With Android being listed as the best-selling smartphone platform worldwide, it comes as no surprise that developers are flocking to its Android Market, which already has around 320,000 apps available as of September 2011 (374,303 as of Feb 5, 2012). A full 74 percent of those are free apps and while giving apps away doesn’t net a developer money off the bat, it’s still by far the best way for an app to become popular and gain traction in any app marketplace.
