I started with a small chat app for the friend circle only, the client part is quite simple, there's even no login, each dude will get an app version where he's already logged in. I'm just not sure how to use a service to monitor incoming messages since I'm not that familiar with that topic. The basic idea is the same for as for any messenger: a permanently running service (starts on boot) connects to the server at a certain interval and checks if there are any messages for the user (if network is not available, the service retries several times). In case there are some, a notification is shown. I'm aware of how to create such notifications, but I'm not sure how to implement and register the service. I DO NOT expect you to write code for me, I would just appreciate if someone points out the things I MUST do to get the thing working. Thanks in advance
EDIT as far as I understood, the best solution is to implement the Google Cloud Messaging support within the application and then create a servlet responsible for pushing notifications using GCM? Can somebody comment on this conclusion..
