How to send email from your application

SDK Version:

Today we'll create an easy email sender application.
First of all we need to create a layout to set the address, the subject and email body box.

<?xml version="1.0" encoding="utf-8"?><LinearLayout android:id="@
 
+id/LinearLayout01" android:layout_width="fill_parent" 
 
android:layout_height="fill_parent" 
 
xmlns:android="http://schemas.android.com/apk/res/android" 
 
android:orientation="vertical"><LinearLayout android:id="@+id/LinearLayout02"; 
 
android:layout_width="wrap_content" android:layout_height="wrap_content" 
 
android:orientation="horizontal"><EditText android:layout_width="wrap_content" 
 
android:layout_height="wrap_content" android:width="170dip" android:id="@
 
+id/emailaddress"></EditText><TextView android:layout_width="wrap_content" 
 
android:layout_height="wrap_content" android:id="@+id/emailaddress" 
 
android:text="Email address"></TextView>
</LinearLayout>
 
<LinearLayout android:id="@+id/LinearLayout03"; 
 
android:layout_width="wrap_content" android:layout_height="wrap_content" 
 
android:orientation="horizontal"><EditText android:layout_width="wrap_content" 
 
android:layout_height="wrap_content" android:width="170dip" android:id="@
 
+id/emailsubject"></EditText><TextView android:layout_width="wrap_content" 
 
android:layout_height="wrap_content" android:id="@+id/emailsubject" 
 
android:text="Subject"></TextView>
</LinearLayout>
<EditText android:layout_width="wrap_content" 
 
android:layout_height="wrap_content" android:lines="5" android:width="300dip" 
 
android:id="@+id/emailtext"></EditText>
<Button android:layout_width="wrap_content" android:layout_height="wrap_content" 
 
android:id="@+id/emailsendbutton&quot; android:text="Send!" 
 
android:width="150dip"></Button>
</LinearLayout>

Ugly, but works...
Next we create a new class, called ....uhhhm...Email, then modify like this:

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 Email extends Activity {
        Button send;
        EditText address, subject, emailtext;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.email);
        send=(Button) findViewById(R.id.emailsendbutton);
        address=(EditText) findViewById(R.id.emailaddress);
        subject=(EditText) findViewById(R.id.emailsubject);
        emailtext=(EditText) findViewById(R.id.emailtext);
        
        send.setOnClickListener(new OnClickListener() {
                        
                        @Override
                        public void onClick(View v) {
                                // TODO Auto-generated method stub
                                  
                                      final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
                                
                                      emailIntent.setType("plain/text");
                                 
                                      emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{ address.getText().toString()});
                                
                                      emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject.getText());
                                
                                      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailtext.getText());
                        
                                    Email.this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
 
                        }
                });
    }
}

It will use the button's onclicklistener method to send the email. It does not work on emulator, but works on real devices.
