In my app I send messages by using Whatsapp en E-mail. I use the Intent. Now I want to send messages with SMS in the same way: send the message to the sms app on my phone en send it from the sms app itself. I know how to send a SMS from within my app itself, but that is not the way I want to to it. How can I sent text to my SMS app in the same way I send text to my ahatsapp app?
