I\'m planning to develop an android mobile application using android studio, where an user give email address and secret code. Then that secret code should be send to mentioned
If you use Intent.ACTION_SEND android show all communicatons app. If you want show only email client you can use the following code.
Intent mailIntent = new Intent(Intent.ACTION_VIEW);
Uri data = Uri.parse("mailto:?subject=" + "subject text"+ "&body=" + "body text " + "&to=" + "destination@mail.com");
mailIntent.setData(data);
startActivity(Intent.createChooser(mailIntent, "Send mail..."));
