Android Chat Application Development
android, chat, sockets
Solution
asmack and OpenFire is the easiest way. No need to reinvent the wheel.
But if you did want to RTW, then open a socket while the app is in the foreground, and use C2DM when it's not. BTW C2DM is a PITN to work with, so consider using a service like Urban Airship.
Problem
I want to create a chat application for Android and I want to know the best way to do it. My first option is to use a socket connection between the phone and the server so the server can send any new messages to the phone. The second option is to use C2DM. A chat application like what's up how is implemented with socket or using C2DM? Is there a better way to create such an application than the above? Thank you.
