For example, there txt, doc, there are other formats can correspond to a corresponding text format, then we can put them into a normalized return this MIME type:.. Vnd.android.cursor.item / vnd.example. text
You can then use this to open the way to make the corresponding action (action can open any text file)

The type depends in part on whether or not the content:
URI submitted to getType () limits the request to a specific record.
There's one form of the MIME type for a single record and another for multiple records.
Use the Uri methods to help determine what is being requested. (Official website doc)

ContentProvider with getType (Uri uri) uri represents the data returned MIME type, if the data may contain many records, MIME type string vnd.android.cursor.dir / begin with, if the data contains only one data to vnd. android.cursor.item / beginning.
