Android Developer Challenge 2 winners announced

Google have announced the winners of the second Android Developer Challenge, with the three top apps being SweetDreams, What the Doodle!? and WaveSecure.  Decided by a combination of public vote and Google's own say, the full list stretches to 200 apps and ranges from gaming through utilities to social networking apps.

SweetDreams is a power/alert management app that automatically shuts off notification sounds as well as unused wireless connectivity during the night, so that the handset's battery is extended.  What the Doodle!?, meanwhile, is a multiplayer online game similar to Pictionary, in which players must guess a phrase from a doodle drawn on an Android device.

Finally, WaveSecure offers a combination of remote security, data backup and tracking, allowing you to track your handset's location via GPS, lock or wipe it, and see online records of your data.  You can find the full list of winners here.
