Android : List Of Droids MIME Types?

I can't seem to find out how a MIME type is found. For instance, say I want my application to bring up Contacts. Where can I find the MIME type for that task? I currently have the following:

Intent intent = new Intent(); intent.setAction(Intent.ACTION_GET_CONTENT); intent.setType("*/*");

Intent newIntent = Intent.createChooser(intent, null); startActivityForResult( newIntent , SHOW_VERIFY_ACTIVITY );

And the wildcards work. But I would like to be more explicit. Like the following:

intent.setType("vnd.android.cursor.item/contacts");

...but is not valid.
