How to send an Email from your Android App?

In this article, you will make a basic android application which 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,
subject of 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 user and button to send that email.

Step 1. activity_main.xml
activity_main.xml contains a Relative Layout which contains three Edit texts for receiver mail id, other 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 version="1.0" encoding="utf-8"?> 
  
<!--Relative Layout-->
<RelativeLayout
    xmlns:androclass="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_alignParentRight="true"  
        android:layout_alignParentTop="true"  
        android:layout_marginRight="22dp"  
        android:layout_marginTop="18dp"  
      />   
  
    <!--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_marginTop="30dp"  
        android:layout_below="@+id/editText2"  
        android:layout_alignLeft="@+id/editText2"    
      />   
  
    <!--text Views for label-->
    <TextView  
        android:id="@+id/textView1" 
        android:textColor="#0F9D58"
        android:text="Send To:" 
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignBaseline="@+id/editText1"  
        android:layout_alignBottom="@+id/editText1"  
        android:layout_alignParentLeft="true"  
        />   
  
    <TextView  
        android:id="@+id/textView2" 
        android:textColor="#0F9D58"
        android:text="Email Subject:" 
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignBaseline="@+id/editText2"  
        android:layout_alignBottom="@+id/editText2"  
        android:layout_alignParentLeft="true"  
        />   
  
    <TextView  
        android:id="@+id/textView3"  
        android:textColor="#0F9D58"
        android:text="Email Body:"
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignBaseline="@+id/editText3"  
        android:layout_alignBottom="@+id/editText3"   
        />   
  
    <!--Button to send email-->
    <Button  
        android:id="@+id/button"  
        android:text="Send email!!"
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignLeft="@+id/editText3"  
        android:layout_below="@+id/editText3"  
        android:layout_marginLeft="76dp"  
        android:layout_marginTop="20dp"  
         />     
</RelativeLayout> 

Step 2. MainActivity.java
In Main activity Intent object is created and its action is defined to ACTION_SEND to send email, with Intent three extra fields are also added using putExtra function.These fields are:

Email of receiver
Subject of email
Body of email

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

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

MainActivity.java

package com.geeksforgeeks.phonecall; 
  
import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 
import android.content.Intent; 
import android.widget.EditText; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.net.Uri; 
import android.widget.Button; 
  
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(new OnClickListener() { 
  
            @Override
            public void onClick(View 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 fiels 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 :")); 
            } 
        }); 
    } 
}
