Acron RPN announces v3.0 BETA

[vanLudwig]

UI layouts can be authored in XML, saved with the .acronrpn file extension, and loaded exactly like a saved stack .acronrpn file. Only the paid version of Acron RPN can change layouts. Here’s some useful downloads to get started:

• Creating Layouts Reference Documentation
• Extremely primitive layout based on the Casio SL-240LB. This is a good place to start if you want to write a layout from scratch, especially if you are trying to mimic a physical calculator.
• Stock layout provided with Acron RPN. This is a good place to start if you want to make changes to the default layout.
  

A few things to remember:

• Regardless of what your layout looks like, Acron RPN is always an entry-style RPN calculator with an unlimited stack. Layouts give you a lot of flexibility on how the app looks, but minimal flexibility in how it acts.
• If there is a bug in your layout, Acron RPN will give an error message that should be sufficient to locate the problem. It will continue to use the previous layout until a new layout is successfully installed. Once a new layout is successfully installed, you will be forced to restart the app.
• Layouts can be loaded from the stack -> open button, or launched directly from Google Drive, Downloads, a web browser, etc. Launching from Google Drive, etc. becomes necessary if your installed layout doesn’t expose an open button.
• If something goes wrong, you can always get back to the stock layout by using “Clear Data” from Settings -> Apps -> Acron RPN Calculator -> Storage.
