That's not much of a problem since my system is setup to develop for Windows as well as Java and Android. I'm still interested, regardless. You'd be surprised how much of Android isn't written in Java. Kernels aren't written in Java and from sources I've seen, Recoveries aren't written in Java either.
I'm trying to venture away from programming for Windows and into programming for Android devices. I'm most comfortable with C as that's the language I have the most experience in. I can program in Java/Android, just not too much experience. Since I learn best by trial and error and by reading source code, I thought this would be a good place to start since it involves both languages.
