Packt Publishing ran a contest last week to find out which mobile OS had the most love from fans. You'll never guess which won. Okay, maybe you can guess–we wouldn't be posting about it if iOS had won. Android took the win by a landslide with 87% of the vote. To celebrate, Packt is holding Android Week with 70% off on twenty great titles about Android development, not to mention giving away a free eBook every day.

The sale has switched to 70% off instead of 50% off. Yay savings!

The first free eBook in the lineup is Android Database Programming, but there's a pretty good chance most of our readers have already claimed it since it was one of the first books to be given away when Packt first started this promotion back in December. If you don't already have it, head over to Packt's free learning page to claim it before today is over. You should also bookmark that page and keep checking back every day to claim new books as they become available.

Don't forget to also check out the sale on Android development books. If you need something specific for your development work, Packt is selling 20 titles at 70% off their regular price. The sale and free eBooks (at least for Android-specific content) will last until March 28th, so keep a close eye on Packt through the rest of the week.
