How to get notified for send or cancel of an email

I am starting Email client using intent from my activity (Either native email or gmail). I just want to get notified into my activity when user presses send button or discards the email. I just want to start another activity when user press send button and want to show a dialog when user discards the email.

Here is my code

Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
    emailIntent.setType("message/rfc822");
    emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[] {"[email protected]"});
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Test Mail");
    emailIntent.putExtra(Intent.EXTRA_TEXT, "Test Mail Subject");
    startActivityForResult(emailIntent, REQ_CODE);


public void onActivityResult(int requestCode, int resultCode,
        Intent data) {

    if(requestCode == REQ_CODE){
        Toast.makeText(getApplicationContext(), "resultCode  "+resultCode, Toast.LENGTH_LONG).show();
        //if(resultCode == RESULT_OK){


        //}
    }
}

Thanks in Advance..

Solution

This is not possible. ACTION_SEND is not designed for use with startActivityForResult(), and nobody, let alone whatever email client the user happens to choose, is obligated to call setResult() to let you know what the user did.
