Well, i dev a 1.4BT android app (i can't wait anymore 1.5 realese!!! :-))) waiting to 09/15/11!!!) for my fencing club, and a want to use push notification to inform players punctually. I make some research about push in android and i understand that android use C2DM system. So i sign up here : http://code.google.com/intl/fr/android/c2dm/signup.html and after i try to understand this doc http://code.google.com/intl/fr/android/c2dm/ but it's soooooooo difficult.... i'm a novice in programmation and it's very difficult for me. So is someone succed in the implatation of C2DM in BT app? or do you use other thing to push in android? Thanks so much for your help

I really like Urban Airship for push notifications. I haven't tried integrating with Droid yet, but have several iphone apps working with UA. Here's the link to check them out: http://urbanairship.com/products/push-notifications/
