title: Android CONTENT TYPE - Is vnd.android.cursor.dir some standard constant defined by android?
body: <p>I have very basic understanding problem of Content types.</p>
  
  <p>I went through lot of examples and text explaining the above term, but still have some basic understanding problem. Can some clarify me please.</p>
  
  <p>In the android notepad example, and many others, it is mentioned vnd.android.cursor.dir/ resolves to a list of items in a directory and vnd.android.cursor.item/ refers to specific item in a directory.</p>
  
  <p>Is this vnd.android.cursor.dir some standard constant defined by android. Where did this come from?, or can i change it like</p>
  
  <p>vn.com.android.myexample.dir/
  
  <p>How is this even resolved and what is its purpose, why not use the full CONTENT_URI?</p>
  
  <p>Sorry, i'm totally lost, and don't understand this.</p>
