I create a new AppName in Android Studio IDE and included Kotlin support. I like to know how to create a hello world in kotlin and run success.
Stop Asking such lame questions.
Here is your answer: https://github.com/abreslav/kotlin-android-hello
It’s really not nice to call a question lame and to provide an incorrect answer at the same time. Andrey’s project is 6 years old and does not use Gradle; it’s not possible to open it in Android Studio.
If I remember well when you create a new project from an empty activity AndroidStudio generate a functional Hello World application, you just have to press the green arrow on the top of the page to start the programm ( don’t forget to plug your phone and enable the debugger mode )
