I released my first Kawa Android app to the Play Store:
https://play.google.com/store/apps/details?id=net.quantiana.pluvia
It is a near-real-time NEXRAD weather radar data viewer.
For raw numerical performance, I wrote the radar data pre-processors
using the Android NDK in C.
All the JVM code is in Kawa Scheme. It contains 0 lines of Java code.
The networking, jsoup XML parsing, OpenGL rendering, touch callbacks,
sensor callbacks, forecasting and 2D and 3D compositing were all
written in Kawa Scheme using live programming over a telnet REPL.
I posted the majority of the code here:
github.com/rafleon/KawaDroid
It is notable that Kawa Scheme has sufficient stability and
performance to do real-time 3D data visualization on Android.
Cool! I downloaded it, but today is not a good day for testing.
But more rain is expected soon ...
Perhaps you might consider writing an article about your experience,
for some website you're familiar with?
