"If an activity is completely obscured by another activity, it is stopped. It still retains all state and member information, however, it is no longer visible to the user so its window is hidden and it will often be killed by the system when memory is needed elsewhere. If an activity is paused or stopped, the system can drop the activity from memory by either asking it to finish, or simply killing its process. When it is displayed again to the user, it must be completely restarted and restored to its previous state."

No. Activities shouldn't be depended on to process tasks in the background.

The following link illustrates the fundamentals of different Android components and what they do, i.e. the "parts" of an app.

You should be using a Service for background processing.

From what you're saying, I'd suggest an IntentService fired by an Alarm.
