[Jourdelune]

Greetings,

I am new around the Android apps technology.

Nothing beat having my hands on actual code sources to learn.

After more research than anticipated over google, I am here to got some clue about where to find some nice open source android apps.

I am more curious about application that use google maps API and the GPS (geolocation) to start exploring if you know any.

Anyway, I am taker for any great Android Apps source code to start exploring.

So please, feel free to post your link about android app source code.
