This is a simple solution, but it works flawlessly.

try {
    Intent telegram = new Intent(Intent.ACTION_VIEW, Uri.parse("https://t.me/UsernameOrId"));
    telegram.setPackage("org.telegram.messenger");
    startActivity(telegram);
} catch (Exception e) {
    Toast.makeText(this, "Telegram app is not installed", Toast.LENGTH_LONG).show();
}

This one worked for me:

try {
Intent telegram = new Intent(Intent.ACTION_VIEW, Uri.parse("https://t.me/USER_NAME"));
 telegram.setPackage("org.telegram.messenger");
 startActivity(telegram);
}catch (Exception e) 
{
   Toast.makeText(getContext(), "Telegram app is not installed", Toast.LENGTH_LONG).show();
 }

Tip: You can get USER_NAME by click on you telegram profile option you will get option of username in Account session --> if username is none create unique username and put here its work for me

How it works:

  • It builds list of browsers to ignore them if telegram client is installed.

  • If there is one and only one client(goodresolvers == 1) then it's opened.

  • If there are no good clients (goodresolvers == 0) it fall backs to default intent handler.

  • You can improve this code further if you implement a dialog with custom chooser who only allows selecting "good" clients in case user have several Telegram clients installed.

        public static void openTelegram(Activity activity, String userName) {
            Intent general = new Intent(Intent.ACTION_VIEW, Uri.parse("https://t.com/" + userName));
            HashSet<String> generalResolvers = new HashSet<>();
            List<ResolveInfo> generalResolveInfo = activity.getPackageManager().queryIntentActivities(general, 0);
            for (ResolveInfo info : generalResolveInfo) {
                if (info.activityInfo.packageName != null) {
                    generalResolvers.add(info.activityInfo.packageName);
                }
            }
    
            Intent telegram = new Intent(Intent.ACTION_VIEW, Uri.parse("https://t.me/" + userName));
            int goodResolver = 0;
            // gets the list of intents that can be loaded.
            List<ResolveInfo> resInfo = activity.getPackageManager().queryIntentActivities(telegram, 0);
            if (!resInfo.isEmpty()) {
                for (ResolveInfo info : resInfo) {
                    if (info.activityInfo.packageName != null && !generalResolvers.contains(info.activityInfo.packageName)) {
                        goodResolver++;
                        telegram.setPackage(info.activityInfo.packageName);
                    }
                }
            }
            //TODO: if there are several good resolvers create custom chooser
            if (goodResolver != 1) {
                telegram.setPackage(null);
            }
            if (telegram.resolveActivity(activity.getPackageManager()) != null) {
                activity.startActivity(telegram);
            }
        }

usage: openTelegram(activity, "userTest");
