Android Send Email in Android Studio

In this post we will create an Android Email App.

We will not use the default Android Email Client to send emails instead we will use Javamail API to create our own email sender. And you can also use this App for Email.

So if you are searching Best Email App for Android then try the app created by yourself 😉

Before going through the tutorial you can check the following video to see exactly what you will be creating in this tutorial.

Download Javamail API for Android

• For this Android Email App we will use Javamail API, so before starting our android project download Javamail API from link given below

Javamail API Download (14368 downloads)

• You will get a zip file from the above link. Extract the zip and you will get three .jar files. We will use these .jar files in our android email app project.

Creating Android Email App in Android Studio

• Open Android Studio and create a new android project.
• First we will add the downloaded .jar’s to our project.
• From the left panel click on Android -> Project (see the image below)

android

• Now you will get the libs folder inside projectfolder -> app -> libs . Paste all the three .jar files which you have downloaded above inside the libs folder. (See the image below)

javamail api

• Now go to file -> project structure.

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"     android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"     android:paddingRight="@dimen/activity_horizontal_margin"     android:paddingTop="@dimen/activity_vertical_margin"     android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">       <TextView         android:text="Recipient Email"         android:layout_width="wrap_content"         android:layout_height="wrap_content" />     <EditText         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/editTextEmail" />     <TextView         android:text="Subject"         android:layout_width="wrap_content"         android:layout_height="wrap_content" />     <EditText         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/editTextSubject" />     <TextView         android:text="Message"         android:layout_width="wrap_content"         android:layout_height="wrap_content" />     <EditText         android:lines="4"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/editTextMessage" />     <Button         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/buttonSend"         android:text="Send"/> </LinearLayout>

• For this android email app we will use gmail to send emails. So create a new java class named Config.java and write the following code.

Config.java

Java

package net.simplifiedcoding.javamailexample;   /** * Created by Belal on 10/30/2015. */ public class Config {     public static final String EMAIL ="your-gmail-username";     public static final String PASSWORD ="your-gmail-password"; }

• You have to write your gmail username and password.
• Now create a new class SendMail.java. It will send our email. Write the following code in this class.

SendMail.java

Java

package net.simplifiedcoding.javamailexample;   import android.app.ProgressDialog; import android.content.Context; import android.os.AsyncTask; import android.widget.Toast;   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;   /** * Created by Belal on 10/30/2015. */   //Class is extending AsyncTask because this class is going to perform a networking operation public class SendMail extends AsyncTask<Void,Void,Void> {       //Declaring Variables     private Context context;     private Session session;       //Information to send email     private String email;     private String subject;     private String message;       //Progressdialog to show while sending email     private ProgressDialog progressDialog;       //Class Constructor     public SendMail(Context context, String email, String subject, String message){         //Initializing variables         this.context = context;         this.email = email;         this.subject = subject;         this.message = message;     }       @Override     protected void onPreExecute() {         super.onPreExecute();         //Showing progress dialog while sending email         progressDialog = ProgressDialog.show(context,"Sending message","Please wait...",false,false);     }       @Override     protected void onPostExecute(Void aVoid) {         super.onPostExecute(aVoid);         //Dismissing the progress dialog         progressDialog.dismiss();         //Showing a success message         Toast.makeText(context,"Message Sent",Toast.LENGTH_LONG).show();     }       @Override     protected Void doInBackground(Void... params) {         //Creating properties         Properties props = new Properties();           //Configuring properties for gmail         //If you are not using gmail you may need to change the values         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");           //Creating a new session         session = Session.getDefaultInstance(props,                 new javax.mail.Authenticator() {                     //Authenticating the password                     protected PasswordAuthentication getPasswordAuthentication() {                         return new PasswordAuthentication(Config.EMAIL, Config.PASSWORD);                     }                 });           try {             //Creating MimeMessage object             MimeMessage mm = new MimeMessage(session);               //Setting sender address             mm.setFrom(new InternetAddress(Config.EMAIL));             //Adding receiver             mm.addRecipient(Message.RecipientType.TO, new InternetAddress(email));             //Adding subject             mm.setSubject(subject);             //Adding message             mm.setText(message);               //Sending email             Transport.send(mm);           } catch (MessagingException e) {             e.printStackTrace();         }         return null;     } }

• Now come to MainActivity.java and write the following code.

MainActivity.java

Java

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58

package net.simplifiedcoding.javamailexample;   import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText;   import java.util.Properties;   import javax.mail.PasswordAuthentication; import javax.mail.Session;   public class MainActivity extends AppCompatActivity implements View.OnClickListener {       //Declaring EditText     private EditText editTextEmail;     private EditText editTextSubject;     private EditText editTextMessage;       //Send button     private Button buttonSend;       @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);           //Initializing the views         editTextEmail = (EditText) findViewById(R.id.editTextEmail);         editTextSubject = (EditText) findViewById(R.id.editTextSubject);         editTextMessage = (EditText) findViewById(R.id.editTextMessage);           buttonSend = (Button) findViewById(R.id.buttonSend);           //Adding click listener         buttonSend.setOnClickListener(this);     }         private void sendEmail() {         //Getting content for email         String email = editTextEmail.getText().toString().trim();         String subject = editTextSubject.getText().toString().trim();         String message = editTextMessage.getText().toString().trim();                  //Creating SendMail object         SendMail sm = new SendMail(this, email, subject, message);                  //Executing sendmail to send email         sm.execute();     }       @Override     public void onClick(View v) {         sendEmail();     } }

• Finally add internet permission to manifest.

Internet Permission

1	<uses-permission android:name="android.permission.INTERNET"/>

• Thats it now run your application.
