How to use Handler and handleMessage in Kotlin?

Question

Java code:

private final Handler mHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
       // code here
    }
};

How to convert this java code to Kotlin?

I tried this:

private val mHandler = object : Handler() {
    fun handleMessage(msg: Message) {
       // code here
    }
}

But this is seems to be incorrect and gives a compile time error on object

You may do it a bit easier (without WeakReference) by passing looper to handler:

val handler = object:  Handler(Looper.getMainLooper()) {
        override fun handleMessage(msg: Message) {
            doStuff()
        }
    }
