title: Multiple android.intent.action.MAIN in manifest xml file
body: <p>I am new to Android development I seen lots of tutorial where they have only <code>android.intent.action.MAIN</code> which is basically a start activity of the application. </p>
  
  <p>But, in the android app demos, I have seen multiple <code>android.intent.action.MAIN</code> statements in <em>mainfest.xml</em>.  Can anyone explain why the <code>mainfest.xml</code> has multiple <code>android.intent.action.MAIN</code> statements?</p>
  
  <p>And, in which scenarios we are supposed to have multiple <code>MAIN</code>s in manifest.xml?</p>
