I could be interested at some time in the future. I'm not sure when as
I am doing a new system in Windows, for which I would like to have
initially an Android app for a particular purpose. At the moment, I am
too busy with the Windows code to have time to do much with Android.
If you don't do anything with them now, perhaps I can get in touch with
you when I am ready. I always create my components at run time, so an
installer might not be necessary anyway.
Will there be source available ? I would need that if I decided to use
