Hi, I have trouble getting my head around background activities and am wondering how to implement something like downloading the latest weather every 30 minutes?
Here is a sketch, please let me know if that makes sense? (1) Implement the download logic. (2) Let the Alarm Manager schedule the delivery of an Intent every 30 minutes (3) Build a BroadcastReceiver that listens to that Intent and as it is a BroadCastReveiver it can't bind to a Service ( I didn't really understand the documentation on that) it is not possible to access the interface of the Service. So startService() needs to be called instead with parameters that would need to be parsed in the startService method of the Service and dispatched to the actual method providing the service. That would at least work for calls without a return value. (4) Implement the actual method providing the service, call the download logic implemented in (1) and let it run in a separate thread. Does this make sense? And why would I need a service then? Why not instantiate the Runnable directly from the BroadCastReceiver? In the actual case I am looking into I have a BroadcastReceiver, some Activities and some Threads and the whole communication between those won't cross process boundaries. And where would I track the state of the Runnable, i.e. that it is currently running / downloading stuff? As a static member of some class? As a static member of the Service? And similar how to listen to a request to cancel the background operation, not necessarily the whole service, but this download? What seem to be best practices here?
