In this article, you will make a basic Android Application that can be used to send email through your android application. You can do so with the help of Intent with action as ACTION_SEND with extra fields:

  • email id to which you want to send mail,
  • the subject of the email and
  • body of the email.

Basically Intent is a simple message object that is used to communicate between android components such as activities, content providers, broadcast receivers, and services, here use to send the email. This application basically contains one activity with EditText to take input of email address, subject, and body of the email from the user and button to send that email.

Step by Step Implementation

Step 1: Create a New Project in Android Studio

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. The code for that has been given in both Java and Kotlin Programming Language for Android.

Step 2: Working with the XML Files

Next, go to the activity_main.xml file, which represents the UI of the project. Below is the code for the activity_main.xml file. Comments are added inside the code to understand the code in more detail. This file contains a Relative Layout which contains three Edit texts for receiver mail id, another for the subject of the mail, and last one for the body of the email, and three TextViews for the label and a button for starting intent or sending mail: 

XML




<?xml version="1.0" encoding="utf-8"?>
<!-- Relative Layout -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
  
    <!-- Edit text for email id -->
    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentRight="true"
        android:layout_marginTop="18dp"
        android:layout_marginRight="22dp" />
  
    <!-- Edit text for email subject -->
    <EditText
        android:id="@+id/editText2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText1"
        android:layout_alignLeft="@+id/editText1"
        android:layout_marginTop="20dp" />
  
    <!-- Edit text for email body -->
    <EditText
        android:id="@+id/editText3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText2"
        android:layout_alignLeft="@+id/editText2"
        android:layout_marginTop="30dp" />
  
    <!-- text Views for label -->
    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/editText1"
        android:layout_alignBottom="@+id/editText1"
        android:layout_alignParentLeft="true"
        android:text="Send To:"
        android:textColor="#0F9D58" />
  
    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/editText2"
        android:layout_alignBottom="@+id/editText2"
        android:layout_alignParentLeft="true"
        android:text="Email Subject:"
        android:textColor="#0F9D58" />
  
    <TextView
        android:id="@+id/textView3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/editText3"
        android:layout_alignBottom="@+id/editText3"
        android:text="Email Body:"
        android:textColor="#0F9D58" />
  
    <!-- Button to send email -->
    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText3"
        android:layout_alignLeft="@+id/editText3"
        android:layout_marginLeft="76dp"
        android:layout_marginTop="20dp"
        android:text="Send email!!" />
</RelativeLayout>

Step 3: Working with the MainActivity File

Go to the MainActivity File and refer to the following code. Below is the code for the MainActivity File. Comments are added inside the code to understand the code in more detail.

In MainActivity Intent object is created and its action is defined to ACTION_SEND to send an email, with Intent three extra fields are also added using the putExtra function. These fields are:

  • Email of receiver
  • Subject of email
  • Body of email

setOnClickListener is attached to a button with the intent object in it to make intent with action as ACTION_SEND to send email and intent type as shown in code.

Here is the complete code to send email through intent from the android application:

Java




import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import androidx.appcompat.app.AppCompatActivity;
  
public class MainActivity extends AppCompatActivity {
  
    // define objects for edit text and button
    Button button;
    EditText sendto, subject, body;
  
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
  
        // Getting instance of edittext and button
        sendto = findViewById(R.id.editText1);
        subject = findViewById(R.id.editText2);
        body = findViewById(R.id.editText3);
        button = findViewById(R.id.button);
  
        // attach setOnClickListener to button with Intent object define in it
        button.setOnClickListener(view -> {
            String emailsend = sendto.getText().toString();
            String emailsubject = subject.getText().toString();
            String emailbody = body.getText().toString();
  
            // define Intent object with action attribute as ACTION_SEND
            Intent intent = new Intent(Intent.ACTION_SEND);
  
            // add three fields to intent using putExtra function
            intent.putExtra(Intent.EXTRA_EMAIL, new String[]{emailsend});
            intent.putExtra(Intent.EXTRA_SUBJECT, emailsubject);
            intent.putExtra(Intent.EXTRA_TEXT, emailbody);
  
            // set type of intent
            intent.setType("message/rfc822");
  
            // startActivity with intent with chooser as Email client using createChooser function
            startActivity(Intent.createChooser(intent, "Choose an Email client :"));
        });
    }
}

Kotlin




import android.content.Intent
import android.os.Bundle
import android.widget.Button
import android.widget.EditText
import androidx.appcompat.app.AppCompatActivity
  
class MainActivity : AppCompatActivity() {
  
    // define objects for edit text and button
    private lateinit var button: Button
    private lateinit var sendto: EditText
    private lateinit var subject: EditText
    private lateinit var body: EditText
  
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
  
        // Getting instance of edittext and button
        sendto = findViewById(R.id.editText1)
        subject = findViewById(R.id.editText2)
        body = findViewById(R.id.editText3)
        button = findViewById(R.id.button)
  
        // attach setOnClickListener to button with Intent object define in it
        button.setOnClickListener {
            val emailsend = sendto.getText().toString()
            val emailsubject = subject.getText().toString()
            val emailbody = body.getText().toString()
  
            // define Intent object with action attribute as ACTION_SEND
            val intent = Intent(Intent.ACTION_SEND)
  
            // add three fields to intent using putExtra function
            intent.putExtra(Intent.EXTRA_EMAIL, arrayOf(emailsend))
            intent.putExtra(Intent.EXTRA_SUBJECT, emailsubject)
            intent.putExtra(Intent.EXTRA_TEXT, emailbody)
  
            // set type of intent
            intent.type = "message/rfc822"
  
            // startActivity with intent with chooser as Email client using createChooser function
            startActivity(Intent.createChooser(intent, "Choose an Email client :"))
        }
    }
}

Output:

Send an Email from an Android Application
