如何判断我的电子邮件是否已发送？

Question

I'm using the following code to send an email in my app.

public void sendEmail() {
    emailSent = 1;
    String to = toEmail.getText().toString();
    String subject = getUser() + " - User Feedback";
    String message = bodyTxt;

    Intent email = new Intent(Intent.ACTION_SEND);
    email.putExtra(Intent.EXTRA_EMAIL, new String[] { to });
    email.putExtra(Intent.EXTRA_SUBJECT, subject);
    email.putExtra(Intent.EXTRA_TEXT, message);

    email.setType("message/rfc822");
    try {
        startActivity(Intent.createChooser(email, "Send Email..."));
    } catch (android.content.ActivityNotFoundException ex) {
        String msg = ex.getMessage().toString();
        emailSent = 2;
        Toast.makeText(this, "There was a problem sending this email, please try again.", Toast.LENGTH_SHORT).show();
    } 
}

The email.setType() presents a screen offering options for which method to send the message including email. This works fine if the user selects email as a copy of the email comes up and the user can then send it. However, if the user doesn't do anything and simply uses the back space it returns to the app and assumes the email has been sent. How can I test for the user not sending the email?

You could startActivityForResult() and listen for a RESULT_OK in onActivityResults . But there is no framework requirement that forces the email app to setResult appropriately. So your mileage may vary based on the email client app.
