How to send email from your application

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.

1. <?xml version="1.0" encoding="utf-8"?><LinearLayout android:id="@
2.  
3. +id/LinearLayout01" android:layout_width="fill_parent"
4.  
5. android:layout_height="fill_parent"
6.  
7. xmlns:android="http://schemas.android.com/apk/res/android"
8.  
9. android:orientation="vertical"><LinearLayout android:id="@+id/LinearLayout02";
10.  
11. android:layout_width="wrap_content" android:layout_height="wrap_content"
12.  
13. android:orientation="horizontal"><EditText android:layout_width="wrap_content"
14.  
15. android:layout_height="wrap_content" android:width="170dip" android:id="@
16.  
17. +id/emailaddress"></EditText><TextView android:layout_width="wrap_content"
18.  
19. android:layout_height="wrap_content" android:id="@+id/emailaddress"
20.  
21. android:text="Email address"></TextView>
22. </LinearLayout>
23.  
24.  
25. <LinearLayout android:id="@+id/LinearLayout03";
26.  
27. android:layout_width="wrap_content" android:layout_height="wrap_content"
28.  
29. android:orientation="horizontal"><EditText android:layout_width="wrap_content"
30.  
31. android:layout_height="wrap_content" android:width="170dip" android:id="@
32.  
33. +id/emailsubject"></EditText><TextView android:layout_width="wrap_content"
34.  
35. android:layout_height="wrap_content" android:id="@+id/emailsubject"
36.  
37. android:text="Subject"></TextView>
38. </LinearLayout>
39. <EditText android:layout_width="wrap_content"
40.  
41. android:layout_height="wrap_content" android:lines="5" android:width="300dip"
42.  
43. android:id="@+id/emailtext"></EditText>
44. <Button android:layout_width="wrap_content" android:layout_height="wrap_content"
45.  
46. android:id="@+id/emailsendbutton&quot; android:text="Send!"
47.  
48. android:width="150dip"></Button>
49. </LinearLayout>

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

1. import android.app.Activity;
2. import android.content.Intent;
3. import android.os.Bundle;
4. import android.view.View;
5. import android.view.View.OnClickListener;
6. import android.widget.Button;
7. import android.widget.EditText;
8.  
9. public class Email extends Activity {
10.         Button send;
11.         EditText address, subject, emailtext;
12.     @Override
13.     public void onCreate(Bundle savedInstanceState) {
14.         super.onCreate(savedInstanceState);
15.         setContentView(R.layout.email);
16.         send=(Button) findViewById(R.id.emailsendbutton);
17.         address=(EditText) findViewById(R.id.emailaddress);
18.         subject=(EditText) findViewById(R.id.emailsubject);
19.         emailtext=(EditText) findViewById(R.id.emailtext);
20.        
21.         send.setOnClickListener(new OnClickListener() {
22.                        
23.                         @Override
24.                         public void onClick(View v) {
25.                                 // TODO Auto-generated method stub
26.                                  
27.                                       final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
28.                                
29.                                       emailIntent.setType("plain/text");
30.                                  
31.                                       emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{ address.getText().toString()});
32.                                
33.                                       emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject.getText());
34.                                
35.                                       emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailtext.getText());
36.                        
37.                                     Email.this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
38.  
39.                         }
40.                 });
41.     }
42. }

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