I am starting to work in Kotlin and I need to parse a hex String to a long, which in java can be done with
Long.parseLong("ED05265A", 16); I can not find anything this in Kotlin, although I can find
val i = "2".toLong() This is not what I am looking for!
before I write anything from scratch is there a built in function for this?

toLongOrNull() to convert the string to a Long , return a null if the string is not a valid representation of a Long.
To convert hex string to byte array, you need to first get the length of the given string and include it while creating a new byte array. byte[] val = new byte[str. length() / 2]; Now, take a for loop until the length of the byte array.
Since Kotlin v1.1 you can use:
"ED05265A".toLong(radix = 16) Until then use the Java's Long.parseLong.
