Answer 1

I know this post is old but I encountered the same issue and I found the solution (in the official documentation):
As explained, Intent.EXTRA_EMAIL is:
A String[] holding e-mail addresses that should be delivered to.
So to fix your issue, instead of:
intent.putExtra(Intent.EXTRA_EMAIL,"receiver#gmail.com");
do:
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"receiver#gmail.com"});

This is how you correctly send an email via an intent. The URI arguments are required if not you will have problems getting Gmail to receive your emails.
Intent send = new Intent(Intent.ACTION_SENDTO);
String uriText = "mailto:" + Uri.encode("email#gmail.com") +
"?subject=" + Uri.encode("the subject") +
"&body=" + Uri.encode("the body of the message");
Uri uri = Uri.parse(uriText);
send.setData(uri);
startActivity(Intent.createChooser(send, "Send mail..."));

The disadvantage of doing it your way is that it gives gmail issues retrieving the address to send the mail to, and so many apps support message/rfc822so your user can get drowned in different clients. I advice you use
Intent sendMail = new Intent(Intent.ACTION_SENDTO);
String uriText = "mailto:" + Uri.encode("example#gmail.com") +
"?subject=" + Uri.encode("subject") +
"&body=" + Uri.encode("body);
Uri uri = Uri.parse(uriText);
sendMail.setData(uri);
startActivity(Intent.createChooser(sendMail, "Choose a client"));
as this is a bit more specific than specifying with intent.setType("message/rfc822"); and solves the issue with gmail. Good Luck.

For kotlin
The emial must be an arrayOf, nos just a string.
intent.putExtra(Intent.EXTRA_EMAIL, arrayOf("receiber#gmail.com"))
