The Android Developer Challenge is a two-part contest whose goal is to encourage developers to build apps for the new Google mobile platform, code-named “Android.” In this first round, dubbed “Challenge I,” submissions were accepted up until April 14th. Yesterday, the top 50 entries were announced. Each of these application authors received $25,000 to fund further development of their app.

Read Write Web has a good post outlining some of the standouts, while the Android Developer Blog has the full list.
