Latest code available for download.
Added features from SETTINGS menu:
Swap settings symbols for text labels that operate from long press on the keys below each lable
Swap Days function for X Squared function
Swap Banner for Edittext box. Text is assumed to be a name and is used in the voice greeting
Turn off/on voice greeting

This project started as a 4 function calculator to impress the grandchildren, since then I have used it as a test bed for any idea that came to mind. Subsequently it now has more bells and whistles than a party hire shop.
I hope that some bits of the code are of help to others starting out.

BrownPaper Calculator has been updated on Play Store and the link above to the source code has also been updated.

This new version adds a choice of languages [including Klingon] to the TALK function. These language files can be exported/edited/imported.
Another bell, another whistle.
