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 :"));             }         });     } }
