Send an email using intent in the sendEmail method, why does this work?

PS my english skill is bad and thanks for any answers.

Answer 1

 final Intent i = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto"," [e-mail] ", null)); i.putExtra(Intent.EXTRA_SUBJECT, "Emergency Location"); i.putExtra(Intent.EXTRA_TEXT,Html.fromHtml(DescribText));
