When you start exploring the world of app or web design, you will quickly come across user experience (UX). However, UX design is a long field. And despite its popularity, very few designers have an idea about it. Many designers believe that UX design concentrates on the user, but using this principle in real can be pretty more challenging. So, what are the factors that UX designers should deal with while building a new experience for users? Which rules can differentiate good products from bad ones? Check out this blog! What is UX Design Principle? Here’s the list of the best UX design principles to show the capability of UX designers and the diversity of the UX world. Let’s read on to learn more! 1. User-Centric Design This design fundamental is about understanding how to use our empathy when making design decisions in a product. Designers always want to make the best product using their high standards, which can cause them to decide depending on their preference. But a good UX design should be customizable for users, which means forgetting your opinions and preferences. After all, you will design for the users. So, their wishes, pain points, opinion, choices, and requirements are crucial. You must invest your time and effort in knowing your users. 2. Consistency Users want products to maintain consistency with the products they have earlier used. If your product is familiar to users, they will easily learn it with a better experience. Therefore, designers don’t need to rebuild every design part. As consistency is crucial, designers usually move to design languages. A design language is a set of instructions for creating products for a specific format or device. For example, you will need to follow Apple’s Human Interface Guidelines for designing iOS apps. You might need to refer to Android’s Guidelines or Google’s Material Design Guidelines for developing Android apps. 3. Accessibility Considering accessibility and design is one of the vital UX design rules. The designer must ensure that many people can use the method. Moreover, it implies that people may also use the UX design that features some flaws. As a designer, you need to ensure that there are no hindrances. One example of how accessibility in design helps users is putting labels outside text entry fields rather than inside them. It supports screen readers reading them for visually challenged users, although it notifies them what data goes in every text field. Likewise, utilizing a high contrast between background colors and text helps visually challenged users and users in low-light settings read the screen properly. 4. Hierarchy Hierarchy is another key UX design principle. Using this method at the initial design stage gives you several benefits. It allows the users to browse your app or website more easily and discover what they are searching for. Furthermore, it is crucial because it enables you, as a designer, to see precisely how your app or website functions. It can ease your function as a designer. Using the hierarchy method in the design must begin with creating an information hierarchy. You can use it for building a site map. And from the site map, you can create a design hierarchy that can interlink your pages logically and consistently. 5. User Control User control forms in several ways in UX, but users usually have a great experience controlling their activities and using your product. A crucial part of user control is allowing users to correct their errors. For example, when a user starts building a new item like an event or email, a Cancel button must let him leave the task. An Undo button can also save them for reversing an unwanted or unintended activity. Another method of improving user control is helping more progressed users boost their efficacy. Keyboard shortcuts can help in this matter. Moreover, macros and templates can also help users achieve repetitive actions more effectively. Combining products and features can also help users move content, and advanced searching helps them discover what they seek more effectively. 6. Context Context is a crucial part of users’ interaction approach with your designs. In this matter, context means focusing on the devices users can use to access your mobile app or web page. Furthermore, it focuses on how mobile browsing is major web traffic. Contextual designing also means focusing on many other factors. Usually, location is a contextual factor, but you cannot overlook many other factors, such as users’ emotional condition, the available time, and the gadget they will use. These factors will perhaps decide the users’ behavior once your design creates a strategy to boost the user experience. 7. Usability Designers are cautious for several reasons regarding their design’s usability. Creating better usability is the best thing to offer the users. It’s about checking whether your users can do activities comfortably, your product functions properly, and it does its job. Your product may fail to serve the users if its usability fails. The main challenge for beginners is that usability does not handle black and white. Many design teams follow different rules of good usability. The main thing with this UX design rule is that beginners know the necessity and flexibility of usability in their tasks. A few teams follow higher usability standards that can be tough to reach. Moreover, this convenience enables design teams to fix the bar very low, creating a susceptible product to puzzled users or user disclaimer. 8. Animations Animations are one of the best ways to please your users. They add movements to your website and give a real experience to the target audience. Animations can help the target audience know about a website’s functionality if done correctly. Moreover, the target audience will possibly keep the smallest details in mind. Thereby, it would help if you did not skip the animation as playful pleasure works unimaginably. 9. Confirmation Designers’ main target is to prevent mistakes. When users unintentionally delete a product or make a payment, they get a poor experience. Needing confirmation

There are many reasons why design roles are not the same. With the development of the digital world, the digital design industry is also growing faster. Several functions are now available to deal with various issues with different business requirements. And the difference between product design and UX design comes to mind first. These two design roles look the same, but they have different functions. Designers usually maintain the aesthetics, whether it’s a product or the whole website or app. After all, users prioritize aesthetics. And as per the most recent statistical report, 38% of visitors may leave a website if its layout is not appealing. However, the aesthetic design does not only mean layouts and images. It also implies user experience, which must be suitable for retaining users. Hence, designers play various responsibilities with several specializations. But, every designer plays a distinct role. Although some skills are essential for all of them, specific functions need a particular skill set. Designers’ specialization decides how they can help you meet your business requirements. So, how does a product designer differ from a UX designer? Is there any similarity? Can a product designer become a UX designer? Let’s unveil all the queries in this blog! What is UX Design? UX or User Experience design helps build products that offer a significant experience to users. The design process is all about designing the whole method of getting and combining the product that covers different attributes of design, branding, function, and usability. UX designers ask a few questions regarding the product’s usability and performance. Moreover, they think about users’ desire to accept a product and deliver a beautiful and practical design. What is Product Design? Product design is a combined method of creating a product from start to end. The process includes everything from conducting the market study, recognizing issues, making the product, bringing comprehensive solutions, and other associated activities. Product designers try to solve real-world issues and make easy-to-use products. Their primary duty is to consider various essential product features, which causes a successful design and marketing. Is There Any Similarity Between Product Design and UX Design? Let’s start by discussing the similarities between the job roles of UX designers and product designers! These two design job roles try to create user-friendly, satisfactory products to achieve the end user’s objectives. Here are the points that showcase the equivalence of these two design job roles: Accurate levels of tailoring to customize the office for the absolute user experience Convenient workflow and ease of use Creating genuine scopes for upgrades, user feedback loops, and add-ons Interesting position of workflow artifacts, like icons, menus, and buttons. We can see that UX designers and product designers have many similar targets. So, how do they differ from each other? Let’s find out below! What is the Difference Between Product Design and UX Design? The main difference between these two design job roles is in their aspects. A product designer is more calculated, whereas a UX designer is more strategic. So, how do they differ in every aspect? 1. Designing Methods As earlier discussed, the working methods of product and UX designers are different. The primary responsibility of UX designers is to describe how a product feels. For this, they create interaction patterns and write product usage scenarios. They create a prototype for a user interface. Moreover, they record user activities through various testing tactics like email surveys and A/B testing. On the other hand, product designers usually build the feel and look of the entire product. They give information about the functions of some specific parts of the product. Moreover, they find a market scope and make plans for applying the solution to the issues. 2. Targets and Responsibilities Responsibilities and focus also decide how a product designer differs from a UX designer. A product designer primarily focuses on the business needs more than a UX designer who is initially concerned with user requirements. For instance, a product designer is concerned about the product designing method’s compatibility with other business targets. However, a UX designer solely focuses on users’ different usability issues. Hence, responsibility is a significant factor in deciding between a UX designer and a product designer. 3. Skill Set Needed The skillset is the most significant difference between product design and UX design. Although the basic things will be similar, the specifications are different. Here’s how we can compare the skills needed for these two specializations: Furthermore, a product designer should have curiosity. They must be good at logical and analytical thinking. A strategic mindset is compulsory for a product designer, as they work with planning and designing. And in a nutshell, they should be deeply knowledgeable about the market and the product. UX designers need not be so curious or empathetic. They must be efficient in studying and arranging data. Often, they work with UX copy; hence, they should also have good writing knowledge. 4. Tools Required The tools both designers use also decide the difference between them. Generally, both of them depend on the same design software, incorporating prototyping tools. Moreover, product designers use sketch and mind mapping tools, whereas UX designers use interactive and wireframe design tools. Although their primary aims are the same, the connection between UX design and product design shows the difference between their ways of operation. Both of them can fulfill your business requirements. 5. Qualifications Required for Designers There is no significant difference between the qualifications of product designers and UX designers. They are even the same in this matter: Professional experience in the desired sector Degree with an appropriate specialization Precise knowledge of design methods (planning, instructing, and application) The required qualifications for these two designers may vary from company to company; however, the mentioned qualifications are fundamental. 6. Salaries of Designers Salaries for product and UX designers vary based on their skills, experience, location, and organization. The salary range for designers never remains the same. Since they are in high demand, their salaries keep increasing daily. As per the

Hence, we can see that healthcare organizations accept new technologies and spend more on tech growth. Let’s explain cloud computing a bit and what role it plays in shaping the future of the healthcare industry! What is Cloud Computing in Healthcare? Cloud computing in healthcare is all about applying remote servers used through the internet. It helps to store, handle, and process medical information. Cloud storage is convenient for healthcare experts and medical institutions to use online servers to store a massive amount of data securely. Generally, IT experts maintain such servers. With the advent of the EMR (Electronic Medical Records) Mandate, medical companies have embraced cloud-based solutions to store and secure their patient records. Furthermore, healthcare organizations that did not plan to shift current data centers to the cloud also adopted cloud-based solutions. Top Advantages of Adopting Cloud Computing in Healthcare Here are some benefits of implementing cloud computing in healthcare: 1. An Affordable Solution for Storing Healthcare Data Healthcare providers produce massive amounts of digital data every year. These include lab tests, insurance claims, EMRs, and prescriptions. Cloud technology helps handle that data efficiently. When cloud computing offers more data storage, cloud-based analytical tools can use data more and change it into meaningful information. 2. Growth of Telemedicine The application of cloud computing in healthcare has accelerated the rise of telemedicine. Cloud-based apps and telehealth systems help share healthcare data, offer patient health insurance during treatment, prevention and recovery, and enhance availability. Furthermore, many apps feature more enhanced functions like virtual analysis of medicine consumption or doctors’ appointments through video conferencing. In short, cloud computing is the key to enhanced medical care via telemedicine. 3. Improved Patient Experience Doctors can ensure better patient involvement by providing real-time access to lab test reports, medical information, and doctors’ notes using cloud technologies for healthcare. It helps patients maintain their health more precisely with better knowledge. Furthermore, due to cloud computing in healthcare, patients don’t go through unwanted tests or extra prescriptions. 4. Enhanced Collaboration The application of cloud technologies in healthcare improves collaboration. Due to the EMR in the cloud, patients no longer require individual medical records while visiting a doctor. Doctors even can share data, check earlier consultations with other healthcare professionals, and share data. It saves time for doctors and patients and aids in more precise diagnosis and treatment. 5. Convenient Interoperability Interoperability is all about creating data integrations via the healthcare system, regardless of the source of data storage. Cloud solutions enable interoperability in healthcare and make patients’ information accessible for flexible distribution and getting insights to facilitate healthcare delivery. Cloud computing in healthcare allows medical professionals to access patients’ medical data collected from numerous sources, distribute it among primary stakeholders, and deliver on-time protocols. Types of Cloud Computing in Healthcare The types of cloud computing in healthcare can be classified from two viewpoints: Deployment and Distribution. 1. Distribution Model SaaS (Software as a Service): Providers offer IT infrastructure, and clients deploy apps and operating systems. IaaS (Infrastructure as a Service): Providers provide an operating system and IT infrastructure, and clients deploy apps. PaaS (Platform as a Service): Providers offer apps, an operating system, IT infrastructure, and other elements inside an easy-to-use platform. 2. Deployment Model Community: A specific group with similar preferences and goals can utilize the technology. Private: One specific client can utilize cloud technology. Hybrid: The technology integrates multiple clouds with various access options. Public: Common people can use the technology. Cloud Computing in Healthcare Comes With Risks Despite all the advantages that healthcare cloud computing offers, there are still some issues. Let’s have a look! 1. Restricted Ecosystem The only acceptance of cloud solutions in healthcare cannot make the whole industry productive and efficient. To reap the benefits of this technology, healthcare organizations need to use Artificial Intelligence, the Internet of Things, and Data Management technologies. 2. Lack of Experts You can hardly find expert developers in the healthcare software domain to carry the expertise for integrating new technologies in the industry. Likewise, it’s tough to find cloud professionals in the health domain. 3. Security Challenges Storing healthcare data is the primary point of adopting cloud technology. However, it comes with security risks also. Due to the primary cloud setup, a company’s data share on the server with other companies and the remote systems to individualize them may fail. It causes a situation where healthcare agencies fail to adopt cloud solutions. 4. Issues in Adopting Technologies Moving from the legacy framework to cloud technologies needs to transform the whole task management process. Healthcare agencies need to teach everybody how it would be helpful in their daily tasks. How to Avoid Risks While Applying Cloud Computing in Healthcare? The application of healthcare cloud computing is a multi-phase process that needs collaboration between a healthcare organization and a technology provider. Moreover, it would help to consider some measures to avoid risks associated with cloud technologies. 1. Decide Your Objectives First, understand the requirement of cloud systems in your healthcare business. Otherwise, you cannot list out the things that need cloud solutions. Some reasons for applying cloud technologies are: Saving expenses Compliance management Security improvement Data protection and better backups Understanding the key objectives helps you communicate with your technology provider. And they can provide tailored cloud computing solutions according to your business requirements. 2. List out the Things to Switch to

An Introduction to React JS React is an open-source JavaScript library that developers use for UI building. It helps fix issues of partly updated web pages. React JS is essential for building single-page app development.

Flutter is one of the most popular cross-platform mobile frameworks by Google. The developers have widely adopted the framework across the world, hence there is a loop of updated versions of Flutter, and the latest is Flutter 3. Today we are going to talk about what are the best practices for Flutter app development, referring to this blog will simplify your process of developing an app with Flutter. Best Practises for Flutter App Development Here, you will learn the best practices for Flutter developers to improve code quality, readability, maintainability, and productivity. Let’s get cracking: 1.  Make the build function pure The build method is developed in such a way that it has to be pure/without any unwanted stuff. This is because there are certain external factors that can trigger a new widget build, below are some examples: Route pop/push Screen resize, usually because of keyboard appearance or orientation change The parent widget recreated its child An Inherited Widget the widget depends on (Class. of(context) pattern) change Avoid: Should be like this: 2. Understanding the concept of constraints in Flutter There is a thumb rule of a Flutter layout that every Flutter app developer needs to know: constraints go down, sizes go up, and the parent sets the position. Let’s understand more about the same: A widget has its own constraints from its parent. A constraint is known to be a set of four doubles: a minimum and maximum width, and a minimum and maximum height. Next up, the widget goes through its own list of children. One after another, the widget commands its children what their constraints are (which can be different for each child), and then asks each child what size it wants to be. Next, the widget positions its children (horizontally in the x axis, and vertically in the y axis) one after the other. And then, the widget notifies its parent about its own size (within the original constraints, of course). In Flutter, all widgets give themselves on the basis of their parent or their box constraints. But this has some limitations attached. For instance, if you have got a child widget inside a parent widget and you would want to decide on its size. The widget cannot have any size on its own. The size of the widget must be within the constraints set by its parent. 3. Smart use of operators to reduce the number of lines for execution Use Cascades Operator If we are supposed to perform a sequence of operations on the same object then we should opt for Cascades(..) operator. Use spread collections You can use spread collections when existing items are already stored in another collection, spread collection syntax leads to simpler and easier code. Use Null safe (??) and Null aware (?.) operators Always go for ?? (if null) and ?. (null aware) operators instead of null checks in conditional expressions. Avoid using “as” operator instead of that, use “is” operator Generally, the as cast operator throws an exception if the cast is not possible. To prevent an exception being thrown, one can use is. 4. Use streams only when needed While Streams are pretty powerful, if we are using them, it lands a big responsibility on our shoulders in order to make effective use of this resource. Using Streams with inferior implementation can lead to more memory and CPU usage. Not just that, if you forget to close the streams, you will lead to memory leaks. So, in such cases, rather than using Streams, you can use something more that consumes lesser memory such as ChangeNotifier for reactive UI. For more advanced functionalities, we can use Bloc library which puts more effort on using the resources in an efficient manner and offer a simple interface to build the reactive UI. Streams will effectively be cleaned as long as they aren’t used anymore. Here the thing is, if you simply remove the variable, that is not sufficient to make sure it’s not used. It could still run in the background. You need to call Sink.close() so that it stops the associated StreamController, to make sure resources can later be freed by the GC. To do that, you have to use StatefulWidget.dispose of method: 5.  Write tests for critical functionality The contingencies of relying on manual testing will always be there, having an automated set of tests can help you save a notable amount of time and effort. As Flutter mainly targets multiple platforms, testing each and every functionality after every change would be time-consuming and call for a lot of repeated effort. Let’s face the facts, having 100% code coverage for testing will always be the best option, however, it might not always be possible on the basis of available time and budget. Nonetheless, it’s still essential to have at least tests to cover the critical functionality of the app. Unit and widget tests are the topmost options to go with from the very beginning and it’s not at all tedious as compared to integration tests. 6. Use raw string A raw string can be used to not come across escaping only backslashes and dollars. 7. Use relative imports instead of absolute imports When using relative and absolute imports together then It is possible to create confusion when the same class gets imported from two different ways. To avoid this case we should use a relative path in the lib/ folder. 8. Using SizedBox instead of Container in Flutter There are multiple use cases where you will require to use a placeholder. Here is the ideal example below: The Container is a great widget that you will be using extensively in Flutter. Container() brodens up to fit the constraints given by the parent and is not a const constructor. On the contrary, the SizedBox is a const constructor and builds a fixed-size box. The width and height parameters can be null to specify that the size of the box should not be constrained in the corresponding dimension. Thus,

An Introduction to Flutter 3 So, here we are talking about Google yet another masterpiece Flutter 3 that is created to accomplish its motive by being built with more platforms. With Flutter 3, you can craft Avant-garde experiences for 6 platforms from a single codebase, by helping developers with productivity left to put effort into other tasks and allowing startups to put forward new ideas to the full addressable market from the very beginning. In Flutter’s earlier versions, Google supplemented iOS and Android with web and Windows support, and now Flutter 3 adds stable support for macOS and Linux apps. The motive is to help you with the flexibility to have the complete benefit of the underlying operating system while sharing as much UI and logic as you please. How did Flutter 3 Launch? The Journey It will not be a stretch to say that Flutter has been doing miracles so far. If we talk about the period when Flutter was launched to revolutionize the domain of app development, we will be walking miles together to continue to chat! Whether it is about merging the iterative development model of the web with hardware-accelerated graphics rendering or pixel-level control that were earlier the preserve of games. In the last four years since Flutter 1.0 beta, Google has been persistently working on developing these foundations, by creating new frameworks and new widgets, and deeper integration with the underlying platforms. All along with a rich library of packages and multiple performances and tooling improvements. As Google’s innovation continued to set benchmarks, many industries started investing their effort in the same; building apps with it that took it to the figure of 500,000. To top it, the giant data researchers like data.ai quoted Flutter is used by big-time platforms WeChat, SHEIN, Tabcorp, and many other prominent platforms. 91% of developers mentioned that Flutter is a relatively smooth platform and takes a lot less time to create and publish an application. 85% of developers cited that they got to publish their app on more platforms than earlier. What’s New in Flutter 3? Here’s what you will see next in Flutter, stay tuned for more insights Firebase Support in Flutter It is not just about the UI framework, but the app publishers need an extensive set of tools to allow them to proceed in terms of building, releasing, and operating your applications along with services like data authentication, cloud functionality, device testing, and data storage. Services like Sentry, AppWrite, and AWS Amplify have got flutter’s back for improved functionality. About 63% of the developers use Firebase in their applications. In order to best reflect that reality and Flutter’s persistent growth, the suite of Firebase plugins for Flutter is now turning into a fully-supported key part of the Firebase offering. This means the plugins now fall under Firebase’s repo and website. Moreover, Google is working on creating new flutter widgets that make it even smoother to use firebase in your application. Also, you are now able to get a hold of errors by using the Firebase Crashlytics plugin, this gives you an overview of your app’s stability with which you can fix the bugs merely by tracking the errors. The features are mainly about critical alerting metrics like “crash-free users” that are built to help you in keeping up with the stability of your application. Flutter Casual Games Toolkit Good news for all the game developers out there! Not only is flutter doing miracles for the applications, but games are also in the queue. Google is sharing a casual game toolkit which is a suite of templates, guidelines, and tutorials for game developers who want to invest their effort in flutter. So far, flutter was all about the apps and their functionality; Google has opened yet another door of expansion for flutter! Quite a few games have been released in the market that is built with flutter. Game developers can also take a tour of the flame game engine to get additional insights into how flutter works with games. macOS and Linux Support Back when flutter was released, it received a good amount of appreciation from the developers’ community. Flutter is known to be the most dynamic cross-platform development framework up until today. After starting with just Android and iOS app support, the framework can also officially be used to build apps for Windows, Web, and embedded devices. As flutter 3 is launched, the developers that were earlier doing the labour of adding platforms have now come to cease. As of now, flutter developers can create applications for macOS as well as Linux devices without facing any hurdles. Dart 2.17 The latest version of Flutter also comes up with a new update for the Dart SDK, with the new language version 2.17. These improvements to Dart are accessible for all developers, regardless of whether you use Flutter or not. The hallmark feature of Dart 2.17 is the ability for developers to extend enums and override its default functions, too. This enables enums to act quite a lot like custom-written classes. Web and Mobile Updates in Flutter 3 Here you will see the key features of Flutter 3 in terms of web and mobile Mobile Updates iOS Variable Refresh Rate Support Flutter 3 will be supporting variable refresh rate on iOS devices having ProMotion displays, along with iPhone 13 pro and iPad pro. Flutter apps can contribute at 120 hz refresh rates that were earlier limited to 60 hz on these devices. The increase in hz helps have a smoother experience during animations. Foldable Phone Support Flutter 3 will be able to support foldable mobile devices as well by having a collaboration with Microsoft. These new features enable developers to have dynamic and productive experiences on foldable devices. Streamlined iOS Releases Now Flutter 3 comes up with a new option to create an ipa command for the simplified launch of your iOS application. Web Updates Web App lifecycle With Flutter’s new lifecycle API for web applications, you

Google I/O is an annual event that Google conducts to announce its biggest software changes and updates. Google I/O 2022 took place from May 11 to 12, bringing with it some significant changes. The event covers some notable declarations for Android developers: Exciting new features to make Android app development easier Improvements in wearable applications and advancements for big screens Enhancements to Android Studio and Jetpack Compose A revamped Google wallet Key Announcements for Developers at Google I/O 2022 Google I/O has always been mainly a developer-focused event. Here are the most important announcements Google made during and after the I/O developer keynote. 1. Android 13 Beta Now, the second Android 13 beta is also available. You can prepare your applications for the most recent privacy and security features, such as, enhanced permissions for pairing with handy devices and using media files, the privacy-safeguarding photo selector, and the new notification permission. You can make your application more robust by accessing features like themed app icons and app-specific language assistance. Moreover, you can develop by following modern standards like Bluetooth LE Audio and HDR video. You can try Android 13 Beta on some particular foldables, tablets, and phones. 2. Jetpack Compose Google launched Jetpack Compose 1.2 Beta, which addresses one of the most well-known bugs by adding includeFontPadding, an adjustable parameter. It allows more accurate text alignment within a layout, which is why Google suggests setting this value to improper. Jetpack Compose 1.2 also launches downloadable fonts, helping you explore Google Fonts reversely. You can also decide on fallback fonts with an easy setup. Currently, Jetpack Compose supports Android’s text magnifier widget. The earlier version, i.e., Compose 1.1.0, took this magnifier to selection inside the text fields. And the latest version supports the magnifier in SelectionContainer. Furthermore, it has enhanced the magnifier to match the exact functions and behaviors of the Android magnifier in Views. 3. Android Studio Google also announced some new advancements to the toolset used for Android app development. There are two Android Studio launches: Android Studio Electric Eel, which is a Canary release, and Android Studio Dolphin, which is in Beta. The Android Studio Dolphin allows developers to check how frequently composables can recompose with the Layout Inspector. Lots of recompositions indicate that it is possible to optimize a composable. Moreover, Dolphin includes an Animation Coordination tool that helps developers see and scrub through the animations rapidly. Also, it adds a MultiPreview annotation so developers can develop for different screen sizes. On the other hand, Android Studio Electric Eel features a recomposition highlighter that envisions when and which composables recompose. 4. Flutter 3 Google also introduced Flutter 3 at its I/O 2022 event. The organization’s cross-platform app development suite is growing with newly built assistance for Linux and macOS. It also adds enhancements to Firebase integration, the Casual Games Toolkit, quicker compilation speeds on Apple Silicon Macs, and other new functionality and productivity features. Furthermore, you will get better support for Google’s Material You design language. Flutter 3 also coexists with the launch of Dart SDK 2.17. 5. Large Screens and Foldables At Google I/O 2022, Google launched Android 12L, i.e., larger screens like tablets and foldables. These have more screen space for features like multitasking, column-based layouts from the system menu, and a split-screen mode. Improvements in Android 13 provide a delightful experience of creating and designing adaptive UIs. Google offers three starter layouts, known as canonical layouts. They help start projects with large screens. feed supporting panel list-detail view These are beginner projects for basic use cases. New breakpoints that help you convert your UI depending on the space for various devices are: expanded medium compact You can find these predetermined classes in the JetpackWindowManger 1.1 library. The Jetpack DragAndDrop library is another notable library to create engaging UIs. It offers you helper classes to make dragging and dropping more convenient. Another one is Slidingpanelayout, which helps mix fragments intuitively. 6. Health Connect Google also announced Health Connect, a new platform to explore health data quickly and safely across Android devices. It is Google and Samsung’s joint collaboration, which Samsung Health, Google Fit, and Fitbit are embracing. Health Connect eases connections between applications while helping to reach more users with less effort. So, you can smoothly use and write users’ health and fitness information in your application. You need to download the Health Connect SDK as a Jetpack Library and enjoy using it. When users give consent, Health Connect collects information from all the apps on the Android device and stores the data in an on-device datastore. It provides the users with complete information and knowledge about their fitness data. Presently, Health Connect is available in Alpha via the Jetpack Health API. 7. Firebase At Google I/O 2022, the Firebase team debuted Firebase Extension events. It allows developers to improve the extensions’ functionality with their code. Also, new third-party extensions for payment processing, search, and marketing launched by Typesense, RevenueCat, Stream, and Snap are now accessible in the Firebase Emulator Suite. Now you can deploy the Firebase web applications developed with Angular Universal and Next.JS using one command: ‘firebase deploy’. We expect that assistance for other web frameworks will also come soon. Firebase has updated its Crashlytics support to lower the effort it needs to get started, get alerts from Crashlytics, log on-demand fatal issues in applications, and group Flutter crashes more potentially. Moreover, Firebase gives better support for App Check integration with the new Play Integrity API, Swift language, new alerts in Performance Monitoring, and new functionalities and features in App Distribution, including auto-deletion, easy group access, bulk tester handling, and the capacity to inform testers about a new version inside the app. 8. Google Wallet Google declared its first wallet app in 2011. It underwent many changes, and ultimately, became Google Pay in 2018. At I/O 2022, Google announced a revamped, new Google Wallet to bring its old wallet back. Google wants to replace the physical wallet so users can store their debit

The app acts as a curated collection for all the Substack newsletters subscriptions, kind of like an RSS reader specifically for Substack writers. Users can view a feed of the latest newsletters they subscribe to instead of sifting through all the other spam and work emails in their inbox. The app provides a reader view for these posts too. In addition, the app brings in all the post comments that one would find on the web version of these newsletters. Substack says its news app is beneficial for its writers, too. Readers will be able to easily access all of the content they subscribe to, including podcast and video content. Plus the app’s discovery page will help subscribers find new writers they might be interested in as well. Hamish McKenzie, the company’s co-founder, shared his thoughts on the new app on Twitter, likening it to an RSS reader. He even invoked an old favorite from Google that was shut down years ago, Google Reader. McKenzie mentions that in addition to curating Substack newsletters, the app can also pull in any RSS feed, mingling your favorite blogs and websites with the platform’s newsletters. This feature is hands down the most interesting feature. Is Substack planning to go further down the RSS reader route with its app? It likely depends on how many readers actually use it. Again, RSS readers are still reeling from Google Reader’s closure. While there have been successful replacements, many still feel that what made Google Reader so great has yet to be replicated. Substack has faced its fair share of controversies in recent years. Some writers have left the platform due to the company’s stance on content moderation and misinformation. Its new app won’t really affect that in any way, but perhaps it can help strengthen the company’s argument that it’s committed to diverse content. The Subtack app is currently available for iPhone and iPad. An Android version is also in the works.
