Announcing LambdaMC: a demo Haskell Android app to calculate option prices by Monte Carlo simulation built with the ghc-android tool. Based on the example app at https://github.com/neurocyte/android-haskell-activity Functionality is limited, but it may be a useful reference for anybody developing a Haskell Android app: - Android Pause / Resume functionality. - Screen Rotation support. - Background worker thread updates the UI when the calculation is complete. - Interaction between various Android UI elements and Haskell code.
