Opening an email client on clicking a button

I am designing an app in which i need to open an email client on clicking a button. The email client should be opened with a pre-defined subject and 'to' address. Is there a way to attain this? Please provide me the solution and a code example if possible...

Goes like this:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "[email protected]" });
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, ""));

Alternatively, you could use IntentFactory.getSendEmailIntent(String mailTo, String mailCC, String subject, CharSequence body, File attachment).

To show only email clients use this code:

Intent intent = new Intent(Intent.ACTION_VIEW);
Uri data = Uri.parse("mailto:[email protected]?subject=" + Uri.encode(subject) + "&body=" + Uri.encode(body));
intent.setData(data);
startActivity(intent);

If you already chose default email client then it will launch it. Otherwise it will show a list of available email clients.

If you have a e-mail address on screen, you can just use in your xml, like this:

android:autoLink="email"

Ok - now the above answer no longer works for me in year 2020. I found something mentioned on google official developer sites which worked for me.

 Intent intent = new Intent(Intent.ACTION_SENDTO);
    intent.setData(Uri.parse("mailto:")); // only email apps should handle this
    intent.putExtra(Intent.EXTRA_EMAIL, addresses);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }

Prefer to use constants if available like for intent.type ClipDescription.MIMETYPE_TEXT_PLAIN

Kotlin:

val intent = Intent(Intent.ACTION_SEND)
intent.type = ClipDescription.MIMETYPE_TEXT_PLAIN
intent.putExtra(Intent.EXTRA_EMAIL, arrayOf("emailId 1", "emailId 2"))
intent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Subject for email")
intent.putExtra(android.content.Intent.EXTRA_TEXT, "Description for email")
startActivity(Intent.createChooser(intent,"Send Email"))

You can open email client on emulator by configuring your email address with email inbuild with email. Then when call the intent will open and send mail.
