Build an Android GPS Running Tracker
Experience in Google Maps is a must
1)Track Speed,Distance,Time & Calories
2)Leaderboards with Filter and Sort
3)Users unlock levels as they burn calories during life time
4)Users Win Medals based on events (1st 42Km Ran,1 night run,etc)
5)Use Activity Recognition API to get current mode of travelling(car,bicycle,Foot,etc).If the result is NOT "Foot",ignore distance travelled of the corresponding time.
