  1. Kotlin – Modern Multi platform Android App Development Mobile App Development Services

  2. When you invent about Android App development, odds are one programming language instantly springs to mind: Java. • While it’s valid that the greater part of Android applications is composed in Java, with regards to Android app development, Java isn’t your solitary choice. • You can compose Android applications in any language that can assemble and keep running on the Java Virtual Machine (JVM), and your end clients will be unaware. What’s more, one JVM-good programming language that is truly taken the eye of the Android association is Kotlin, a statically written programming language from JetBrains. • If you’ve heard great things about Kotlin and are occupied with attempting it for yourself, at that point you’re in the correct place. In this three-section arrangement, I will share all that you have to know so as to begin utilizing Kotlin for Android development. • Kotlin is now an official language on Android. It’s expressive, compact, and powerful. Best of all, it’s interoperable with our current Android languages and runtime. Google has officially announced Kotlin as a first class language for Android.

  3. Modern. Expressive. Safe. • It contains security features for null ability and immutability, to make your Android apps strong and performant by default. • Kotlin is the first of its kind statically wrote programming language that can be utilized for building current multi-stage applications. • Java has been the essential language for Android app developmentuntil the point when Kotlin appeared. After the coming of Kotlin, it is out of line to state ‘Java is the main or rather the best decision for development’.

  4. For what reason Should ‘Kotlin’ be Android app Developer’s Choice? • Designers who have officially changed from Java to Kotlin to program applications would know how it is superior to Java. Kotlin app development has risen as a developing selection of organizations needing to construct one of a kind applications. Created by JetBrains, this programming language is even-minded and compact, which makes coding a fantastic affair for designers. • Our hire dedicated programmers loved to build the best apps and it’s their dedication. we can help you to build the best website and mobile app for Android and iPhone. we are providing the best web application at affordable prices. Our hire Android Apps Developersare experts in standard software technologies and utilize many different development tools to design productive and user-friendly Android applications for Android smartphones and tablets.

  5. Given underneath are an arrangement of highlights that clarify why designers ought to settle on Kotlin: • Java Interoperability • Familiar Syntax • Less Coding • Ease of Learning • Concise Coding • Safety • Free to Use • Tool-friendly

  6. What Java has that Kotlin does not • Checked exceptions • Primitive types that are not classes • Static members • Non-private fields • Wildcard-types

  7. What Kotlin has that Java does not • Lambda expressions + Inline functions = performant custom control structures • Extension functions • Null-safety • Smart casts • String templates • Properties • Primary constructors • First-class delegation • Type inference for variable and property types • Singletons • Declaration-site variance & Type projections • Range expressions • Operator overloading • Companion objects • Data classes • Separate interfaces for read-only and mutable collections

  8. From Java To Kotlin – Your Cheat Sheet For • Print to Console • Constants and Variables Java String name ="Amit Shekhar"; finalString name ="Amit Shekhar"; Kotlin varname="Amit Shekhar" valname="Amit Shekhar" Java System.out.print("Amit Shekhar"); System.out.println("Amit Shekhar"); Kotlin print("Amit Shekhar") println("Amit Shekhar")

  9. From Java To Kotlin – Your Cheat Sheet For • Print to Console • Constants and Variables Java String name ="Amit Shekhar"; finalString name ="Amit Shekhar"; Kotlin varname="Amit Shekhar" valname="Amit Shekhar" Java System.out.print("Amit Shekhar"); System.out.println("Amit Shekhar"); Kotlin print("Amit Shekhar") println("Amit Shekhar")

  10. From Java To Kotlin – Your Cheat Sheet For • Assigning the null value • Concatenation of strings Java String otherName; otherName =null; Kotlin varotherName:String? otherName =null Java String firstName ="Amit"; String lastName ="Shekhar"; String message ="My name is: "+ firstName +" “+ lastName; Kotlin valfirstName="Amit" vallastName="Shekhar" valmessage="My name is: $firstName $lastName"

  11. From Java To Kotlin – Your Cheat Sheet For • New line in a string • Ternary Operations Java String text ="First Line\n"+"Second Line\n"+"Third Line"; Kotlin valtext="""|First Line|Second Line|Third Line""".trimMargin() Java String text = x >5?"x > 5":"x <= 5"; String message =null; log(message !=null? message :""); Kotlin valtext=if (x >5) "x > 5" else"x <= 5" valmessage:String? =null log(message ?:"")

  12. From Java To Kotlin – Your Cheat Sheet For • Logical Operators Java finalint andResult = a & b; finalint orResult = a | b; finalint xorResult = a ^ b; finalint rightShift = a >>2; finalint leftShift = a <<2; finalint unsignedRightShift = a >>>2; Kotlin valandResult= a and b valorResult= a or b valxorResult= a xor b valrightShift= a shr 2 valleftShift= a shl 2 valunsignedRightShift= a ushr 2

  13. From Java To Kotlin – Your Cheat Sheet For • Check the type and casting • Multiple conditions Java if (object instanceofCar) { } Car car = (Car) object; Kotlin if (object is Car) { } varcar=objectasCar// if object is nullvarcar=objectas? Car// var car = object as Car? Java if (score >=0&& score <=300) { } Kotlin if (score in0..300) { }

  14. From Java To Kotlin – Your Cheat Sheet For • Splitting arrays • Defining methods Java String[] splits ="param=car".split("="); String param = splits[0]; String value = splits[1]; Kotlin val (param, value) ="param=car".split("=") Java void doSomething() { // logic here } Kotlin fundoSomething() { // logic here }
