The number of Android applications increased in 2009 from an issue of dozens to an issue of 20,000. Could we see apps skyrocket again in 2010? According to Flurry, the Android Market app total could reach as high 150,000 a year from now.

Flurry, which tracks app analytics and monetization opportunities, estimates that Android will have between 100,000 and 150,000 apps by the end of 2010. Flurry doesn’t list any reason or explanation to support this estimate, but Flurry CEO Simon Khalaf told Businessweek, “A lot of developers have come onto the Android platform because of efforts by Verizon Wireless, Motorola Inc. and Google to promote the system.”

The thought of 100,000 seems a bit ambitious. The iPhone reached that number very quickly but that support came because of popularity and a financially rewarding app store. Will Android be able to replicate that in a year and get closer to iPhone’s massive app offerings? (Note: Flurry estimates that iTunes will double its app offerings and bulk up to at least 300,000 by then).

So, Android fans: crazy or cool? Do you think Android can have that many apps in the market next year? I’d love to revisit this during Christmas 2010 to consider the accuracy of Flurry’s projections.
