Android q (zhihu#665)
Browse files Browse the repository at this point in the history 
* Support Android Q.

1) "COUNT(*) AS " + COLUMN_COUNT is not working in Android Q anymore (Not sure why)
2) There are no official document specific how GROUP BY should work in CursorLoader. The unofficial workaround seem no longer work in Android Q - https://stackoverflow.com/a/33367564/72437

Due to the above 2 limitations, we need to perform manual calculation on "count per directory".

* Eliminate deprecated MediaStore.MediaColumns.DATA. We replace it with self generated Uri. However, I'm not sure whether there might be conversion failed (Uri.toString and Uri.parse) in certain edge cases.
