Expecting member declaration in Kotlin



I want to assign my class variable in constructor but I get an error expecting member declaration


class YLAService


var context:Context?=null

class YLAService constructor(context: Context)
this.context=context;// do something

In Kotlin you can use constructors like so:


class YLAService constructor(val context: Context)




Even shorter:


class YLAService(val context: Context)




If you want to do some processing first:


class YLAService(context: Context)

val locationService: LocationManager

init
locationService = context.getService(LocationManager::class.java)




If you really want to use a secondary constructor:


class YLAService

val context: Context

constructor(context: Context)
this.context = context





This looks more like the Java variant, but is more verbose.



See the Kotlin reference on constructors.





Thank you, But I Also do something inside constructor
