Lecture 12: Android Services with example

Android Services with example:
A Service is an application component that can perform long-running operations in the background.
It does not provide a user interface.
Once started, a service might continue running for some time, even after the user switches to another application.
A service can handle network transactions, play music, perform file I/O, or interact with a content provider, all from the background.
Types of Services:
These are the three different types of services:
1. Foreground
2. Background
3. Bound
1. Foreground Services:
A foreground service performs some operation that is noticeable to the user.
For example, an audio app would use a foreground service to play an audio track.
2. Background Services:
A background service performs an operation that isn't directly noticed by the user.
For example, if an app used a service to compact its storage, that would usually be a background service.
3. Bound Services:
A service is bound when an application component binds to it by calling bindService().
Types of Services:
A bound service offers a client-server interface that allows components to interact with the service, send requests, receive results, and even do so across processes with interprocess communication (IPC).
A bound service runs only as long as another application component is bound to it.
Android Service Life Cycle:
In android, the life cycle of service will follow two different paths Started or Bound.
1. Started Service:
A service is Started when an application component, such as an activity calls startService() method.
Once it started, it will run indefinitely in background even if the component that started is destroyed.
