I use this code its working perfectly for me. And also i am checking if whats-app not install go to play store.

private void openWhatsApp() {
    String smsNumber = "8801714884544";
    boolean isWhatsappInstalled = whatsappInstalledOrNot("com.whatsapp");
    if (isWhatsappInstalled) {
        try {
            Intent sendIntent = new Intent("android.intent.action.MAIN");
            sendIntent.setAction(Intent.ACTION_SEND);
            sendIntent.setType("text/plain");
            sendIntent.putExtra(Intent.EXTRA_TEXT, FormViews.getTexBoxFieldValue(enquiryEditText));
            sendIntent.putExtra("jid", smsNumber + "@s.whatsapp.net"); //phone number without "+" prefix
            sendIntent.setPackage("com.whatsapp");
            startActivity(sendIntent);
        } catch(Exception e) {
            Toast.makeText(getActivity(), "Error/n" + e.toString(), Toast.LENGTH_SHORT).show();
        }
    } 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();
        getActivity().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;
}
