apps for mobile, web, and desktop using a unified codebase.
Popular IDE's for Android Development:
• Android Studio
• Visual Studio
• Eclipse

• Productivity and Satisfaction: Kotlin is used by over
60% of professional Android developers. It helps
boost productivity, developer satisfaction, and code
safety.
• Expressive and Concise: Kotlin’s modern language
features allow developers to focus on expressing their
ideas and write less boilerplate code.
• Safer Code: With nullability included in its type system,
Kotlin helps avoid NullPointerExceptions. Android apps
that use Kotlin are 20% less likely to crash.
