Messaging Activity pops up along with mail application in Android
<p>I wrote an email application in Android , that uses <code>Action_SEND</code> intent. When I <code>call startActivity(i);</code> where i is intent, along with email Application , messaging application is also popping up. But when I wrote an application for email why should messaging application also should pop up.
can I be explained clearly regarding this concept.</p>

<pre><code>Intent sendIntent = new Intent(Intent.ACTION_SEND);
String[] mailto = recipients;
sendIntent.putExtra(Intent.EXTRA_EMAIL, mailto);
String[] mailCc = recipientsToBeCopied;
sendIntent.putExtra(Intent.EXTRA_CC, mailCc);
String[] mailBcc = recipientsToBeBlindCopied;
sendIntent.putExtra(Intent.EXTRA_BCC, mailBcc);
String subject = strSubject;
sendIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
String body = strBody;
sendIntent.putExtra(Intent.EXTRA_TEXT, body);
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, "send mail.."));
</code></pre>

<p>Can any one tell me reason for using <code>createChooser</code> of intent and also reason for this application popping up messaging activity. </p>
