How to Send an Email From an Android Application?
Last Updated : 30 Jan, 2025
In this article, we 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 Implicit 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:
activity_main.xml:
XML <?xml version="1.0" encoding="utf-8"?> <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" android:background="@color/white" tools:context=".MainActivity"> <EditText android:id="@+id/editText1" android:layout_width="200dp" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentEnd="true" android:layout_marginTop="100dp" android:layout_marginEnd="22dp" /> <EditText android:id="@+id/editText2" android:layout_width="200dp" android:layout_height="wrap_content" android:layout_below="@+id/editText1" android:layout_alignStart="@+id/editText1" android:layout_marginTop="20dp" /> <EditText android:id="@+id/editText3" android:layout_width="200dp" android:layout_height="wrap_content" android:layout_below="@+id/editText2" android:layout_alignStart="@+id/editText2" android:layout_marginTop="30dp" /> <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="16dp" android:textSize="18sp" android:textStyle="bold" android:layout_alignBaseline="@+id/editText1" android:layout_alignBottom="@+id/editText1" android:layout_alignParentStart="true" android:text="Send To:" android:textColor="@color/green" /> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="16dp" android:textSize="18sp" android:textStyle="bold" android:layout_alignBaseline="@+id/editText2" android:layout_alignBottom="@+id/editText2" android:layout_alignParentStart="true" android:text="Email Subject:" android:textColor="@color/green" /> <TextView android:id="@+id/textView3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="16dp" android:textSize="18sp" android:textStyle="bold" android:layout_alignBaseline="@+id/editText3" android:layout_alignBottom="@+id/editText3" android:text="Email Body:" android:textColor="@color/green" /> <Button android:id="@+id/button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/editText3" android:layout_centerHorizontal="true" android:textSize="24sp" android:layout_marginTop="20dp" android:backgroundTint="@color/green" 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 package org.geeksforgeeks.demo; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import androidx.appcompat.app.AppCompatActivity; public class MainActivity extends AppCompatActivity { // Declare EditText and Button objects private Button button; private EditText sendTo; private EditText subject; private EditText body; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Initialize EditText and Button sendTo = findViewById(R.id.editText1); subject = findViewById(R.id.editText2); body = findViewById(R.id.editText3); button = findViewById(R.id.button); // Set OnClickListener for the button button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { 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 email details using putExtra intent.putExtra(Intent.EXTRA_EMAIL, new String[]{emailSend}); intent.putExtra(Intent.EXTRA_SUBJECT, emailSubject); intent.putExtra(Intent.EXTRA_TEXT, emailBody); // Set the type of intent intent.setType("message/rfc822"); // Start the activity with a chooser for email clients startActivity(Intent.createChooser(intent, "Choose an Email client :")); } }); } } package org.geeksforgeeks.demo 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.text.toString() val emailSubject = subject.text.toString() val emailBody = body.text.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:
