Changelog (Android version)

1.12 (2017-06-12)

• If there is no explicit font-color-per-current-category set and default font color has low contrast (low visibility) in the current background color, font color is automatically set to black or white, depending on which has greater contrast.
• Fixed typos in new Settings.
• Fixed some problems with screen orientation change.

1.11 (2017-06-10)

• Implementation of colors-per-category (background and fonts). Child-categories (subcategories) inherit colors from parents. The colors can be changed by long-click on "Reviews" or pressing "Input", then long-click on a category, then picking "Change colors" from menu "Edit".
• Possibility to set default background color and default font color in Settings.
• Explicit use of Holo Theme (may fix visual inconsistencies on some devices).

1.10 (2017-05-26)

• New look.
• Grade-buttons are colored and scaled to the height of screen.
• Added support for both Samsung's MultiWindow mode and official MultiWindow in Android 7.0.
• New keyboard shortcuts in Reviews mode: alt+q, alt+a: open question and answer image in fullscreen; ctrl+q: moves item to queue; ctrl+alt+z: cancel last grade.
• Many small changes, fixes and improvements.

1.9 (2017-04-02)

• Added menu button on screen (as some recent Android-based devices, esp. from Samsung, doesn't display menu button on navigation bar).
• "Force" button is hidden if there are scheduled reviews for today.
• More keyboard shortcuts: "Del" key (and Ctrl+D) allows to delete element, Ctrl+E toggles edit-mode.
• Answer image preloading in background to speed-up revealing answers with image.
• Bugfix: changes in edited items found through Find facility could have been not saved.
• User's font preferences are also used in Find facility.
• Added support for adding https images in Input mode.

1.8 (2017-03-31)

• Fixed problems introduced in 1.7: when item is in edit-mode, pressing backspace would mix things up.

1.7 (2017-03-28)

• Fixed possible crashes on Android 7.1 when selecting a different directory for database or for a backup-destination.
• "Backspace" on a keyboard is a shortcut to "Hint".
• "Space" on a keyboard is a shortcut to "Ok" (revealing answer).
• Pressing "f" on main FullRecall screen is a shortcut to "Find" feature.

1.6 (2017-03-17)

• Minimum Android version supported is 2.3 (previous versions worked on Android 2.2).
• Added support for more SD-card paths (although by default, on most non-rooted devices, FullRecall doesn't have write permissions to external SD card).
• Clicked images are opened scaled-up to fit window.
• If there is roaming in effect, FullRecall still uses Internet.
• Grade-buttons are enabled with some delay to prevent accidental pressing them just after pressing "Ok".
• Bugfix related to network-sync of multimedia files (the files could have be downloaded needlessly).
• Bugfix: changes made during editing item after finding it could have been discarded.
• Some small bugfixes; including a possible fix for a rare situation, that I was unable to reproduce, that could have resulted in wiping out learning database; making regular backups is still recommended.

1.5 (2015-10-03)

• Fixed possible crashes on some recent Android versions; crashes were possible if spellchecker was turned on in Android's options.
• Revamped code dectecting SD cards, to list external SD card.

1.4 (2015-09-03)

• Added support for downloading images from secure-http (https).
• Less CPU usage (i.e. longer battery life).

1.3 (2013-07-06)

• Added support for external storage on other paths than /sdcard/ and other improvements in dialog that allows to select another directory for database: if destination dir is empty, dialog proposes to move or copy current database there; in this way it's now possible to move database from main memory to SD card.
• Minimum height of every grade button in large-display mode is now 80dp to fix situation when a large question image would make grade buttons small.

1.2 (2013-02-23)

• Bugfix: custom fonts in version 1.1 weren't available.

1.1 (2013-02-22)

• there is a dialog, during network operations, that informs about the network operation taking place
• "network sync on exit" takes place in background service (until it finishes) even after FullRecall window is gone, so FullRecall can exit faster.
