Mobile software development can be a challenge, especially given the plethora of tools, technologies and requirements needed to create them. There’s a great resource available, called Don’t Panic Mobile Developer’s Guide to the Galaxy, which is very popular and is now in its 8th edition.
I am Julian Harty, and I’m one of the contributors. eBay is a sponsor of the US edition to allow distribution at various events.
