如何解决如何使用Intent Android Studio打开WhatsApp或WhatsApp业务？

我正在使用此代码，它会打开WhatsApp，但不允许我打开WhatsApp业务，有什么办法可以验证用户安装了哪个WhatsApp？

String contact = phone;
Double amount_total = pac_val_amo + del_fac_amo;
String total = "S/. " + String.format("%.2f",amount_total);
String message = "Su pedido de " + store + " ha llegado,su pago total es de S/. " + total;
String url = "https://api.whatsapp.com/send?phone=" + contact + "&text=" + message;
try {
    PackageManager pm = getContext().getPackageManager();
    pm.getPackageInfo("com.whatsapp",PackageManager.GET_ACTIVITIES);
    Intent i = new Intent(Intent.ACTION_VIEW);
    i.setData(Uri.parse(url));
    startActivity(i);
    } catch (PackageManager.NameNotFoundException e) {
           Toast.makeText(getContext(),"WhatsApp is not installed on this Device.",Toast.LENGTH_SHORT).show();
    e.printstacktrace();
    }
