Currently, I have two apps in the Android Market: Smartlock and Bluetooth Volume. Each has a free and paid version. They have been downloaded over 50,000 times and have an average rating of 4 out of 5 stars. The app I submitted to the Android Developer Challenge 2 was rated in the top 25 percent of all submissions (the highest non-winning ranking that Google disclosed).
I have been programming with Android since the day the first beta SDK was released.
