b4aKotlin

Demonstrate interaction between B4A and Kotlin

Build the Kotlin Jar

kotlinc example.kt -include-runtime -d h:\master\lib\example.jar
kotlinc example.kt -include-runtime -d h:\master\project\lib\example.jar

Build the B4A Wrapper:

../SimpleLibraryCompiler.exe Library_Name h:\master\project  - Tool

Example use of Kotlin function using B4A

Sub Globals
	Dim At() As Int
	At = Array As Int(5, 7, 1, 4, 9, 2, 1, -1)
End Sub

Sub Activity_Create(FirstTime As Boolean)
	Dim kt As Kotlin
	Log(kt.randomnumber(1,10))
	Log(kt.summ(At))
End Sub
 

Advancing

Building a more advanced jar that requires third part jars can be compiled in this way

kotlinc hello.kt -cp thirdparty.jar -include-runtime -d kotlin.jar
