How to send an email without the button "send" clicked twice?

I like to send an email using the user app installed开发者_高级运维 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.

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!

Is there a way? How?

There is no way to send an email using one of the built in clients without the user also clicking send in the email program. If this were possible you could write an app that silently sent emails from users email accounts.

Yup there is a way that worked fine for me. It uses the JavaMail port
