Īs a developer, we just have to focus on our core business logic and implement it in the OnHandleIntent callback method. Stop point: Once the request Queue is empty it automatically stops itself, so the developer need not worry about handling the service lifecycle. Request Queue: It queues up all the incoming requests and they are processed one by oneģ. Thread management: It automatically processes all incoming requests in a separate thread taking the burden of thread management away from the developer.Ģ. Also intent service is a type of service that does a few specific things very well.ġ. Clients send requests through startService(Intent) calls the service is started as needed, handles each Intent in turn using a worker thread, and stops itself when it runs out of work. IntentService IntentService is a base class for Services that handle asynchronous requests (expressed as Intents) on demand. Service A Service is an application component representing either an application’s desire to perform a longer-running operation while not interacting with the user or to supply functionality for other applications to use. For other callback methods, the super is needed to be called so that it can be tracked properly.Ī Service is a broader implementation for the developer to set up background operations, while an IntentService is useful for “fire and forget” operations, taking care of background Thread creation and cleanup. And secondly, to implement onHandleIntent(). In brief, there are only two things to do to use IntentService. IntentService implements onStartCommand() that sends Intent to queue and to onHandleIntent(). This means that the IntentService can not be bound by default. IntentService implements onBind() that returns null. Meanwhile, IntentService automatically stops itself when there is no intent in queue. Service class needs a manual stop using stopSelf().
Thus, implementing a multi-thread should be made by extending Service class directly. IntentService creates a queue that passes one intent at a time to onHandleIntent(). Service class uses the application’s main thread, while IntentService creates a worker thread and uses that thread to run the service. Once done, the instance of IntentService terminate itself automatically. Examples for its usage would be to download a certain resources from the Internet.
The IntentService is used to perform a certain task in the background. Thus, IntentService, which is a direct subclass of Service is borned to make things easier. Service class is run in the application’s main thread which may reduce the application performance. Service is a base class of service implementation.
