Send Email Via Gmail with Java Mail API in Android

Hi Guys!

Today I am sharing the code to send the email via gmail to any gmail user without interfere of any application with help of java mail API.
The JavaMail API provides a platform-independent and protocol-independent framework to build mail and messaging applications.

In our application we are going to use following things from JavaMail API:

• Multipart class: - it allow to device message into multipart so that long message can be sent easily.
• Session: - in order to send mail we need to create session between hosts.
• InternetAddress : it contains address , simply maid ID (example: abc@gmail.com).

For use of this you need to download the some jar file from Here.
1.  additional.jar
2. mail.jar
3. activation.jar

Download these jar file and make a java build path with your project.

Lets Start the coding to make a android project.

activity_main.xml

MainActivity.java

package com.sunil.sendmail;

import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import com.sunil.sendmail.R;

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Context;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity  implements OnClickListener{

 Session session=null;
 ProgressDialog pdialog=null;
 Context context=null;
 EditText reciept=null;
 EditText sub=null;
 EditText msg=null;
 String recpient=null;
 String subject=null;
 String textmessage=null;
 
   @Override
   protected void onCreate(Bundle savedInstanceState) {
   // TODO Auto-generated method stub
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);
      context=this;
   Button login = (Button) findViewById(R.id.mBtnSubmit);
   reciept=(EditText)findViewById(R.id.editText_to);
   sub = (EditText) findViewById(R.id.editText_sub);
   msg = (EditText) findViewById(R.id.editText_text);
   
   
   login.setOnClickListener(this); 

   
   }
   
  @Override
  public void onClick(View v) {
   
   recpient= reciept.getText().toString();
      subject= sub.getText().toString();
      textmessage= msg.getText().toString();
   
    Properties props = new Properties();
     props.put("mail.smtp.host", "smtp.gmail.com");
     props.put("mail.smtp.socketFactory.port", "465");
     props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
     props.put("mail.smtp.auth", "true");
     props.put("mail.smtp.port", "465");

     session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
                       protected PasswordAuthentication getPasswordAuthentication() {
     return new PasswordAuthentication("Your Gmail-ID", "Your Gmail_password");
     }
     });
     pdialog = ProgressDialog.show(context, "", "Sending Mail...",true);
     RetreiveFeedTask task= new RetreiveFeedTask();
     task.execute();
  }
  
   
   class RetreiveFeedTask extends AsyncTask {

     
    protected String doInBackground(String... urls) {
          try {
              
             Message message = new MimeMessage(session);
             message.setFrom(new InternetAddress("Your Gmail-ID"));
             message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recpient));
             message.setSubject(subject);
             message.setContent(textmessage, "text/html; charset=utf-8");

             Transport.send(message);
             
           
          } 
          catch (MessagingException e) {
            e.printStackTrace();
             }
          catch (Exception e) {
             e.printStackTrace();
            
          }
          return null;
      }

      protected void onPostExecute(String feed) {
       pdialog.dismiss();
       reciept.setText("");
       msg.setText("");
       sub.setText("");
       Toast.makeText(getApplicationContext(), "Message sent", Toast.LENGTH_LONG).show();
          
      }
   }


 }

Add the INTERNET permission in the AndroidManifest file .
  <uses-permission android:name="android.permission.INTERNET"/>
