobile apps like — playing games, shopping, engagement on social media platforms, accessing news, and other functions.

                    For assuring that the application is working in a perfect condition, it is necessary to make sure that the development process is followed in a certain way while building an app. So why Native app development will be comfortable for your app and not Cross-platform development?

                  • Bluetooth stack modifications to improve audio quality on headphones without AAC, aptX, or LDAC codecs

                      Before reading this article, it is recommended to read the previous one: Audio over Bluetooth: most detailed information about profiles, codecs, and devices / по-русски

                      Some wireless headphone users note low sound quality and lack of high frequencies when using the standard Bluetooth SBC codec, which is supported by all headphones and other Bluetooth audio devices. A common recommendation to get better sound quality is to buy devices and headphones with aptX or LDAC codecs support. These codecs require licensing fees, that's why devices with them are more expensive.

                      It turns out that the low quality of SBC is caused by artificial limitations of all current Bluetooth stacks and headphones' configuration, and this limitation can be circumvented on any existing device with software modification only.

                                With the recent progress in Neural Networks in general and image Recognition particularly, it might seem that creating an NN-based application for image recognition is a simple routine operation. Well, to some extent it is true: if you can imagine an application of image recognition, then most likely someone have already did something similar. All you need to do is to Google it up and to repeat.

                                However, there are still countless little details that… they are not insolvable, no. They simply take too much of your time, especially if you are a beginner. What would be of help is a step-by-step project, done right in front of you, start to end. A project that does not contain «this part is obvious so let's skip it» statements. Well, almost :)

                                In this tutorial we are going to walk through a Dog Breed Identifier: we will create and teach a Neural Network, then we will port it to Java for Android and publish on Google Play.

                                • Translation
                                Google loves easter eggs. It loves them so much, in fact, that you could find them in virtually every product of theirs. The tradition of Android easter eggs began in the very earliest versions of the OS (I think everyone there knows what happens when you go into the general settings and tap the version number a few times).

                                But sometimes you can find an easter egg in the most unlikely of places. There’s even an urban legend that one day, a programmer Googled “mutex lock”, but instead of search results landed on foo.bar, solved all tasks and landed a job at Google.

                                The same thing (except without the happy ending) happened to me. Hidden messages where there definitely couldn’t be any, reversing Java code and its native libraries, a secret VM, a Google interview — all of that is below.

                                  If not to take into account releases for Android and a dozen of abandoned projects just before they were ready, then yes, it is our first game appropriate for more than one platform. How did it all start? Very simply. We worked on another project, let’s call it “project A”, and we’d been working on it for a long time when we decided to make a game during a couple of months and use it to train our marketing skills, and then immediately release our “project A” when we would be more experienced in the promotion of games. But the plan failed and “project A” was kept untouched for the whole year. But this story isn’t about “project A”, it’s about a logical game called «Cubicity: Slide puzzle».
