Exploring Long-Running Broadcast Service Abstraction

WakefulIntentService is a good abstraction. However, we want to go a step further so that our abstraction parallels the method of extending IntentService as in Listing 16-7 and does everything that an IntentService does but also provides few more benefits:

Pass the original intent that was passed to the broadcast receiver to the overridden method onHandleIntent. This allows us to largely hide the broadcast receiver, simulating a programming experience that a service is started in response to a broadcast message. This is really the goal for this abstraction while some extras are thrown in.

Acquire and release wake locks (similar to WakefulIntentService).

Deal with a service being restarted.

Allow a uniform way to deal with the wake lock for multiple receivers and multiple services in the same process.
