Why would you ever write the original Java code instead of String str = "";? — Alexey Romanov

If you are creating a string literal (e.g. you don't need create a string from an existing byte[] or char[]), do not use a constructor to create the String and instead use the literal syntax instead. Using String literals will prevent unnecessary allocation from occurring by allowing the String to be interned (see docs.oracle.com/javase/specs/jls/se7/html/jls-3.html#jls-3.10.5) — whaley

So private val mEmailApi : String("") you just define type of your field mEmailApi. But calling constructor during type declaration impossible.

And so: private val mEmailApi = "" you initialize it.

If you initialize your filed during to define, you need not to define type obviously.
