如何从ContentResolver查询中获取跟踪Uri？

Question

i am traversing in the phone's memory with the following code.

ContentResolver contentResolver = getContentResolver();
    String[] columns = {
            MediaColumns._ID,
            MediaColumns.TITLE,
        AudioColumns.DURATION,

    };
    final String where = MediaStore.Audio.Media.IS_MUSIC + "=1";

    Cursor cursor = contentResolver.query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,columns, where, null, null);

    while(cursor.moveToNext()) {
        String urp = cursor.getString(cursor.getColumnIndex(MediaColumns._ID));
        String title = cursor.getString(cursor.getColumnIndex(MediaColumns.TITLE));
        Long duration = cursor.getLong(cursor.getColumnIndex(AudioColumns.DURATION));
    }

so now my question is, how to get the uri of the cursor items traveresed, like for first while run i have stored id,title,duration etc metadata and i would also like to store that tracks URI, also i would like to convert that URI from content// scheme to file scheme.

Any help will be greatful thankyou
