I have created one contact us activity in my android application. It contain 4 edit text such as name, phone number, email and message along with the submit button. What i have to do is when i will click on submit button then the data from all four edit text should be E-mailed to me on my mail id. Can anyone suggest how can i do so? If any further details are required then please let me know. Thanks Here is some code sample.

                String Name = name.getText().toString();
                String Phone = phone.getText().toString();
                String Email = email.getText().toString();
                String Message = message.getText().toString();

                //check whether the msg empty or not
                if (Name.length() != 0 && Phone.length() != 0 && Email.length() != 0) {
                    HttpClient httpclient = new DefaultHttpClient();
                    HttpPost httppost = new HttpPost("http://www.abcd.com/Server1.php");

                    try {
                        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                        nameValuePairs.add(new BasicNameValuePair("id", "01"));
                        nameValuePairs.add(new BasicNameValuePair("message", Name));

                        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                        httpclient.execute(httppost);
                        name.setText(""); //reset the message text field
                        phone.setText(""); //reset the message text field
                        email.setText(""); //reset the message text field
                        message.setText(""); //reset the message text field
                        Toast.makeText(getBaseContext(), "Sent", Toast.LENGTH_SHORT).show();
                    } catch (ClientProtocolException e) {
                        e.printStackTrace();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                } else {
                    //display message if text field is empty
                    Toast.makeText(getBaseContext(), "All fields are required", Toast.LENGTH_SHORT).show();
                }
            }

Here you can find a solution for sending email with intent (user action required).

You have to create a String with email body containing all data you want to send, then the Email client is opened and the user can manually send the message.

Otherwise you can use your smtp configuration sending an email in background, without user action as explained here. This way the email is sent without user knowledge, but you have to know configuration of your Email account.

Following for Gmail (copied from here):
