send a whatsapp message automatically

Question

how to send a whatsapp message to a specific contact automatically?I have searched but it just opens the chat of that specific person but does not send the message automatically

Here is the code that am using:

private void openWhatsappContact(String number) {
    Uri uri = Uri.parse("smsto:" + number);
    Intent i = new Intent(Intent.ACTION_SENDTO, uri);
    i.setPackage("com.whatsapp");  
    startActivity(Intent.createChooser(i, ""));

I'm not sure you can send the message automatically, but try this to specify the message you want to send:

i.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
