Android Knife Steel Chart Mobile 3.99.2

As the title suggests, this is a mobile version of the Interactive Knife Steel chart, for the Android OS based smartphones. Detailed information on its use is in the application help file. Given the size constraints of the small device, the layout is different compared to the table layout based user interface in the online chart. Functionality mainly is the same, but there still are differences. Mobile chart is functional without active internet connection. Links to web pages from the steel notes will not work without connection to the internet, however steel compositions, name references, notes and internal links go other alloys are available offline. Usually, the application database is a snapshot of the online database close to the release date. However, starting with version 2.0 the updates for the steel data can be downloaded from the central database automaticaly, keeping your phone database always up to date.

Application requires Anrdoid OS 1.6 and API level 4.

  • Database updates - The app can connect to the online version of the Knife Steel Chart and download fixes and updates since last checkup. Reminders can be set up daily, weekly, montly or disabled.
  • Steel browser view automatically shows/hides toolbar to call comparison graph or clear selection as the user selects/deselects alloys, no longer need to click menu button to choose graph or clear selection operations.
  • Filter dialog has a few improvements too: Disabled autosuggest for text fields, considering very specific search terms, it wasn't working. For all text fields, clicking Enter button on the soft keyboard has the same effect as slicking Search button in the same dialog, i.e. executes search operation using selected filters. For all text fields, * wildcard is automatically appended at the end of the text, since typing that on the phone is more cumbersome.
  • Steel detail view reference alloy names are now navigation links, you cna click them and navigate to the alloy data.
  • Graph view - Touching bar group for any element displays popup with exact composition values as before, but now with color coding and alloy name as well.
  • Error reporting - If a critical error happens during installation or database updates, the app will catch it (hopefully all of them) and prompt you to send the error to developer, that'd be me. Besides crashes, there is a chance that I will make a mistake when updating main database, so during an update you may get an error about orphan compositions, or things like that. If you encounter one before me, please send the error report, just once though.
  • Version 1.0 - 10/06/2010: Initial version.
