                dateAdded = audioCursor.getInt(dateAddedColumnIndex); 

                 // do action

 
            } while (audioCursor.moveToNext()); 

       }
    }

 ==========================================

After querying audio, audio columns index get from audio cursor column index.
Each audio information can get from current audio cursor by moving audio cursor index.

This example gets the audio id, path, display name, title, duration, artist, album, added date from MediaStore.
After received audio data, it can be used to load thumbnail, play audio etc.
