title: Sending Email in Android using JavaMail API without using the default/built-in app
body: <p>I am trying to create a mail sending application in Android. </p>
  
  <p>If I use: </p>
  
  <pre><code>Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
  </code></pre>
  
  <p>This will launch the built-in Android application; I'm trying to send the mail on button click directly <strong>without</strong> using this application.</p>
