send whatsapp message to specific number programmatically

Question

I'm developing an app, and I want to send a WhatsApp message to a specific number

I used this code from Satheesh's answer here and make corrections.
but the users who installed both WhatsApp messenger and business WhatsApp, this code send a message into business WhatsApp directly, it didn't show options to allow the users to choose between two apps

in android 5 it shows options but android 7 and 8 it didn't show options. it sends to business WhatsApp only.

can you help me to allow to give options to choose between both apps in android 7 and 8?

private void openWhatsApp (String phoneNumber) {

    boolean isWhatsappInstalled = whatsappInstalledOrNot("com.whatsapp");

    if (isWhatsappInstalled) {

        Intent intent = new Intent(Intent.ACTION_VIEW);

        intent.setData(Uri.parse("http://api.whatsapp.com/send?phone="+phoneNumber));

        startActivity(intent);

    } else {
        Uri uri = Uri.parse("market://details?id=com.whatsapp");
        Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
        Toast.makeText(getActivity(), "WhatsApp not Installed",
                Toast.LENGTH_SHORT).show();
        startActivity(goToMarket);
    }
}

private boolean whatsappInstalledOrNot(String uri) {
    PackageManager pm = getActivity().getPackageManager();
    boolean app_installed = false;
    try {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        app_installed = true;
    } catch (PackageManager.NameNotFoundException e) {
        app_installed = false;
    }
    return app_installed;
}

this will open your whatsapp message screen for that user whom you want to send the message and i think you can't send whatsapp message to user from any other app – Sandeep Malik Apr 16 '19 at 06:55
what is "jid"? here – Bhoomika Patel Apr 16 '19 at 06:58
this is oppening the whatsapp message screen of that person shom you want to chat – Sandeep Malik Apr 16 '19 at 07:01
