Hello and welcome the development of Android. I hope you enjoy your stay: D. About your question:
What you ask is done with Service . If you want applications to register for events, which is usually done, this is the following:
- Create a service with all the logic.
- Make the service send Broadcast messages.
- All interested applications will receive a recipient class to receive this message.
I would like to know what you are trying to do to provide you further assistance.
