9 Ways to Enhance Mobile App User Experience

The success of mobile app depends on different factors, and the user experience (UX) is one of them. A good UX can completely turn over the tables. But an optimal UX can only be designed with a thorough understanding of your user base and psychological underpinnings. It is not a one-time task, the users nowadays expect more than just a regular app. A designer needs to be up to date on the latest technology trends. Let us outline the ways through which you can enhance the user experience for a mobile app-

1. Error-Free Functionality

According to the statistical report of Experience Dynamics, 90% of the users stopped using a particular app because of poor performance, and 86% of uninstalled the app due to functionality flaws. However it is difficult to have an app with perfect functionality, but a good designer can achieve 97% of functionality rate. Image result for error free functionality in app

2. Efficient Onboarding

The onboarding determines the success and failure rate of a product. And if the user is having trouble with it, they will end up uninstalling the app. The goal of onboarding is to demonstrate how the users can attain what they are looking for. Image result for efficient app onboarding

3. Usability

It is basically the layout of information, content, design and some other elements which help the user to achieve the goals. Help your user to understand the app. Image result for app usability

4. Reduce Search Effort

If there are many products on your mobile app, the user may end up getting confused. Using better search options like filters, barcode scanner, keyword search etc. It ultimately increases the conversion rates. Image result for search on mobile app

5. Limit User Input

Users hardly like to put a lot of information on a mobile app. Make the login task easier by adding signup via social media handles. Image result for limit user input in mobile app

6. Integrate Behavioral Gesturization

There are certain things everyone is comfortable with. Integrating gesturization refers to the actions the user perform while interacting with your app like swiping, scrolling, pinching, etc. Having some common behavioral gesturization makes the user comfortable using your app. Image result for app usability

7. User Assistance

User assistance is one of the most important things. Calling customer service to resolve a query should not be the only option. Add FAQs, personalized chat process to solve the customer’s queries. Image result for FAQ in mobile app

8. Personalized UX

Personalization not only means storing user’s previous actions but it also refers to the recognizing the user’s shopping pattern so that you can suggest some things to them. Image result for personalized ux in mobile app

9. UI Design

Lastly, a quality UI design is mandatory. Your UI should have a high glanceability rate. Glanceability refers to how easily the visual design conveys the information. Create visual consistency with the color palette, typography, and all other design elements. Image result for ui design User experience is one of the major aspects of a mobile app. Users are always attracted to simple, attractive, and sorted things. So, rather than making it complicated in the name of creativity make it simple. And make sure it looks refreshing and engaging to the user.

8 Reasons for Paying Attention to Mobile Web Performance

In last few years, e-commerce has shifted from desktops to mobile phones. Mobiles are not just another device, they have become a major part our day-to-day life. And everyone knows that they cannot grow their business without considering mobile first. So, if you are still living in the old era, then you should have a good look around, and start paying attention to mobile web performance-

1. Statistics explain the business growth

Image result for statistics business growth Mobile web has a major impact on business growth. There is a rapid growth of business on the mobile web. According to the stats, 55% of all time spent on retail sites takes place on mobile devices. Almost 70% users, use mobile instead of desktop and having a mobile responsive website increases the chances of conversions.

2. M-commerce (mobile commerce) revenue is growing rapidly

Image result for m-commerce revenue Mobile revenues have almost tripled in the US from 2013 to 2011. Almost 16% of overall e-commerce revenue was mobile generated, while it increased by 10.3% in 2017. It is not a small amount- it is around $113 billion in figures.

3. Conversion rates

Image result for m-commerce conversion rate Though the conversion rates for the smartphone are less, they are catching up following the tablets. The conversion rate of mobiles is also increasing rapidly. The users are focusing more on mobiles, so the business should also try to focus on the mobile web.

4. User Expectations

Image result for m-commerce user behavior If your mobile site is still outdated and does not work on mobile browsers properly, then you are definitely losing customers. The user prefers a well-optimized page that doesn’t take forever to be loaded. Slow pages are the most common problem for the users and reduce the site ranking.

5. Slow pages

mobile commerce trend 1: physical and online worlds will continue to converge in 2016 Slow pages increase user’s frustration and decrease engagement during online transactions. The slightest change in website’s speed bothers the user. The only way to solve this problem is by optimizing the app carefully.

6. Mobile users’ expectations

mobile commerce trend 4: mobile moments drive online consumer behavior According to the data and records, a website should be loaded with 3-4 seconds after clicking on the link. But most of the websites does not meet this requirement. Even the most popular website does not meet this criterion. Developers and designers need to work on this fact and make their websites more usable.

7. Poor mobile web performance has its own impacts

Image result for poor mobile web performance There is a huge difference between user expectations and reality. The poor web mobile performance ultimately hits the business. Users usually abandon the site and move on to the next option. It reduces the conversion rates.

8. Slow pages undermine overall brand health

Image result for page is loading It is very obvious that one bad result can convert your customer into a user. It undermines the overall growth and health. There is no denying the fact that a good economic growth comes from good online presence.  

Summing up

As we all know that mobile web performance is extremely important for the business, so rather than sitting back, developers and designers need to work on the websites to enhance user experience which will ultimately help in growing the business.

Struggling between hiring an agency or a freelancer? Here is a solution!

A Guide to Outsourcing Mobile App Development

Outsourcing your mobile development project to a third party is an important decision.  It is dependent on many things and varies according to the situations. Though there are many options for outsourcing your work, but you need to decide which one is best for your business. This guide will give you a good idea about whom should you outsource your business. You need to take many things into consideration including manpower, resources, budget, etc. At the end of this article, you will have a fair idea about which option you will be choosing for your future mobile app development. Top-Emerging-Trends-in-Mobile-App-Development

Let us have a look at the options for outsourcing-

#1 Boutique Mobile App Development Firms

Image result for mobile app development Boutique mobile app development firms are not included in the technology giants. While they have the best services to offer, they are not set-up on the big scale. These firms specifically focus on mobile app development. They don’t keep it as a secondary product. They have strong technical capabilities and specialized platform knowledge. Though these companies are not as big as the business tycoons, but they vary as per different aspects. It includes technical expertise, resources, technology, project complexity, team size, etc. Such companies have the best to offer according to your budget.

#2 Big App Development Firms

Image result for mobile app development They are the basic technology giants. They have different domains under one string. Mobile app development is usually one of their products. While these companies are highly capable, but they lack at certain points. They have thousands of clients working with them due to which the small clients get less leverage over the big one.

#3 Independent or Freelance developers

Image result for mobile app development Let us keep the companies aside, and talk about the freelancers. Freelancers are probably the ones who are already working in a company but work part time to make extra money. Even though you will have the whole attention of the person, but there is a possibility of not getting the best returns. They are comparatively less expensive. Image result for mobile app development

Which one is right for you?

Outsourcing app development work is a decision that needs to be made according to the organizational goals and requirement of the project. Successfully determining these two things will help you to eliminate many options early in the process. After which you need to concentrate on the risk factor, time period, budget, and customization. And deciding these things will dissolve the other half of your search process. Once your company is able to determine the best route, you can begin researching and narrowing down the best vendor options.

Current Trends for Android App Development

Smartphones are ruling the market today. According to research, the number of smartphones users will be growing from 1.5 billion to 2.5 billion in 2019. And this is the reason why the Android market is growing rapidly. There are new trends in the market every day. Let us check out the key trends of Android app development that will define how the market is changing-

#1 Web Apps + AMP

Image result for web amp Google launched Progressive Web Apps Accelerated Mobile Pages (AMP) in 2016. Web Apps are designed to open a mobile app in the browser without downloading the app. Everything is same in web apps and mobile app except it allows you to use the same app in the browser. And these web apps are developed using AMP project’s principals. AMP is an open source platform that allows one to create faster, easy to load, and high performing web apps.

#2 Augmented Reality and Virtual Reality Apps

Image result for augmented and virtual reality AR and VR apps have not created a log of buzz in 2016, but they got highly popular worldwide at the end. Augmented Reality is a technology that generates a composite view by imposing computer-generated images on user’s view of the real world. You can take the example of Pokemon Go. Another type of app that got popular in 2016 was Virtual Reality (VR) apps. These apps are a simulation of three-dimensional images that a person can interact with real-time using special electronic gadgets. Example Samsung gear, google cardboard, etc.

#3 Mobile Finance Service (MFS) Apps

Image result for mobile financial services paytm mobikwik Well, these are the easiest ones to understand. These apps have an exponential grow recently. Examples of MFS apps are PayTm, Mobiwiki, PayUmoney, etc. People prefer to use cashless transactions nowadays, and they are using mobile apps instead.

#4 Security Factor in Apps

Image result for mobile security apps There are millions of Android apps, and over 75 percent of them do not even pass security tests. These apps are easily accessible by the hackers. And Android app development companies are focusing on improving the security feature of the app. Also, many antivirus apps have come in the market like Avast, McAfee, AVG, 360 security, etc.
So, these are some of the major trends which are ruling the Android app development market in 2017. Apart from this, there are many wearable devices like Fitbit, Apple, Watch, etc.  that will rule the market.  

Swift 3.1: Swift Package Manager – Part 2

In last part of Swift 3.1 release, we discussed the major language changes, but Swift Package Manager was one of the most awaited updates. This update would have a major impact on your code as it has many new functionalities.

Image result for swift 3.1 Now, let us talk about why Swift Package Manager Updates was most awaited?

Every modern programming language has an official dependency management system. They come with an official solution for code distribution as an example RubyGems for Ruby, Composer for PHP, NPM for NodeJS, etc. But iOS used to be different, developers had to rely on third-party dependency management tools like CocoaPods and Carthage until Swift Package Manager came. Image result for swift 3.1  

Now Swift Package Manager is an official replacement for CocoaPods and Carthage. And you should be definitely using it in Swift project because-

  • It is an official package manager for Swift. It is considered to be a trusted source of the Swift packages.
  • CocoaPods and Carthage have Pros and Cons as they are managed by open-source communities, but SPM is managed by Apple. So there are fewer chances of having trouble, the developers don’t have to rely on open-source communities.
  • Though it is a major product and is still in development phase, but it will definitely grow. As it is the future, so you should consider using it as dependency manager.
  • Swift is a server side language, so SPM is expected to work on both Linux and macOS. There will be no restriction of using macOS to build and distribute Swift packages.

What is new?

1. Editable Packages

Swift 3.1 added editable packages concept in Swift Package Manager. It edits command by taking an existing package and converting it to an editable one. The editable package replaces all the canonical package’s occurrences in dependency graph. ‘–end-edit’ command can be used to revert the package manager back to canonical resolved package.

2. Version Pinning

Another amazing concept is added in Swift 3.1- version pinning package. The version pin command pins one or all dependencies like this-
$ swift package pin –all      // pins all the dependencies $ swift package pin Foo        // pins Foo at current resolved version $ swift package pin Foo –version 1.2.3  // pins Foo at 1.2.3
The developer can use the unpin command to revert to the previous package version with following commands-
$ swift package unpin —all $ swift package unpin Foo
The package manager stores the active version pin information from package.pins. If the file doesn’t exist, it creates an automatic file based on the requirements (as a part of automatic pinning process) specified in the package manifest. Image result for swift 3.1

3. Other Bits

The reset command of swift package resets a package back completely. There will be no dependencies checked out or built artifacts present after resetting them. And the swift test — parallel command executes tests in parallel.

4. Multiple Return Functions

The new package has disable the C functions which return twice such as vfork and setjmp. They change the control flow of the program. So the swift community is no longer supporting them, and using them results in compile-time error.

5. Disabled Auto-Linking

THE SPM has also disabled the auto-linking feature of module maps for C language targets-
  1. // Swift 3.0
  2. module MyCLib {
  3.    header “foo.h”
  4.    link “MyCLib”
  5.    export *
  6. }
  1. // Swift 3.1
  2. module MyCLib {
  3.    header “foo.h”
  4.    export *
  5. }

What next?

Swift 3.1 is a polished version of swift 3.0 with many new features. But as the technology changes and advances every single day, we can expect many more serious changes in Swift 4.0 later. These changes could include improvement in generics, regular expression, ergonomic string design, etc.

How Swift 3.1 is different from earlier version? – Part 1

As most of the developers know that Swift is a general-purpose programming language. It is built using a modern approach to safety, performance, and software design patterns. And if you are already an iOS developer, you are already familiar with these things! Recently, a beta version of Xcode 8.3 and Swift 3.1 was released with Swift Package Manager features and improvements to the language. In this article we will majorly discuss about the Language improvements, rest will be covered in other part of the article. Let us check out the most significant features and changes in Swift 3.1 as it will have a major impact on your code!

Introduction

Swift 3.1 has downward compatibility, a person can work on lower versions codes of Swift. All you need to do is to migrate your project to Swift 3.0 using Edit\Convert\To Current Swift Syntax in Xcode. Start Xcode, select File-> New-> Playground. Choose iOS as the platform, you can call it whatever you want, and save it wherever you want.

Language Improvements

There are a number of languages improvements in this release. It includes failable initializers for numeric types, new sequence functions, and more. Let us check them out-

1. Failable Numeric Conversion Initializers

The new version implements failable initializers for all numeric types such as Int, UInt, Float, Double, etc. It either completes successfully without losing any information or simply returns NIL. This feature helps while dealing with loosely typed data conversion from external sources in a safe and recoverable manner. Just check it out by processing this JSON code-
  1. class Student {
  2.  let name: String
  3.  let grade: Int
  4.  
  5.  init?(json: [String: Any]) {
  6.    guard let name = json[“name”] as? String,
  7.          let gradeString = json[“grade”] as? String,
  8.          let gradeDouble = Double(gradeString),
  9.          let grade = Int(exactly: gradeDouble)  // <– 3.1 feature here
  10.    else {
  11.        return nil
  12.    }
  13.    self.name = name
  14.    self.grade = grade
  15.  }
  16. }
  17. func makeStudents(with data: Data) -> [Student] {
  18.  guard let json = try? JSONSerialization.jsonObject(with: data, options: .allowFragments),
  19.        let jsonArray = json as? [[String: Any]] else {
  20.    return []
  21.  }
  22.  return jsonArray.flatMap(Student.init)
  23. }
 
  1. let rawStudents = “[{\”name\”:\”Ray\”, \”grade\”:\”5.0\”}, {\”name\”:\”Matt\”, \”grade\”:\”6\”},
  2.                    {\”name\”:\”Chris\”, \”grade\”:\”6.33\”}, {\”name\”:\”Cosmin\”, \”grade\”:\”7\”},
  3.                    {\”name\”:\”Steven\”, \”grade\”:\”7.5\”}]”
  4. let data = rawStudents.data(using: .utf8)!
  5. let students = makeStudents(with: data)
  6. dump(students) // [(name: “Ray”, grade: 5), (name: “Matt”, grade: 6), (name: “Cosmin”, grade: 7)]
Here, failable initializer is used to convert the grade property from Double to Int inside the Student class.
let grade = Int(exactly: gradeDouble)
If gradeDouble is a fractional value, it will fail. It will succeed only if the value can be represented exactly as an integer.

2. New Sequence Functions

There are two new functions for data filtering to the standard library’s Sequence protocol- prefix(while:) and drop(while:). Consider the Fibonacci infinite sequence:
  1. let fibonacci = sequence(state: (0, 1)) {
  2.  (state: inout (Int, Int)) -> Int? in
  3.  defer {state = (state.1, state.0 + state.1)}
  4.  return state.0
  5. }
  Swift 3.0 simply specify the iteration count to iterate through the Fibonacci sequence-
  1. // Swift 3.0
  2. for number in fibonacci.prefix(10) {
  3.  print(number)  // 0 1 1 2 3 5 8 13 21 34
  4. }
Swift 3.1 lets you use prefic(while:) and drop(while:) with a condition to get all the elements of the sequence between two given values.
  1. // Swift 3.1
  2. let interval = fibonacci.prefix(while: {$0 < 1000}).drop(while: {$0 < 100})
  3. for element in interval {
  4.  print(element) // 144 233 377 610 987
  5. }
In the code, prefix(while:) returns the longest sub-sequence which satisfies a certain predicate. while drop(while:) does the opposite.  

3. Concrete Constrained Extensions

Swift 3.1 extended generic type with a concrete type constraint. Previously, it could not extend a type like this due to protocol constraint. Example- Ruby on Rails provides isBlank method for checking for user input. Let us check out how it would be implemented in Swift 3.0 as a computed property on the String data type extension:
  1. // Swift 3.0
  2. extension String {
  3.  var isBlank: Bool {
  4.    return trimmingCharacters(in: .whitespaces).isEmpty
  5.  }
  6. }
  7. let abc = ” “
  8. let def = “x”
  9. abc.isBlank // true
  10. def.isBlank // false
If you want the isBlank computed property to work with optional strings as well, you would do the following in Swift 3.0:
  1. // Swift 3.0
  2. protocol StringProvider {
  3.  var string: String {get}
  4. }
  5. extension String: StringProvider {
  6.  var string: String {
  7.    return self
  8.  }
  9. }
  10. extension Optional where Wrapped: StringProvider {
  11.  var isBlank: Bool {
  12.    return self?.string.isBlank ?? true
  13.  }
  14. }
  15. let foo: String? = nil
  16. let bar: String? = ”  “
  17. let baz: String? = “x”
  18. foo.isBlank // true
  19. bar.isBlank // true
  20. baz.isBlank // false
Swift 3.1 lets you extend a concrete type instead of a protocol like this:
  1. // Swift 3.1
  2. extension Optional where Wrapped == String {
  3.  var isBlank: Bool {
  4.    return self?.isBlank ?? true
  5.  }
  6. }
It is better than earlier versions because it does the same work in fewer lines.

4. Nested Generics

The new version allows you to mix nested types with generics. Understanding it with an example would be easier when an article is posted on a website, the actual coding behind looks like this-
  1. class Team<T> {
  2.  enum TeamType {
  3.    case swift
  4.    case iOS
  5.    case macOS
  6.  }
  7.  
  8.  class BlogPost<T> {
  9.    enum BlogPostType {
  10.      case tutorial
  11.      case article
  12.    }
  13.    
  14.    let title: T
  15.    let type: BlogPostType
  16.    let category: TeamType
  17.    let publishDate: Date
  18.    
  19.    init(title: T, type: BlogPostType, category: TeamType, publishDate: Date) {
  20.      self.title = title
  21.      self.type = type
  22.      self.category = category
  23.      self.publishDate = publishDate
  24.    }
  25.  }
  26.  
  27.  let type: TeamType
  28.  let author: T
  29.  let teamLead: T
  30.  let blogPost: BlogPost<T>
  31.  
  32.  init(type: TeamType, author: T, teamLead: T, blogPost: BlogPost<T>) {
  33.    self.type = type
  34.    self.author = author
  35.    self.teamLead = teamLead
  36.    self.blogPost = blogPost
  37.  }
  38. }
  We nest BlogPost inner class within Team outer class and make both classes generic. And this is how it looks like-
  1. Team(type: .swift, author: “Cosmin Pupăză”, teamLead: “Ray Fix”,
  2.     blogPost: Team.BlogPost(title: “Pattern Matching”, type: .tutorial,
  3.     category: .swift, publishDate: Date()))
  4. Team(type: .swift, author: “Cosmin Pupăză”, teamLead: “Ray Fix”,
  5.     blogPost: Team.BlogPost(title: “What’s New in Swift 3.1?”, type: .article,
  6.     category: .swift, publishDate: Date()))
  Whereas it could be simplified. Nested inner type can inherit the parent’s class type by default if the nested inner type uses the generic outer one. Therefore you don’t have to declare it, like so:
  1. class Team<T> {
  2.  // original code
  3.  
  4.  class BlogPost {
  5.    // original code
  6.  }  
  7.  
  8.  // original code
  9.  let blogPost: BlogPost
  10.  
  11.  init(type: TeamType, author: T, teamLead: T, blogPost: BlogPost) {
  12.    // original code   
  13.  }
  14. }

5. Convert Non-Escaping Closures to Escaping Ones

In Swift 3.0, closure arguments were made non-escaping to function by default, while you can convert non-escaping closures to escaping ones temporarily by using withoutActuallyEscaping() helper function in Swift 3.1. Let us understand this with an example-
  1. func perform(_ f: () -> Void, simultaneouslyWith g: () -> Void,
  2.             on queue: DispatchQueue) {
  3.  withoutActuallyEscaping(f) { escapableF in     // 1
  4.    withoutActuallyEscaping(g) { escapableG in
  5.      queue.async(execute: escapableF)           // 2
  6.      queue.async(execute: escapableG)     
  7.      queue.sync(flags: .barrier) {}             // 3
  8.    }                                            // 4
  9.  }
  10. }
This function runs two closures simultaneously and then returns when both are done.
  1. f and g come in as non-escaping and are converted to escapableF and escapableG.
  2. async(execute:) calls require escaping closures. Fortunately, you have those because of the previous step.
  3. By running sync(flags: .barrier), you ensure that the async(execute:) methods are completely done and the closures won’t be called later on.
  4. Scope limits the use of escapableF and escapableG.
If you squirrel either temporary escaping closures away (i.e. actually escaped them) it would be a bug. There are many other changes in Swift 3.1. They include Swift Package Manager Updates, Multiple-Return Functions, Disable Auto-Linking, etc. We will be discussing it in next part. Till then share your views with use!  

5 Common Myths About Mobile App Development

The mobile application development industry is expanding, so are different myths about it. The industry has gone through many leaps and bounds recently. The reasons behind misconceptions could be half knowledge, hearsay, and past experience. While developing an application different problems and bugs come up which they are not obvious. People generally consider that these errors and bugs are similar, and this is what encourage myths. These misconceptions start from the sources or companies who could not get what they exactly want. They are generally old presumptions or because of out-of-date ideas which are not correct. And this why, the expansion of this industry has led to many misunderstandings relating to this line of business. In the following piece, we may be debunking a few of these myths:

Myth 1: In-house app development takes same time as the outsourced companies take

Image result for inhouse app development vs outsourcing Well, the reality is completely opposite. Developing an application yourself will take exactly 3-4 times the amount of minimum time you decided. Outsourcing the work would give you 90% results as there will be professionalism. Some companies decide to develop the app themselves to save money and time which ultimately turns out to be a bad idea.

Myth 2: Mobile app development is inexpensive

Image result for mobile app development is inexpensive Yes, the mobile apps are more compact in size than regular internet application, but it doesn’t make it less expensive. In fact, developing a mobile app need more expertise than any other app. The major cost needs to be sustained to employ or the expertise of a mobile application agency and getting software developed. The only already built thing available for free are the application quotes. Apart from this, the developers need to work it out themselves. So, the fact is mobile applications are not inexpensive.

Myth 3: Mobile apps develop their own demand

Image result for mobile app marketing Going by the facts and numbers, it is not as simple as it looks. A mobile application has to compete with many other similar applications. In order to come into the market, your marketing campaign needs to be strong enough to stand out from the competitors. Users just don’t rush into downloading applications on their phone as soon as they are released. So, you need to make sure that you marketing campaign attracts the users.

Myth 4: Building customised application demands a lot of programming

Image result for mobile app programming This myth has become everyone’s favourite, but let us come down to the reality. According to today’s scenario, most of the companies require minimum programming to build a solution. Companies need to accept the reality that company’s flexibility is more about the platform and incorporation than improvement, creation and release mobility solutions in a small fraction of the time and cost of standard solutions.

Myth 5: Facilities require huge investment

Image result for mobile app upgradation investment Though investment is required, but it is the poor planning of companies which lead to this myth. Most of the companies think that adding more servers is the solution to every problem. While you can easily provide a secure, scalable, and inexpensive solution with a cloud-based system. All you need to do is consult with an expert and make a well-planned financial strategy. These misconceptions have been flowing around the market which do not make sense. And if you are also dealing with it, you need to get out and find something better. These myths somehow degrade the quality of a mobile app, and it could be a huge disadvantage for the client and the developer as well.

Kotlin- The Next-Gen Android App Development Language

Android app development is a major part of today’s technical and economical world. People use different languages for developing apps, though Java remains the most used language to develop logic. While running a Java application, the app is compiled into a set of instructions called Bytecode and runs in a virtual machine. In last few years, new programming languages have been introduced which also run on Java virtual machine. The reason behind using these languages is that the resulting app looks same for the virtual machine with simple code and some fixes that developers face while coding in Java. Image result for kotlin   Recently, one such language is introduced by JetBrains, known for IntelliJ IDEA (Android Studio is based on IntelliJ), called Kotlin. It is a statically typed programming language that runs on the JVM. It can be compiled to JavaScript source code. It has many other amazing features, and we will be knowing about them in this article.

Why Kotlin instead of any other language?

Since Java is the only language most of the people use while developing the mobile apps, developers had no actual alternatives to Java app. Java comes with a lot of historical baggage and some issues. Java 8 solved some of those problems, and some were corrected in Java 10. But these two options also have loopholes. One of them is in order to use these two versions, one must have the minimum SDK to Android 24 to use Java 8 which is not an option for many developers. And Java 10 is even far from their reach. So, Kotlin was made to fill these gaps through model language. There are some core principles that Kotlin work with-
  1. Concise- Reduce amount of boilerplate code
  2. Safe- Avoid entire classes of error such as null pointer
  3. Smart- Make your code more readable and understandable
  4. Tool-friendly- One can choose any Java IDE or build from the command line
  5. Interoperable- Leverage existing frameworks and libraries of JVM, Android, and browser.

How to work on Kotlin?

Download the starter project. Extract and open the starter project in Android Studio. It is a simple app that allows users to search for books, book covers and share books with friends to explore Kotlin. Image result for kotlin vs java

It consist of three source code files, let us check it out-

MainActivity.java- an activity that displays the screen for searching and displaying a list of books. DetailActivity.java- an Activity that displays the book cover for the ID passed to it. JSONAdapter.java- a custom BaseAdapter that transforms a JSON object into a listview item. Build and run the project to see what you’re working with.

How to set up the environment of Kotlin?

Android Studio doesn’t have any idea of what to do with Kotlin. So the first thing you need to do is to install the Kotlin plugin and configure Kotlin in your project.

-Installing the Plugin

1. Go to Android Studio/ Preferences and Select the Plugins entry. kotlin for android 32. Click on Install JetBrains plugin on Plugins screen intro_to_kotlin_4 3. Search and select Kotlin from the list and click Install. intro_to_kotlin_5 4. When you are done with downloading and installing Kotlin, then you need to follow the prompts to restart the IDE. intro_to_kotlin_28

– Configure Kotlin in Project

Now the IDE knows what to do with Kotline, but your project app doesn’t, so you have to modify the project’s build configuration. How do modify the project’s build configuration? Let us check out- 1. Go to Tools-> Kotlin-> Configure Koltin in Project intro_to_kotlin_7 2. A Choose Configurator pop up will appear, select Android with Gradle from the drop down. intro_to_kotlin_8 3. On Configure Kotlin in Project popup, select the plugin version you want to use and click OK. Configure Kotlin in Project 4. These actions will make some changes to your build.gradle files.   build.gradle (Project: omg-android-starter): buildscript {  ext.kotlin_version = ‘1.0.3’ // 1  repositories {    jcenter()  }  dependencies {    classpath ‘com.android.tools.build:gradle:2.1.3′    classpath “org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version // 2    // NOTE: Do not place your application dependencies here; they belong    // in the individual module build.gradle files  } } allprojects {  repositories {    jcenter()  } } build.gradle (Module: OMG Android):    apply plugin: ‘com.android.application’ apply plugin: ‘kotlin-android’ // 3 android {    compileSdkVersion 23    buildToolsVersion “24.0.2”    defaultConfig {        minSdkVersion 14        targetSdkVersion 23    }  sourceSets {    main.java.srcDirs += ‘src/main/kotlin’ // 4  } } dependencies {  compile ‘com.android.support:appcompat-v7:23.2.0′  compile ‘com.loopj.android:android-async-http:1.4.4′  compile ‘com.squareup.picasso:picasso:2.1.1′  compile “org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version // 5 } repositories {  mavenCentral() }   Here is a summary of what this code is about-  
  1. Declares configured Kotlin version
  2. Declares classpath dependency artifact that contains the Kotlin Gradle plugin with the version declared earlier
  3. Specifies the use of Kotlin Android plugin via apply plugin command
  4. Defines that source files found in src/main/Kotlin will be compiled. Gradle will compile source Kotlin files found in src/main/java.
  5. Added the Kotlin Standard library as a compile-time dependency to the project.
