  • I created DONATION app, from now on u can donate via PayPal or newly directly via Market – "buy" DONATION app
  • I created new sister application to MKCommander (MKC) called MKCommander HD (MKC HD). What's difference? Mostly in memory limits!
    • both app's share almost same code 99%
    • original MKCommader can run on any Android 2.1+,  so also on  phone/tables with Honeycomb and  ICS
    • new MKCommander HD can run ONLY on Android 3.0 and higher,
    • if u have eg. phone with ICS, u can choose between MKC and MKC HD; if u have phone with Gingerbread only MKC is possible
    • Why I created this new app?  My HTC Sensation upgraded to ICS 4.0.3 and I wanted to get maximum of ICS – see limits:
      • orig. MKC can use up to 16/24/32/48MB of RAM (depeds on Android version and device), most of time it's enough, but if u try to create tbumbsnails in dir with 1000+ pictures u can ran out of mem, also if u want to try to open big/huge jpeg (9000×8000 pixels, 10MB size), such jpeg must be resampled to lower resolutions +-3000×3000, eg. Map of Tyria)
      • MKC HD can use up to 128MB of RAM (on rooted phones even more), so opening huge jpeg (eg. Map of Tyria) in full resolution is no problemo.
  • directory bar
    • free space is now shown (usefull for rooted phones)
    • on click and on long click actions can be assigned
  • TextViewer:
    • added Search functionality, added switch for read-only <-> read-write (edit functionality)
    • u can create new text file
    • NOTE: TextViewer is not intended to open large binary data, u can ran out of memory in such case
  • Settings:
    • u can choose if u wanna keep horiz. toolbar in fullscreen mode
    • u can choose text color of toolbar buttons
    • u can choose text color and background color of selected objects (this colors are also used for top+bottom statusbar)
    • new assignable functions for V+H toolbars
  • in MkDir dialog, u can choose if u wanna create empty Folder or file
  • fixed bug:
    • on ICS in Settings,
    • in Properties – after 'file find' file's true location was not correctly displayed
    • after leaving directory, directory was not highlighted
  • new permisions:
    • WRITE_MEDIA_STORAGE – seems like tablets with Honeycomb that have internal+external memory(=sd card) need this permission for read+write access to both memory
    •  MOUNT/UNMOUNT – needed for un/mounting filesystems on rooted phones

0.8.23   (29.3.2012)

0.8.22   (13.3.2012)

  • Storage Analysis(SA) enhanced – graphs added (bright color shows ratio file size / sdcard size, dark color shows ratio file size / current directory size), u can hide graphs by clicking on "Exit SA" on the top

  • Properties dialog heavily recoded
  • Thumbnails are now cached, so when visiting picture folders repeatedly thumbnails are shown much faster(up to 10x) for larger images (only images >100kB are cached)
    NOTE: if u wanna recreate thumbnails in current folder: long tap on any object in folder->Other->Recreate thumbs for this folder
