Google announced details of the second Android Developer Challenge competition at its Google I/O event in San Francisco yesterday.  The new ADC will result in 30 winning applications that will get a share of US$1,975,000 in total prize money.

This time around the competition will be broken down into 10 categories, and actual users will get a chance to test and vote for the applications in both rounds of the competition.  In the end, first, second, and third place in each category will be awarded $100k, $50k, and $25k (respectively).

There will also be 3 applications awarded “overall” prizes.  First place overall will receive an additional US$150k, while second and third overall will receive $50k and $25k.  All overall awards are in addition to any category prizes that an application might have picked up.

All in all, that’s up to a quarter million dollars that one application can earn.
