title: How to send an email without the button "send" clicked twice?
body: <p>I like to send an email using the user app installed on the phone, in this way:
  In my app, the user click on a "send" button, that then open the user email client app (Gmail, or Kmail, etc...). And then, to send the email, the user will click on the app "send" button. Here are the "send" two clicks (my app + email client app)!! I don't like.</p>
  
  <p>I want that when the user click my app "send" button and then choose the system email client to be used, the mail is sent without another click to the system email client send button: this should be done automatically!</p>
  
  <p>Is there a way? How?</p>
