Hello,
I just got the book, and wanted to look at the code downloads. It looks like there is an error in Chapter 2 with the first exercise.

I downloaded the code for the book and did a virus scan. AVG flagged
Android_ctl
AVG detects this highly active Webthreat and its 425 known variants.

So I cannot use the code.
Any ideas? This is pretty series.

Thanks,
Sam

Yes, you can use source code - those are false positive, as AVG detects that binaries (compiled from source code) are accessing SMS and location services, so AVG assumes (without actually knowing what is purpose of these binaries) that someone wants to spy on your location and SMS.

If you are so concerned you can safely delete those DEX (compiled binaries) and when you compile android source files you will get them again. In this special case it's might be even good idea to turn off AVG for folder where you develop Android applications to prevent it's interference, although I had no problems like that so far and I developed dozen of Android apps and I have AVG as well.
