Just completed my first project with Android Platform.
I ported Moblica‘s Snaptu application from J2ME to Android. The guys at Moblica did a great job keeping the interface as open as possible, thus the port to Android was not that difficult. Most of the challenge was to adapt the code to Android Model of activities and API.
The Android application is still in alpha, thus only selected users get to test it, but expect it in the Android Market soon.
In the meantime make sure you check out Snapu , these guys are good (and happen to be my friends).
