Android Developer Challenge 2 which was open for public review, is now closed, and the top winners will be announced this coming Monday, November 30.
During public judging or review, Android users can download the ADC2 app from Android Market and install it on their mobile devices.

When the ADC2 app is opened, it will manage the download of applications for review. Reviewers are not required to submit review upon a specific timeframe.
Applications are reviewed by rating their concept of use, effective use of the Android platform, polish and appeal and also its indispensability.
When a review of an app has been submitted, the ADC2 app will proceed to download the next app for review and the cycle continues.
There are many apps which are productivity tools but one that has always been my favourite is Grooveshark for Android.

Grooveshark is a music and radio player, which allows you to search for music and play it (playlist enabled), or play songs randomly (radio). The music or songs are high in quality and the streaming does not seem to lag at all. Just so you know, Grooveshark streams online for free too.
I did not manage to review all of the apps, but I’m sure the top winners effort are well worth it.
Prizes will be distributed as follows; all prizes are in USD:

Google has just announced that the submission site for Android Developer Challenge 2 has been open.
I wouldn’t need to go into details, as if you are ready for your Android application submission, you should be checking out the ADC submission site thoroughly and I wish you the best!
The important thing to remember is that your submission must be entered by 11:59:59pm Pacific Time in the United States on August 31, 2009. If you’re not sure about the exact time, check out the Pacific Time.

This is one of the nicest contest for Android users or fans.
The best Android contest so far is undeniably the Google Android Developer Challenge, but numerous Android related contests have been mushrooming.
Vodafone has another Android contest which runs from 9th August 2009 til 30 September 2009 and the best of it is, you do not need to develop the application yourself. (OK, so this might not sound so good for die-hard Android developers).
All you need to do to join is make sure you are above 16, resides in the United Kingdom of Great Britain and Northern Ireland.

Then, think of an Android application idea and submit it to Vodafone for a chance to win £1000 in cash, and/or a HTC Magic phone.
The grand prize winner will also have the idea developed by Vodafone and submitted to Android Market.
This, I think, is the easiest as it gets for an Android contest.
