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

    }
}

private boolean whatsappInstalledOrNot(String uri) {
    PackageManager pm = getPackageManager();
    boolean app_installed = false;
    try {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        app_installed = true;

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (resultCode == Activity.RESULT_OK) {
        if (requestCode == PICK_IMAGE_CODE) {
            if (data != null) {
                val image = data.data
                val number = "9163********"
                    val whatsappIntent = Intent(Intent.ACTION_SEND)
                    whatsappIntent.setPackage("com.whatsapp")
                    whatsappIntent.setType("text/plain")
                    whatsappIntent.putExtra(
                        Intent.EXTRA_TEXT,
                        "I am sending the image for testing"
                    )
                    whatsappIntent.putExtra(Intent.EXTRA_STREAM, image)
                    whatsappIntent.setType("image/*")
                    whatsappIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
                    whatsappIntent.putExtra(
                        "jid",
                        PhoneNumberUtils.stripSeparators(number) + "@s.whatsapp.net"
                    ) //phone number without "+" prefix
                    startActivity(whatsappIntent)
                }
