Just found this method in anko common package:

fun <T> AnkoAsyncContext<T>.onComplete(f: (T?) -> Unit) {
    val ref = weakRef.get()
    if (ContextHelper.mainThread == Thread.currentThread()) {
        f(ref)
    } else {
        <http://ContextHelper.handler.post|ContextHelper.handler.post> { f(ref) }
    }
}

I know that there is actually a try catch inside the method doAsync, should I use onComplete method like the finally method in try catch?
