• When you invent about Android App development,
  odds are one programming language instantly
  springs to mind Java.
•  
• While its valid that the greater part of Android
  applications is composed in Java, with regards
  to Android app development, Java isnt 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. Whats 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 youve heard great things about Kotlin and are
  occupied with attempting it for yourself, at that
  point youre 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.
  Its expressive, compact, and powerful. Best of
  all, its interoperable with our current Android
  languages and runtime. Google has officially
  announced Kotlin as a first class language for
  Android.

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 development until 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.

For what reason Should Kotlin be Android app
Developers 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 its their dedication. we can help
  you to build the best website and mobile app for

Line\n" "Third Line" Kotlin val text """
First Line Second Line Third Line
""".trimMargin()
Java String text x gt 5 ? "x gt 5" "x lt 5"
String message null log(message ! null ?
message "") Kotlin val text if (x gt 5) "x
gt 5" else "x lt 5" val message String? null
log(message ? "")
