I honestly don't see how java programs running in Android are much different than java programs running in any existing phone or embedded environment. I got a lot less interested in Android when I realized it's extremely Java-focused. I don't magically get fond of things you can cram in an embedded device...

I honestly don’t see how java programs running in Android are much different than java programs running in any existing phone or embedded environment. I got a lot less interested in Android when I realized it’s extremely Java-focused.

I don’t magically get fond of things you can cram in an embedded device…

I left C and C++ for Java years ago also for my hobbyist projects. I feel that Java requires lot less energy to produce working results. With Java I found that it was easy to build on stuff other people already built. And it works in reality. Upgrading libraries and runtime environments has shown be pretty painless. Repeatedly. In this sense it looks like I've found a real value in what you dislike? My very own smarthome control system, which is some kind of distributed psedudo realtime application, also runs on java (+linux). It interfaces devices through Dallas 1-wire bus, serial port devices and soon also USB I/O devices. Pretty much metal here. But yes, okay, it's not embedded. However, Android looks pretty embedded :-) Java pays off quickly when your application logic goes complex.

I've read on your site you work a lot with embedded systems. I would have liked that too, but my career took a much "higher level" direction (Java, C++ and the like). Maybe one day I'll move to Sweden... :-) Ok, got it!

Wouldn't you feel uncomfortable sticking to your preferred environment instead of using a more appropriate one for your targets just because the latter is too "simple" or not enough "on the metal" for you?

But sure, I don't write "complex business logic" software either.

'Course a Ducati is fast and compact, but a Volvo is comfortable and offers room for bags and family. The focus must be on the target. It is stupid to develop in C a clustered platform with complex business logic, which uses several enterprise resources and must be world-wide accessible in the most disparate ways. Likewise, it makes no sense to develop a project like Rockbox using Java. Personally, I find programming assembler on m68k fascinating. Yet, the elegance and readability of a well-conceived Java program is unique. Ciao Luca PS On the C++ book from Stroustrup there's a clear and compact presentation of programming paradigms (chapter 2, can be read for free at http://www.informit.com/articles/article.aspx?p=25003). It's a very interesting read!

PS
On the C++ book from Stroustrup there’s a clear and compact presentation of programming paradigms (chapter 2, can be read for free at http://www.informit.com/articles/article.aspx?p=25003). It’s a very interesting read!
