To send email in Android we can use Intent.ACTION_SENDTO to call existing email app.

Have a look at below code snippet for Implementation

Source Code:

        Intent intent = new Intent(Intent.ACTION_SENDTO);
        intent.setData(Uri.parse("mailto:"));   // only Email apps will handle this
        intent.putExtra(Intent.EXTRA_EMAIL, addresses);
        intent.putExtra(Intent.EXTRA_SUBJECT, subject);
