Answer 1

Intent for opening a Telegram channel or user :

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("tg://resolve?domain=partsilicon"));
startActivity(intent);

Answer 2

First check if any telegram client (telegram messenger or telegram x) is installed. If not open it in browser.

fun telegramIntent(context: Context): Intent {
    var intent: Intent? = null
    try {
        try {
           context.packageManager.getPackageInfo("org.telegram.messenger", 0)//Check for Telegram Messenger App
        } catch (e : Exception){
           context.packageManager.getPackageInfo("org.thunderdog.challegram", 0)//Check for Telegram X App
        }
       intent = Intent(Intent.ACTION_VIEW, Uri.parse("tg://resolve?domain=${TELEGRAM_PAGE_ID}"))
    }catch (e : Exception){ //App not found open in browser
       intent = Intent(Intent.ACTION_VIEW, Uri.parse("http://www.telegram.me/$TELEGRAM_PAGE_ID"))
    }
   return intent!!
}
