Is it possible to use a kotlin extension in a android java class? Example:
fun String.getSomething(): String {
return "something"
}
then in Java use it like:
String someString = "blabla";
someString.getSomething();
is this possible?

You can mix kotlin and java ( use/call kotlin classes in java classes ) But what you want here is use a kotlin feature in java - this is not possible

file.kt
:Then, in Java, you can call the static method from the corresponding file class:
