How to properly create an Intent to refer like Tez?

In my app i have to add an intent to share my app. I looked through Tez, which shares the app icon along with a text which contains a hyperlink. How to achieve this?

private void prepareShareIntent(Bitmap bmp) {
        Uri bmpUri = getLocalBitmapUri(bmp); // see previous remote images section
        // Construct share intent as described above based on bitmap

        Intent shareIntent = new Intent();
        shareIntent = new Intent();
        shareIntent.setPackage("com.whatsapp");
        shareIntent.setAction(Intent.ACTION_SEND);

        shareIntent.putExtra(Intent.EXTRA_TEXT, getResources().getString(R.string.share_app)  );
        shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
        shareIntent.setType("image/*");
        shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        startActivity(Intent.createChooser(shareIntent, "Share Opportunity"));

    }

private Uri getLocalBitmapUri(Bitmap bmp) {
        Uri bmpUri = null;
        File file = new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
        FileOutputStream out = null;
        try {
            out = new FileOutputStream(file);
            bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
            try {
                out.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
            bmpUri = Uri.fromFile(file);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        return bmpUri;
    }
