How do I open conversation of a particular contact in Whatsapp

Question

I want to send a message using whatsapp only to a particular contact without the user having to select it from his contact list. I am using the below code to fire an intent

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(sendIntent);

But this opens the whatsapp contact screen from which the user has to select the contact name.

Try the below code.

try {
   String num= "+918888888888"; // contains spaces.
            num= num.replace("+", "").replace(" ", "");

            Intent sendIntent = new Intent("android.intent.action.MAIN");
            sendIntent.putExtra("jid", num+ "@s.whatsapp.net");
            sendIntent.putExtra(Intent.EXTRA_TEXT, "Test");
            sendIntent.setAction(Intent.ACTION_SEND);
            sendIntent.setPackage("com.whatsapp");
            sendIntent.setType("text/plain");
            startActivity(sendIntent);
} catch (Exception e) {
   app.showSnackBar(parentView, "Whatsapp have not been installed.");
}

Is this sending text without selecting to that chat number ? Its only opening the chat history not sending message – N J Feb 09 '16 at 05:09
This will just open the contact with previous conversation but sms_body is empty not set to editText in whtasapp. – Suhas Bachewar Feb 09 '16 at 05:10
