[Android] Call Kotlin's default argument method from Java

If you try to call a method with Kotlin's default arguments from Java, you will get an error.


Annotate @JvmOverloads

Sample code

Kotlin side

class Foo {
    @JvmOverloads fun bar(str: String = "A"): String {
        return str

Java side

Foo foo = new Foo();
foo.bar(); // "A"
foo.bar("B"); // "B"

@JvmOverloads Error when not annotating

java.lang.IllegalArgumentException: Parameter specified as non-null contains null
