 EditText textTo;
 EditText textSubject;
 EditText textMessage;
 
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
 
  buttonSend = (Button) findViewById(R.id.buttonSend);
  textTo = (EditText) findViewById(R.id.editTextTo);
  textSubject = (EditText) findViewById(R.id.editTextSubject);
  textMessage = (EditText) findViewById(R.id.editTextMessage);

     String to = textTo.getText().toString();
     String subject = textSubject.getText().toString();
     String message = textMessage.getText().toString();
 
     Intent email = new Intent(Intent.ACTION_SEND);
     email.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});
     //email.putExtra(Intent.EXTRA_CC, new String[]{ to});
     //email.putExtra(Intent.EXTRA_BCC, new String[]{to});
     email.putExtra(Intent.EXTRA_SUBJECT, subject);
     email.putExtra(Intent.EXTRA_TEXT, message);
 
     //need this to prompts email client only
     email.setType("message/rfc822");
 
     startActivity(Intent.createChooser(email, "Choose an Email client :"));
 
   }
  });
 }
}



See default scree, fill in the detail, and click on the “send” button.



It will prompts your existing Email client to select.



In this case, i selected Gmail, and all previous filled in detail will be populated to Gmail client automatically.



Note
Android does not provide API to send Email directly, you have to call the existing Email client to send Email.
