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"

"utf-8"
?>
<!--Relative Layout-->

<!--Edit text for email id-->

android:layout_alignParentRight

</
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 :"
));
}
});
}
}
