OK  so bad news for me - no support of external SD cards (yes  I keep my DB on external SD  my key on """"""""""""""""internal"""""""""""""""" SD). Didn't triggered permission request. Well  thankfully I could use Android Picker to select the file through some of the file managers I use. Stock Lollipop. BTW  Look&feel needs some significant changes -it's no Gingerbread era anymore  and displays happen to be larger than 320x240  3"""""""""""""""" beauties. Uninstalled.""
