Handle expired links while parsing JSON from within the android application

Question

I am designing an application in Kotlin which parses json-array. I have completed the application successfully but I was stuck on one minor(in my case major) glitch.I have successfully parsed the array and displayed the required array of objects in CardView and also opened the link in the browser when the card item is clicked.

Problem

The JSON contains certain links which are expired or are no longer in use. How do I handle such(expired) links from within the app when the user clicks on that particular card(with any flowery message or `ImageView)? I am comfortable in Android basics and still learning to devise Kotlin in android application and searched on the internet to the best of my knowledge but all my efforts went in vein.

Any help is warmly and benignly welcomed....

Below is my Code fragment(FeedViewHolder.kt):

class FeedViewHolder(itemView: View):RecyclerView.ViewHolder(itemView), View.OnClickListener,View.OnLongClickListener {

var txtTitle: TextView
var txtPubdate: TextView
var txtContent: TextView

private var itemClickListener: ItemClickListener? = null

init {
    txtTitle = itemView.findViewById(R.id.txtTitle) as TextView
    txtPubdate = itemView.findViewById(R.id.txtPubdate) as TextView
    txtContent = itemView.findViewById(R.id.txtContent) as TextView

    itemView.setOnClickListener(this)
    itemView.setOnLongClickListener(this)

}

fun setItemClickListener(itemClickListener: ItemClickListener) {
    this.itemClickListener = itemClickListener
}

override fun onClick(v: View?) {
    itemClickListener!!.onClick(v, adapterPosition, false)
}

override fun onLongClick(v: View?): Boolean {
    itemClickListener!!.onClick(v, adapterPosition, true)
    return true
}
}

Adapter Class

class FeedAdapter(private val rssObject: RSSObject, private  val 
 mContext:Context): RecyclerView.Adapter<FeedViewHolder>()
{
private val inflater:LayoutInflater

init {
    inflater = LayoutInflater.from(mContext)
}
override fun getItemCount(): Int {
    return rssObject.items.size
}

override fun onBindViewHolder(holder: FeedViewHolder, position: Int) {

    holder.txtTitle.text = rssObject.items[position].title
    holder.txtContent.text = rssObject.items[position].Content
    holder.txtPubdate.text = rssObject.items[position].pubDate

    holder.setItemClickListener(ItemClickListener { view, position, isLongClick ->

        if(!isLongClick){

            val browserIntent = Intent(Intent.ACTION_VIEW, Uri.parse(rssObject.items[position].link))
            browserIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
            mContext.startActivity(browserIntent)
        }

    })
}

override fun onCreateViewHolder(parent: ViewGroup?, viewType: Int): FeedViewHolder {
val itemView = inflater.inflate(R.layout.row,parent,false)
    return FeedViewHolder(itemView)
}
