Answer 1

Your initial problem is that the mime type is incorrect, it should be text/plain, not plain/text. However, this creates more of a generic share Intent that will match all kinds of apps from SMS to Dropbox. If you are truly only wanting to limit the user's options to email clients, you should set up the Intent with a different type like so:

Intent messageIntent = new Intent();
messageIntent.setAction(Intent.ACTION_SEND);
messageIntent.setType(“message/rfc822”);

Finally, more of a side note, since you are asking an external application to handle this action for you, good practice also dictates that your application should catch the ActivityNotFoundException and notify the user of this for cases where the user actually doesn't have an app on their device that will handle this request.

Answer 2

This is how to have the user send an email:

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "YOUR SUBJECT");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, "email@domain.com");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Default email text");
startActivity(Intent.createChooser(emailIntent, "Send email via:"));
