New Feature: Book Code Downloads

Many readers have found it difficult to access the book code downloads from the official publisher site. After some discussion with our editor, we are pleased to inform you that we now have them hosted separately and available for easy, direct download. (No login should be needed and certainly no verification that you own the book. But you already bought it, right? :) )

In addition to providing a new source for downloading the files, we have also provided a single download for all of the code for each book.

The download link is convenient found right next to the Home link above, under "Book Code Downloads."

Happy Android Coding!

Reader Feedback: Trivia Quiz Server Bug

Bugs happen! 

In Hour 17 of Sam's Teach Yourself Android Application Development in 24 Hours, you learn about AsyncTasks. You use one to send a request to the server to add a friend based upon their email address. What's supposed to happen is that the server looks up the email address and if it finds a match, it adds that user to your list of friends, which is stored on the server. Then, when the Scores Screen is updated to download scores of your friends, the server will return XML containing just that. It will not return email address or anything like that -- we don't want privacy leaks.

What was happening?

Nothing!

Nothing? That's right. The server was failing to find any friends -- regardless of the email address. It was, however, returning the correct status. We just didn't bother with doing anything more with the status than printing it out to LogCat. Whoops.

Fixed

The fix was simple. The Google App Engine server has been updated to version 3 and, after some brief testing, we promoted this to the default server.

If you were having trouble with adding friends, now you know why.
