  emailIntent.setType("plain/text");

  emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
          new String[] { "[e-mail]" });

  emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
          "Email Subject");

  emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,
          "Email Body");

  startActivity(Intent.createChooser(
          emailIntent, "Send mail..."));

Look at the link, there is an answer for your question.

Sending Email in Android using JavaMail API without using the default/built-in app

回答2:

Referred link has correct answer, but there are written some libraries to make your work easy.

• https://github.com/yesidlazaro/GmailBackground
• https://github.com/thegenuinegourav/Android-Email-App-using-Javamail-Api
• https://github.com/prashantwosti/BackgroundMailLibrary

So don't write all code again, just use any of these library and get your work done in little time.

It might be an easiest way-

    String recipientList = mEditTextTo.getText().toString();
    String[] recipients = recipientList.split(",");

    String subject = mEditTextSubject.getText().toString();
    String message = mEditTextMessage.getText().toString();

    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.putExtra(Intent.EXTRA_EMAIL, recipients);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    intent.putExtra(Intent.EXTRA_TEXT, message);

    intent.setType("message/rfc822");
    startActivity(Intent.createChooser(intent, "Choose an email client"));
