I’ve been browsing on-line greater than 3 hours as of late, but I by no means discovered any interesting article like yours. It?s pretty price sufficient for me. In my opinion, if all website owners and bloggers made just right content as you did, the internet might be a lot more helpful than ever before.

The answer is Microsoft.

Congrats to Gil who named the correct answer and was the \"third\" to do so. Note to self... come up with more challenging questions as everyone has answered it correctly thus far!

Hi Frank,

enjoying your articles. I wouldn't call the Android Application object a "global variable" (container) though. Global / local variables are about scope and visibility whereas Application / Activities are about lifetime.

If you have an App with a couple of Activities that control interaction with an underlying data structure I do not see any reasonable argument against making the data structure part of a custom Application object. Again, I don't see an alternative and doubt that getting references to the Application object breaks with encapsulation in the way global variables do.

Frank,

This is a very nice and direct article.
Congratulations.
Please try to be as objetive as you were here on your next book.
Don't forget that the way you pass information on a site is different than the way you should present it on a book.

Well, seriously, this is the kind of attitude that paves way for iconic software’s and sometimes legendary ones. Take the case of Apple for instance, the “Would it be possible to” and “Get it done” phrases you said here can be heard there very often and that is why most of us enjoy flawless products like the iphone app design, iPod, Macs or whatever that is Apple. I totally agree with you regarding the production codes. Coming up with one may take some time and is certainly tiresome but when it is well written and maintained over time, it usually ends in top-class!
