Hey peeps, no idea if this is the correct location to ask, but I have a question regarding creating a Universal Remote Control application in android for android TV. I'm wondering if there is some native API or SDK to implement which can handle the connection and can send certain keycodes to androidTV. I have made an SO post as well, so instead of typing it all here again, please check it out at

. Any thoughts would be helpful and very much obliged!!

It's the wrong location to ask😂

Try stackoverflow

Hello I have this extension to apply the styles on the targeted words, but it doesn't work applying the styles if I send multiple words fro some reason, I tested in a sample project and it works fine .. anyone could help me with it.

fun String.applySpans(vararg pairs: Pair<String, Any>): Spannable {
    val spannable = SpannableStringBuilder(this)
    pairs.forEach {
        val start = this.indexOf(it.first)
        val end = start + it.first.length
        spannable.setSpan(it.second, start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE)
    }
    return spannable
}

this is the working version in the test sample

val bold = StyleSpan(Typeface.BOLD)
        val italic = StyleSpan(Typeface.BOLD_ITALIC)

        val string = getString(R.string.hello_message, "John", "Wick")

        testTextView.text = string.applySpans(
                "John" to bold,
                "Wick" to italic
        )

this is the code with the problem

is AlternateSearchError.NotDeliveringToArea -> {
                searchErrorView.errorAction.visible()
                val message = getString(R.string.not_delivery_to_this_area, searchError.restaurant, searchError.area)
                searchErrorView.errorMessage.text = message.applySpans(
                        searchError.restaurant to bold,
                        searchError.area to bold
                )
            }

Hello guys, currently we are introducing AAC into our project, mainly, viewmodels and navigation. It seemed like a good idea but now we are questioning it. We have several custom views with isolated logic, now we are trying to introduce the viewmodels and subscribing properly. We have something like: Activity -> Fragment -> Custom view with it's own viewModel. Questions, how can we properly subscribe our viewmodels within the custom view to the proper lifecycleowner, in this case always a fragment? Is there any misconception on our side? Are we supposed to have huge fragments? or to isolate logic within view+viewmodel bundles? Kind regards!

divide by 0

yes. I know that TODO() crashes the app, thought there could be something more

throw an exception? As far as I know, there is not anything like fatalError() in Swift

ok. enough errors. thanks

lol

Hello everybody, Im newbie in Kotlin So Why do we need to add

run

block to wrap some logical code ? Thanks

compositeDisposable.add(
            repo.getAll()
                .subscribeOn(<http://schedulerProvider.io|schedulerProvider.io>())
                .observeOn(schedulerProvider.ui())
                .subscribe({ data ->
                    run {
                        output?.onResultCategories(BlockToday(TodayType.CATEGORIES, data.data))
                    }
                }, { throwable ->
                    run {
                      throwable.printStackTrace()
                    }
                })

@Sam could you paste the code as text, or expand it a bit and remove the blocking icons and popup text ? THe visible code is not inclusive so its hard to tell if something's hidden or truncated or what

@DALDEI: I have updated my mess. Thanks.

One doesnt need to use 'run' -- any more then any other library function (run is not a builtin keyword its 'just a function') There are many cases where one might want to use 'run' or where something of similar semantics is needed . 'run' is a function with a 'receiver' , unlike a basic expression or a bare {} lambda. This allows it to be used in places where basic expressions or statements are not allowed or require 'wrapping' (such as with run!) You cannot do this: ('if' does not accept a receiver)

"hi".if( this == "bye" ) println( "BYE" ) else println( this )

But you can do this

"hi".run {

if( this == "bye" ) println( "BYE" ) else println( this )

}

Another common use case for run is as the body of a function that is more then 1 expressions so you can 'avoid' using return ..

fun  printAndAdd( a: Int )  : Int {

println(a)

return a+1

}

vs

fun printAndAdd( a: Int ) = run {

println(a)

a+1

}

Note: the later case allows the compiler to infer the return type as well as eliminate the return statement fairly minor difference in the above case but can be more useful as the body gets more complex.

@Sam re your (fixed) code I see no reason run is required in either statement Maybe I am missing something

@DALDEI: thanks. I got it :)))

Hi there!, I'm investigating about Kotlin Cinterop, do you know if you can use this feature to call a c library in Android?

I have been reading the documentation but it is not very clear, and it is usually targeted to linux/osx desktop
