Our products still target OS 1.5+, so C2DM in Froyo is not an option.
I think wrap a persistent TCP connection in a service would be feasible. But I'm still wondering how to use one service to receive notifications for multiple applications. I don't want to create service and connection for each of my apps.
Should I try to register the same service in all my apps, or release the service as a single app?
Thanks in advance.
