In Android, you can use Intent.ACTION_SEND to call an existing email client to send an Email.

See following code snippets :

	Intent email = new Intent(Intent.ACTION_SEND);
	email.putExtra(Intent.EXTRA_EMAIL, new String[]{"youremail@yahoo.com"});		  
	email.putExtra(Intent.EXTRA_SUBJECT, "subject");
	email.putExtra(Intent.EXTRA_TEXT, "message");
	email.setType("message/rfc822");
	startActivity(Intent.createChooser(email, "Choose an Email client :"));

P.S This project is developed in Eclipse 3.7, and tested with Samsung Galaxy S2 (Android 2.3.3).

Run & test on real device only.
If you run this on emulator, you will hit error message : “No application can perform this action“. This code only work on real device.

        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Send" />

</LinearLayout>

2. Activity

Full activity class to send an Email. Read the onClick() method, it should be self-explanatory.

package com.mkyong.android;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class SendEmailActivity extends Activity {

	Button buttonSend;
	EditText textTo;
	EditText textSubject;
	EditText textMessage;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		buttonSend = (Button) findViewById(R.id.buttonSend);
		textTo = (EditText) findViewById(R.id.editTextTo);
		textSubject = (EditText) findViewById(R.id.editTextSubject);
		textMessage = (EditText) findViewById(R.id.editTextMessage);

		buttonSend.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {

			  String to = textTo.getText().toString();
			  String subject = textSubject.getText().toString();
			  String message = textMessage.getText().toString();

			  Intent email = new Intent(Intent.ACTION_SEND);
			  email.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});
			  //email.putExtra(Intent.EXTRA_CC, new String[]{ to});
			  //email.putExtra(Intent.EXTRA_BCC, new String[]{to});
			  email.putExtra(Intent.EXTRA_SUBJECT, subject);
			  email.putExtra(Intent.EXTRA_TEXT, message);

			  //need this to prompts email client only
			  email.setType("message/rfc822");

			  startActivity(Intent.createChooser(email, "Choose an Email client :"));

			}
		});
	}
