I know that to open the maps is like this:
window.location = "geo:?q="+endereco;
To open the phone dial it looks like this:
window.location = "tel:"+telefone1;
To open the message screen (sms):
window.location = "sms:"+telefone;
Now, how do I open the email?
Chrome on Android is blocking redirects for applications that are not made through a user gesture.
So, via javascript it is not possible to redirect the user to the email application, this from Chrome 40, only if you put it for example on a href button, it will work when the user clicks the button.
Here's a discussion on the subject in the Chrome forum.
If you inspect the element you will see a message like
Navigation is blocked: mailto:? ...
You can try to do it this way, as I mentioned before it's adding a href.
var email = document.createElement('a');
email.style.visibility = 'hidden';
email.style.position = 'absolute';
email.href = 'mailto:[email protected]?subject=subject&body=body';
document.body.appendChild(email);
And after that when you're done you can do that.
email.click();
