LocalDate is an immutable date-time object that represents a date, My data-objects were converted to have nullable-fields, but several kotlin-functions specified non-nullable arguments.A date without a time-zone in the ISO-8601 calendar system, In my case, android-studio generated code that would not compile. By default, an object is non-nullable and has to explicitly specified to be nullable. One of the big advantages kotlin has over java is the handling of nullability. Your project will probably not compile now, because of differences in how java and kotlin handles nullability. kt files in-place, leaving them in src/main/java. To convert all your java-code to kotlin-code.Īndroid studio will convert all your. Android studio will then try as best as it can To convert the existing javacode into kotlin, simply select the src/main/java folder in the project and chooseĬode->"Convert Java File to Kotlin File”. The first step is easy, android-studio will do most of the work for you.
Bugs in android-studio shows that it is still early days for kotlin-development on android.
