Android : In android, How to send an email without user interaction, other than gmailsender, any yahoo mail or corporate mail like?

i am using the code snippet like below

class SendEmailAsyncTask extends AsyncTask { Mail m = new Mail("someone@gmail.com", "password");

        public SendEmailAsyncTask() {
            if (BuildConfig.DEBUG) Log.v(SendEmailAsyncTask.class.getName(), "SendEmailAsyncTask()");
            String[] toArr = {"someone@domain.com"};
            m.setTo(toArr);
            m.setFrom("someone@domain.com");
            m.setSubject("Email from Android");
            m.setBody("Got message");
        }

i wanna use someone@anydomain.com instead of someone@gmail.com also is there any way to avoid using the password there?
